Pipenv: Bug with fresh install/upgrade

[PierreLeGuen]

Hello ! Just upgraded pipenv from the AUR and then from pip, and I always get the same issue :
(PS : the previous version worked)

$ pipenv install numpy
Traceback (most recent call last):
  File "/home/pierrelg/.local/lib/python3.7/site-packages/pipenv/project.py", line 509, in _parse_pipfile

During handling of the above exception, another exception occurred:

What is your Pipfile

[PierreLeGuen]

Hello @uranusjr , thanks for the answer.
My current Pipfile is this (he is here just for testing) :

[requires]
python_version = '3.7.0'

[uranusjr]

Hmm, I cannot seem to produce this. The error message indicates the TOML file (Pipfile) is invalid, but everything seems to be fine. Can you try deleting the Pipfile and run the command again, to make sure there are no invisible characters in the file?

[PierreLeGuen]

I tried to delete it completely and then to start without Pipfile = same issue.
I reinstalled pipenv after a complete purge and it still happens.
Any other insights please ?

[uranusjr]

Unfortunately no, it is really strange, I am stumped :(

[PierreLeGuen]

Still trying to figure it out.
When I create a pipenv in a random folder it works:

To activate this project's virtualenv, run pipenv shell.
Alternatively, run a command inside the virtualenv with pipenv run.

But when I try again in my project without Pipfile, I get this:

[PierreLeGuen]

RESOLVED (after reinstalling from the AUR):
I removed everything from the virtualenvs folder [pierrelg@pierre-HP ~]$ cd /home/pierrelg/.local/share/virtualenvs/ and then rm -r ./the_folder
And now it works !

[Diego-Beckdorf]

Got same error and seams to be that the single quote is not accepted.
