virtualenvwrapper_run_hook:12: no such file or directory: /usr/local/bin/python3
virtualenvwrapper.sh: There was a problem running the initialization hooks.

If Python could not import the module virtualenvwrapper.hook_loader,
check that virtualenvwrapper has been installed for
VIRTUALENVWRAPPER_PYTHON=/usr/local/bin/python3 and that PATH is
set properly.

Which python command

/usr/bin/python

Python version command

Python 2.7.16

Which python3 command

/Library/Frameworks/Python.framework/Versions/3.7/bin/python3

Python version3 command

Python 3.7.4

pip3 --version command

pip 19.3.1 from /Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/pip (python 3.7)

Virtualenvwrapper needs to know correct python3 path.

Try to set variable containing path to python3 running following command:

export VIRTUALENVWRAPPER_PYTHON=/Library/Frameworks/Python.framework/Versions/3.7/bin/python3

If it helps, you should run this command every time you initialize a bash or zsh session.

To do this automatically, add the command to your ~/.bashrc or ~/.zshrc file, depending on what you use.
