Getting pipenv internal error while trying to run this command “ pipenv lock ” with pycharm in mac OS

Question

I am new to python and pipenv. when I run pipenv lock ,I got the following error, I have reinstall pipenv and search the error on google but I still can not fix the error. Last time when I opened the projects with pipenv it is ok, why now it is bad? Is there any relationship with oh-my-zsh?

Answer 1

Check your Pipfile if there is a typo? I got the same error when the Pipfile has a typo, yours I think it is in line 45
