virtualenvwrapper mkvirtualenv not working but no errors

Question

I'm working through Hitchhiker's Guide to Python's section on virtualenvwrapper, but am having difficulty creating a virtualenv. I don't receive any error when I try to create a virtualenv, but when I try to workon it, an error is thrown saying the env doesn't exist. My WORKON_HOME is empty. What might be the matter?

$ mkvirtualenv test
# NOTHING PRINTS HERE
$ workon test
ERROR: Environment 'test' does not exist. Create it with 'mkvirtualenv test'.
$ workon
# NOTHING PRINTS HERE

Relevant lines from my .bashrc, drawing on this question and the official installation guide:

export VIRTUALENVWRAPPER_PYTHON=/Library/Frameworks/Python.framework/Versions/3.7/bin/python3
export VIRTUALENVWRAPPER_VIRTUALENV=/Library/Frameworks/Python.framework/Versions/3.7/bin/virtualenvwrapper.sh
export WORKON_HOME=$HOME/.virtualenvs
export PROJECT_HOME=$HOME/Documents/Coding
source /Library/Frameworks/Python.framework/Versions/3.7/bin/virtualenvwrapper.sh

Looks like on the docs(virtualenvwrapper.readthedocs.io/en/latest/command_ref.html) the order of commands is different that yours. workon then mkvirtualenv test. — griffin_cosgrove

@griffin_cosgrove I believe they just run workon first to show that there are no virtual environments existing at that time, but then after creating a virtual environment with mkvirtualenv, workon will now show the new environment. I tried doing it in this order and it didn't change anything. — mrwnt10

I am not familiar with this library but there are other ways to make virtual environments. — griffin_cosgrove

Is virtualenvwrapper.sh sourced? type -a mkvirtualenv? Run exec bash -x and then mkvirtualenv test to see where it stops. — phd

I suspect the problem in this command: /Library/Frameworks/Python.framework/Versions/3.7/bin/virtualenvwrapper.sh test. It must be virtualenv, not /Library/Frameworks/Python.framework/Versions/3.7/bin/virtualenvwrapper.sh. You don't set VIRTUALENVWRAPPER_VIRTUALENV env var? — phd

Deleting the line

export VIRTUALENVWRAPPER_VIRTUALENV=/Library/Frameworks/Python.framework/Versions/3.7/bin/virtualenvwrapper.sh

from my .bashrc and re-sourcing the terminal solved the problem. I had mistakenly provided the path to virtualenvwrapper instead of virtualenv like the .bashrc did in the question I drew from.
