Fixing PATH for Python libraries using Bash
Question:
I am attempting to install some Python libraries by executing variations of the following command in Bash:
pip install --user -U numpy
I installed Python3 using Homebrew.
I then get variations of the following message each time:
WARNING: The scripts f2py, f2py3 and f2py3.7 are installed in ‘/Users/x/Library/Python/3.7/bin’ which is not on PATH.
Consider adding this directory to PATH or, if you prefer to suppress this warning, use –no-warn-script-location.
How can I fix this issue to avoid problems in the future?
Answers:
The error message is telling you to add Python 3 to your path.
To do that, use a text editor to open /Users/<you>/.profile
, and as the very last line add:
export PATH=/Users/<you>/Library/Python/3.8/bin:$PATH
Then you’ll need to launch a new Terminal window for those settings to take effect. (you could make it take effect in your current shell by entering the line directly into your shell)
[Edit: now that macOS 12.3 has removed all versions of Python, Homebrew is the easiest way to install Python. Fortunately things are simpler because there’s only one version of Python on your system and you won’t need to override the system’s version (because there isn’t one any longer).]
Update: As of python 3.8, the following path should be used:
export PATH=/Library/Frameworks/Python.framework/Versions/3.8/bin:$PATH
If you’re using bash, you can store this in your /.bashrc
If you’re using zsh, you can store this in your /.zshrc
You have to update the seeking path location, to needed bin
folder, in your .zshrc
, .bashrc
etc.
Example
For /Library/Python/3.8/bin
,
you can prepend the variable $HOME
, and use with the needed path:
export PATH="$HOME/Library/Python/3.8/bin:$PATH"
Epilogue
In current Terminal
tab, you have to reload your shell, with the config, by . ~/.zshrc
, or .bashrc
etc
export PATH=/Users/x/Library/Python/3.8/bin:$PATH
above is the command to save the problem, you are going to paste this on your terminal window and in the place of x
you are going to write your name on Mac. eg=RavikantSingh — it is my name you can write yours
