Could not install packages due to an OSError: [WinError 2] No such file or directory

I try to use pip to install numpy, and I receive the following error message:

Python: Could not install packages due to an OSError: [Errno 2] No such file or directory 'c:\python39\Scripts\f2py.exe' -> 'c:\python39\Scripts\f2py.exe.deleteme'

I'm not sure about an older version of numpy installed first.

I ran just command prompt, not a one with admin privileges.

Can anyone help? Thanks.

I had the same issue.

First check if you see your package in pip installations and unistall it:

Run pip list
If you see the package in the list, then un install it: run pip uninstall [package_name].

Reinstall your package, but this time, add --user flag

pip install [package_name] --user

Unlike many answers, the solution in my case was not adding --user flag, but rather simply changing directories

I just so happened to try running the pip command from the site-packages folder of the package I was trying to upgrade. Obviously pip can't modify the directory you're currently in, so requiring the command to run from elsewhere makes perfect sense

just came across the same issue. For me, after running the file, (I am using visual studio), the current path I was in was given. So like C:\name\docs\file.py

The problem was that I had multiple python versions and only one of them had discord installed; you have to find out which version you're using. If you're unsure, type "py -v" wherever you are and look for something like python3.12 somewhere.

Then, you can finally do the above code for that version, e.g. py -3.12 -m pip install discord

depending on what you're doing you may also need to download the dotenv, which would be: ........ install python-dotenv as per here: https://pypi.org/project/python-dotenv/

OH, also, when installing dotenv you may have a WINOS-2 error, but dotenv will otherwise "have installed". Just type the same command and add --force at the end when you are installing it to the correct version of python. Hope this helps.

Adding --user to the command resolved the issue for me

pip install --upgrade openai

became

pip install --upgrade openai --user

and it worked.

For me creating a virtual environment and activating it resolved it.

Creating a virtual environment -

python3 -m venv virtualenvname

Activate the virtual environment On Linux, Unix or MacOS, using the terminal or bash shell:

source /path/to/venv/bin/activate

e.g. source virtualenvname/bin/activate

On Unix or MacOS, using the csh shell:

source /path/to/venv/bin/activate.csh

On Unix or MacOS, using the fish shell:

source /path/to/venv/bin/activate.fish

On Windows using the Command Prompt:

path\to\venv\Scripts\activate.bat

On Windows using PowerShell:

path\to\venv\Scripts\Activate.ps1

Deactivating the virtual environment On Linux, Unix or MacOS, using the terminal or bash shell:

deactivate

On Windows use the Command Prompt:

path\to\venv\Scripts\deactivate.bat

On Windows using PowerShell:

deactivate

This answer is for those who may use a different OS.

Source

Then install any package you need.

pip install numpy

I had a similar error using pip to install a different package on my Windows machine. The fix was to add the path to the python Scripts folder (C:\Python311\Scripts) to the PATH environmental variable.

Run the python command(s) in a command prompt with Administrator privileges

Note: To open the command prompt with Administrator privileges

Press the Win + R on your keyboard.
In the Run dialog box, type “cmd” into the field and then press Ctrl + Shift + Enter
Allow it to run in elevated privileges

I had the exact same problem while trying to install some packages. To resolve the problem, I added py -m before pip install.

For example:

py -m pip install requests

Or on a Mac computer

python3 -m pip install requests

I was getting this same error in VSCODE while I was creating a chatbot I tried running "pip install tensorflow" in the terminal almost 8-9 times and I figured out it was giving me a different error every time and after running the same script the error was solved.

One way to solve the error is to install the package scoped to the current user, without requiring elevated privileges. Try this out

pip install beautifulsoup4 certifi cffi charset-normalizer --user

You just simply add --user after line. This is the best answer!

In windows, right click on Python folder (mine is c:\Python311) and add your current user as owner with access rights onto the folder in the Security panel.

I know its a bit late, however there maybe users still having the same issue. This is mostly a priviledge issue. You need to install numpy with as Admin.

Open command prompt, and Run as Administator

Now install numpy

pip install numpy

and you should be good to go...

In my case deleting python folder from c:\users\(username)\appdata\roaming\ solved the issue because I've python already installed in c:\ drive root directory.

It's a privileges issue. In my case, there was a wheel.exe error popping up while force installing tensorflow_gpu. I escaped it by adding --user at the end of the command.

pip3 install --upgrade --force-reinstall tensorflow-gpu --user

Looking at the C/python/Scripts directory properties, the folder was marked as read-only. Changing that fixed the issue

The problem doesn't appear to be specific to numpy, and an elevated administrator prompt worked for me. I used gsudo to elevate a normal powershell prompt for the packages I was installing (which happened to include numpy).

Here's a sample session (with some parts elided with ... for brevity):

PS > pip install -r pkgs.txt
Collecting black
  Using cached black-22.3.0-cp310-cp310-win_amd64.whl (1.1 MB)
Collecting bs4
...

The fix:

PS > gsudo pip install -r pkgs.txt

I had the same problem with other packages. Just try

pip install 'package name' --user

and see if the issue is resolved. It worked out for me.

I had the same issue, in win 10, but it wasn't numpy that seems to have been the problem.

I was installing using pip install pyev3 saw this issue and came here.

I ran pip uninstall numpy then pip install pyev3 - no change, still failed.

I checked with pip list and numpy had been installed, so I then ran pip install hidapi, which worked and then ran pip install pyev3 which also then worked.

Hope this helps if you have a similar issue.

I also just encountered this. For me, it was because I forgot to activate my conda environment, which had numpy installed.

Check the answer recommending you try importing numpy and try that out. If numpy is unavailable, but you've installed numpy before, then most likely you have installed it either on another version of Python (one can have multiple versions installed - check your active version by typing python --version on the command line), or on a particular conda/pyenv/venv/other environment you forgot to activate.

For more info on Python package managers (which are out-of-scope for the question), see this guide: https://towardsdatascience.com/a-guide-to-conda-environments-bc6180fc533

Either way, you should be able to install/reinstall numpy, and get the f2py.exe file on your activated python installation and environment.

It seems like the package you are trying to install already exists, or you don't have privileges to install it.

First, try to import numpy and use it. If it doesn't work, try the second option.
Try to install numpy again with user privilege by running the command below:
```
pip install numpy --user
```

Try running the command as administrator:
or
