Anaconda Navigator won't launch (windows 10)

Anaconda navigator won't launch, I tried reinstalling it, that did not work either. anancondas' command prompt shows an error message. I've tried googling the answer, I guess I'm bad at it. [this is what I see after opening anaconda prompt]

p.s. I use spyder on it

Uninstall requests and urllib3 libraries using pip

pip uninstall requests
pip uninstall urllib3

Re-install them using pip

pip install requests
pip install urllib3

Run the below command after you change the working directory to the anaconda/scripts folder to check if it opens now

anaconda-navigator

This solution worked for me. Check if it works for you before uninstalling the entire application.

Could not launch Anaconda after reinstalling. I believe this was mentioned above but followed these four steps at the command line and worked perfectly:

conda update conda
conda update anaconda-navigator
anaconda-navigator --reset
anaconda-navigator

I faced a similar issue, None of the answers above worked for me. Your issue can have multiple reasons, maybe .condarc might have been corrupted, you can try to delete it and restart the Anaconda navigator. When your problem occurs, even conda install command might not work, in such case run the below command.

pip3 install pyOpenSSL --upgrade

After running the above command, Anaconda Navigator launched.

EDIT: i got the solution from here: https://github.com/conda/conda/issues/12234 This problem is different but it will still work for Anaconda navigator not launching. When Anaconda navigator didn't launch, i opened prompt to launch it from prompt, there i got an error, then i tried conda install then i got the error which is mentioned in the above link.

Install Anaconda again (without uninstalling the previous version) worked for me.

I am aware that this is an old question but I encountered this problem recently and I did not find the solution among the ones mentioned. After doing conda update --all jupyter-notebook and the others didn't launch anymore, then I had to do conda install anaconda-navigator = 1.10.0 because the problem could be with recent versions of anaconda.

Step 3 - tried launching anaconda navigator

I had to remove the member "Python" from username>AppData>Roaming(Python).

I renamed the member to username>AppData>Roaming(PythonBackup).

Python was partially still installed on my computer so it was having trouble installing it.

When I did get it installed it wasn't working and I found the Python on a traceback it gave when I tried to run Anaconda Navigator.

So none of the above answers worked for me.

I performed the following steps in order to make it work for me : OS : Windows 10 Home 64 Bit

Open Anaconda Prompt

conda remove anaconda-navigator
conda install anaconda-navigator

conda install -c anaconda pywin32 // Had to install since I got a module not found error // with just the above two commands

And it worked for me!!

I struggled with this problem for a couple of hours (got the same error message you showed in your attachment). I knew the problem had to do with the path variable, specifically the PYTHONHOME variable.

I finally found I had set the PYTHONHOME path to the python.exe file (C:\Anaconda3\python.exe). It should be set to the Anaconda folder that contains the python.exe file (C:\Anaconda3).

After that I could run the Anaconda Navigator.

I had the same problem which was mainly due to an update to PyQt5, the following code helped me.

Run cmd.exe as admin:

conda update conda
conda update anaconda-navigator

reinstall PyQt5:

pip uninstall PyQt5
pip install PyQt5
pip install pyqtwebengine

I tried the following @janny loco's answer first and then reset anaconda to get it to work.

Step 1:

activate root
conda update -n root conda
conda update --all

Step 2:

anaconda-navigator --reset

After running the update commands in step 1 and not seeing any success, I reset anaconda by running the command above based on what I found here.

I am not sure if it was the combination of updating conda and reseting the navigator or just one of the two. So, please try accordingly.

I was working on my Windows 10 machine and I'm not sure which package "broke" Spyder and Anaconda Navigator, but could have been either, or, or both Kivy-1.10.1 and moviepy-0.2.3.5 which gave me problems. I installed with either pip or conda. So of course I looked on this site to see what to do to fix. I found how pyqt was probably the issue. I uninstalled pyqt, kivy, and moviepy by using "pip uninstall ". I found where/or how they were installed by "pip list" and "conda list". After they were uninstalled I used "conda install - c anaconda pyqt" to reinstall pyqt. After installing pyqt I launched Spyder with no problems.

For me it worked doing this:

Uninstall the previous version: go to C:\users\username\anaconda3 and run the anaconda-uninstall.exe

Install again anaconda

then run the following commands on the anaconda pompt:

conda create -n my_env python=2.7

conda activate my_env

start the gui app

anaconda-navigator

You need to run the cmd prompt from the Scripts directory of Anaconda where ever you have the Anaconda parent folder installed. I happen to have in the root directory of the C drive on my Windows machine. If you are not familiar there are two ways to do that:

A) Use the key combination Win-key + R then type cmd and hit return to launch the terminal window and then type: cd C:\Anaconda\Scripts (or whatever directory path yours is).

B) Navigate using windows explorer to that Scripts directory then type cmd in the address bar of that window and hit return (that will launch the terminal already set to that directory).

Next type the follow commands waiting in between for each to complete:

activate root
conda update -n root conda
conda update --all

When complete type the following and Navigator hopefully should launch:

anaconda-navigator

I am not sure why but the command below worked for me.

pip install pyqt5

Of course I updated Anaconda and Navigator before running this command.

Faced the same problem. 'conda update' does not work; It gives the error : "CondaValueError: no package names supplied"

On executing the following commands, I was able to launch the Anaconda navigator:

conda update -n base conda

conda update anaconda-navigator

You need to update Anaconda using:

conda update

and

conda update anaconda-navigator

Try these commands on anaconda prompt and then try to launch navigator from the prompt itself using following command:

anaconda-navigator

If still the problem doesn't get solved, share the anaconda prompt logs here if they have any errors.
