the pipenv install command have worked very well before, but today it gives this error message. Does anyone know this issue?
I also tried to install other packages to test if it's a problem of the package or the source, for example, pipenv install numpy, but still, it gives me the same error messages.

Answer 1

Sorry I'm back, I solved my problem just now, I should have if I searched longer. This works for my problem:
cd project_name
pipenv install setuptools_scm
pipenv install django-haystack
although I don't know the reason, but a setuptools_scm package is needed.
