Pipenv Install RuntimeError: location not created nor specified

Question

I am using Pipenv to manage project dependencies. It was working fine so far until now. Now I am trying to bootstrap an environment with pipenv install and I am getting the following error:

❯ pipenv install --dev --skip-lock

I have installed Pipenv with Homebrew. I am not sure what could have changed to stop working. Other older projects keep working, but every time that I try to create an environment I get this error.

Thanks!

Answer 1

So I manage to make it work. My default python system installation was 3.7.3. However, pipenv didn't like that one for some reason. I installed python 3.7.7 with homebrew and pipenv was able to locate that version properly and use it to create a virtual environment.

In summary, to fix this issue try to install python again. In my case:

brew install python
