Access pip-installed CLI Tools

If you’re running pip install and installing a CLI tool, and you’re not able to find the tool, like shown below:

$ pip install diff-cover

$ which diff-cover
diff-cover not found

Then do this:

echo "export PATH=\"`python3 -m site --user-base`/bin:\$PATH\"" >> ~/.bashrc
source ~/.bashrc

This will add your path to the bin directory of your default Python interpretter (in this case python3), and you should be able to find your installed CLI tool.
