Fixing PATH for Python libraries using Bash

问题

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.

I want to fix this issue to avoid problems in the future. I would greatly appreciate it if people could please take the time to explain how to do this.

回答1:

The error message is telling you to add /Users/you/Library/Python/3.7/bin to your path.

To do that, use a text editor to open /Users/you/.bashrc, and as the very last line add:

export PATH=/Users/you/Library/Python/3.7/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)
