pipenv: pipenv cannot install pyautogui module, but pip can

I tried to install pyautogui in Python 3.6 using “pipenv install” and received the below error message. I proceeded to enter the bash shell, and used pip3 to install the module to my virtualenv without issue. I’m not sure why pip would work and pipenv wouldn’t.

“pipenv run pip3 install pyautogui” installs the module as well.
