How can I run Conda?

I installed Anaconda and can run Python, so I assume that I installed it correctly. Following this introductory documentation, I am trying to install Python v3.3, so I am copying and pasting the following line into my console:

conda create -n py33 python=3.3 anaconda

However, that gives me an error:

-bash: conda: command not found

What do I need to do to run Conda?

I am working on a Linux system.

Using the export PATH= strategy with conda activate will result into a warning message for Conda 4.4 or later.

The recommended way (see this release note, and this post) to do it is to remove the export PATH=... line and instead add the following line in your .bashrc (or .bash_profile) file:

. ~/anaconda2/etc/profile.d/conda.sh

Furthermore, if you want Conda to be activated by default, add:

conda activate

The main point is that, as of December 2018, it's Scripts, not bin.


Updating $PATH in Git Bash for Windows

Use one of these: export PATH=$USERPROFILE/AppData/Local/Continuum/anaconda2/Scripts/:$PATH export PATH=$USERPROFILE/AppData/Local/Continuum/anaconda3/Scripts/:$PATH


Updating $PATH in the Windows default command line

Use one of these: SET PATH=%USERPROFILE%\AppData\Local\Continuum\anaconda2\Scripts\;%PATH% SET PATH=%USERPROFILE%\AppData\Local\Continuum\anaconda3\Scripts\;%PATH%


Updating $PATH in Linux

Change /app to your installation location. If you installed Anaconda change Miniconda to Anaconda. Also, check for Script vs. bin,

export PATH="/app/Miniconda/bin:$PATH"

You may need to run set -a before setting the path, I think this is important if you're setting the path in a script. For example if you have your export command in a file called set_my_path.sh, I think you'd need to do set -a; source("set_my_path.sh").

The set -a will make your changes to the path persist for your session, but they are still not permanent.

For a more permanent solution add the command to ~/.bashrc. The installers may offer to add something like this to your ~/.bashrc file, but you can do it too (or comment it out to undo it).


General Observations:

Background: I installed the 64-bit versions of Anaconda 2 and 3 recently on my Windows 10 machine following the recommended installation steps in December of 2018.

  • Adding Conda also enables IPython, which works much better in the native Windows command line
  • Following the strongly recommended installation does not add Conda or IPython to the path
  • Anaconda 3 doesn't seem to install a command prompt application, but Anaconda 2 did have a command prompt application
  • The /bin folder seems to have been replaced with Scripts
  • Poking around in the Scripts folder is interesting, maybe the Anaconda command prompt application is in there somewhere.

Open your terminal and type the following command to add Anaconda to environment path.

For Anaconda 2:

export PATH=~/anaconda2/bin:$PATH

For Anaconda 3:

export PATH=~/anaconda3/bin:$PATH

Then, to check the Conda version, just type,

conda --version

Create an environment using the following command,

conda create --name myenv

Activate the source using,

source activate myenv

Then your Anaconda IDE is ready!

Similar to the above, remember that you could have Miniconda instead of Conda, so you might want to add

export PATH=${PATH}:/Users/davidfortini/miniconda3/bin to .zshrc or .bash_profile and then reboot the terminal.

Use conda init

As pointed out in a different answer, manually adding Conda on $PATH is no longer recommended as of v4.4.0 (see Release Notes). Furthermore, since Conda v4.6 new functionality to manage shell initialization via the conda init command was introduced. Hence, the updated recommendation is to run

Linux/UNIX and OS X before macOS v10.15 (Catalina)

./anaconda3/bin/conda init

Mac OS X v10.15 (Catalina) and later

./anaconda3/bin/conda init zsh

Windows

./anaconda3/Scripts/conda.exe init

You must launch a new shell or source your init file (e.g., source .bashrc) for the changes to take effect.

Details. For an in-depth look at exactly what conda init does see this answer.

Alternative shells

You may need to explicitly identify your shell to Conda. For example, if you run zsh (Mac OS X 10.15+ default) instead of bash then you would run

./anaconda3/bin/conda init zsh

Please see ./anaconda3/bin/conda init --help for a comprehensive list of supported shells.

Word of Caution

I'd recommend running the above command with a --dry-run|-d flag and a verbosity (-v) flag, in order to see exactly what it would do. If you don't already have a Conda-managed section in your shell run commands file (e.g., .bashrc), then this should appear like a straight-forward insertion of some new lines. If it isn't such a straightforward insertion, I'd recommend clearing any previous Conda sections from $PATH and the relevant shell initialization files (e.g., bashrc) first.

Again, for those interested, there is an in-depth look at how it works, in this answer.

Potential Automated Cleanup

Conda v4.6.9 introduced a --reverse flag that automates removing the changes that are inserted by conda init.

If you have just installed Anaconda and got this error, then I think you forgot to run this command:

  • source ~/.bashrc

This will enable you to make use of Anaconda in terminal.

This may seems simple, but many (including me) do this mistake.

If the error is still persisting, you have to verify if anaconda location is added to PATH in your system.

Once you add it, you'll be fine.

To edit .bashrc in Ubuntu:

/usr/bin/vim ~/.bashrc

Type PATH=$PATH:$HOME/anaconda3/bin.

Press Esc and :wq to save the .bashrc file and exit Vim.

Enter image description here

Then

export PATH=~/anaconda3/bin:$PATH

And type source ~/.bashrc.

Now to confirm the installation of Conda, type

conda --version

Answer for

  1. Unfortunately, the installer puts the PATH definition only into .bash_profile, but not the .zshrc configuration.
  2. Contrary to the given answers, it doesn't (necessarily) install in ~/anaconda3/, but instead in /anaconda3/.

The PATH defintion in file .zshrc must therefore be this:

...
# Anaconda3
export PATH="/anaconda3/bin:$PATH"
...

I also was facing the same issue. This might be the simplest possible solution:

source anaconda/bin/activate

For Anaconda 2, use

source anaconda2/bin/activate

Depending on the name of the directory, then execute your command, i.e., conda --create.

I'm on macOS v10.13 (High Sierra) and just installed Anaconda 3 via a Homebrew command. I had an issue with running:

conda

It'd also give me:

-bash: conda: command not found

I tried running:

export PATH=~/anaconda3/bin:$PATH

But it needs entire path. So here are the correct steps:

nano ~/.bash_profile

Now export the entire path. In my case it was:

export PATH=/usr/local/anaconda3/bin:$PATH

Exit out and run:

source ~/.bash_profile

Then try:

conda

For example,

conda --version

Output:

conda 4.4.10

Mostly, it is because when we install Anaconda in the end, it adds the Anaconda path to PATH variable in the .bashrc file.

So we just need to restart the terminal or just do:

source ~/.bashrc

If still it doesn't work, then follow these commands:

cat >> ~/.bashrc

Paste the below command for Anaconda 3:

export PATH=~/anaconda3/bin:$PATH

Hit Enter and then Ctrl + D.

source ~/.bashrc

  1. Check where you have installed Anaconda. In my case it looks like /home/nour/anaconda3/bin

  2. Open your .bashrc file. For example, gedit .bashrc

  3. Add this export PATH = /home/nour/anaconda3/bin:$PATH line at the end of the file and save.

  4. Reopen the terminal. Type conda --version

Note: Make sure the path in 1. and 3. are the same. In my case, /home/nour/anaconda3/bin.

My environment: macOS and Anaconda 3

This works for me:

nano ~/.bash_profile

Add this:

export PATH=~/anaconda3/bin:$PATH

The export path must match with the actual path of executable anaconda3 in the system.

Exit out and run:

source ~/.bash_profile

Then try:

jupyter notebook

First, check the location of Anaconda. For me, I installed Anaconda 3 at the / directory which I access with /anaconda3.

Then in your terminal, input export PATH="<base location>/anaconda3/bin:$PATH". For me, it's export PATH="/anaconda3/bin:$PATH".

Finally, input source $/anaconda3/bin/activate. For you, just change to your location.

Now, you could try conda list to test.

Also, visit the installation guide.

I had the same issue. I removed the Anaconda directory from the install location and reinstalled. After that, it worked as I anticipated.

If you have just installed Miniconda or Anaconda make sure you rerun your terminal.

From this, I mean close and open your terminal and then try conda list to verify your installation.

For me, this worked!!

You need to put Anaconda.sh to your /home/<your_name_file>, and then run it to install. After that, you can runexport PATH=~/anaconda3/bin:$PATH. Remark: do not run Anaconda.sh in download/ directly!

I am setting up a virtual machine running Ubuntu. I have Anaconda 3 installed in the "Home" folder. When I typed "conda" into the terminal I was getting the error "conda: command not found" too.

Typing the code below into the terminal worked for me...

export PATH=$PATH:$HOME/anaconda3/bin

to check it worked I typed:

conda --version

which responded with the version number.

System: macOS

I installed Anaconda first, and everything worked well. Then I installed iTerm2 and when I typed Python, iTerm2 gave me the default Python. Here is how to find your Anaconda Python back:

  1. Open your .zshrc file. For example, vim ~/.zshrc

  2. Then add export PATH="/Users/yourusername/anaconda2/bin:$PATH" to the last line of the file. Note that you need to replace the yourusername to your user name and make sure you have anaconda2. An easy way is to copy this line from ~/.bash_profile.

  3. Save the file, close it, relaunch the terminal and now Anaconda Python should be back.

For Windows:

A recent Anaconda (version 4.4.0) changed some directories. You can find "conda" in Anaconda3/Scripts, instead of Anaconda3/bin.

Run

cat ~/.bash_profile

to check if Anaconda is there. If not, you should add its path there. If Conda is there, copy the entire row that you see the Anaconda there from "export" to the end of line.

Like this:

export PATH=~/anaconda3/bin:$PATH

Run this in your terminal.

Then run

conda --version

to see if it is exported and running!

In my case, the Conda path was properly set (in .bashrc) by the Conda installation Bash script. But to make it works I had to give executable file permissions to files in bin sub folder with chmod +x *.

My system information:

  • Conda 4.2.9

  • Operating System: Debian 8 GNU/Linux 8 (Jessie)

  • Kernel: Linux 3.16.0-4-amd64

  • Architecture: x86-64

This information is current as of 2016-08-10. Here are the exact steps I took to fix this using methods posted above. I did not see anyone post: export PATH=$PATH:$HOME/anaconda/bin (you need to add export to the beginning of the line).

Here it is, step-by-step:

For anyone running into the same problem while using Oh My Zsh, you need to do the following:

  • Open your .zshrc in your terminal. I am using iTerm 2 and have Sublime Text 3 as my default text editor:

    subl ~/.zshrc

  • Once the file opens in your text editor, scroll to the very bottom and add:

    export PATH=$PATH:$HOME/anaconda/bin

  • Save the file, then close it.

  • Close your terminal, then relaunch it.

  • Once back in your terminal, type:

    conda --v

    You should then see the version of conda installed printed on your screen.

If you're using Z shell (executable zsh), then after doing that, your terminal may show you zsh: command not found: rvm-prompt.

The solution is:

  1. add alias rvm-prompt=$HOME/.rvm/bin/rvm-prompt within .zshrc file.
  2. type source .zshrc.

Then the zsh: command not found: rvm-prompt will disappear.

If you have installed Anaconda and have definitely said yes to the:

Do you wish the installer to prepend the Anaconda install location to PATH in your /home/name/.bashrc ? [yes¦no]

question then you maybe just need to restart your terminal window. The change won't take effect until you either (1) close and reopen the current window or (2) just open and start working in a new window

Basically, open a new console window and see if it works now.

You might want to try this:

For Anaconda 2:

export PATH=~/anaconda2/bin:$PATH

For Anaconda 3:

export PATH=~/anaconda3/bin:$PATH

For Anaconda 4:

Use the Anaconda Prompt.

And then

conda --version

to confirm that it worked.

The export PATH=~/anaconda3/bin:$PATH works, but it stops when you exit the terminal in order change that you have to run sudo nano ~/.bashrc and then copy the path into the file and save it after that you activate the changes using source .bashrc.

Check with conda install anaconda-navigator. If not installed, follow the Anaconda install instructions again

If you have installed Anaconda, but if you are not able to execute a Conda command from the terminal, it means the path is probably not set, try:

export PATH=~/anaconda/bin:$PATH

If you have installed Anaconda, but you are not able to load the correct versions of Python and IPython, or if you see "conda: command not found" when trying to use Conda, this may be an issue with your PATH environment variable. At the prompt, type:

export PATH=~/anaconda/bin:$PATH

For this example, it is assumed that Anaconda is installed in the default ~/anaconda location.
