Problem for pipenv with conda

[AlekseiKhatkevich]

In your documentation it said that it is possible to use Pipenv with conda:

https://pipenv.pypa.io/en/latest/advanced/#pipenv-and-other-python-distributions

But it does not work even on a freshly created project:

Expected result - Pipenv would install packages inside Conda envirment and would use conda python interpreter.

Actual result - error during Pipenv initializations

python console

import sys
sys.executable
'C:\\ProgramData\\Miniconda3\\envs\\new_project\\python.exe'

terminal

pipenv install --python=C:\\ProgramData\\Miniconda3\\envs\\new_project\\python.exe

# result

Failed to create virtual environment.

pipenv, version 2020.11.15
conda 4.8.5
Windows 10
python 3.7.9

Would be glad to have this possible bug fixed or point me out what i did wrong if so.

I use Pipenv over 2 years already. Great tool.

Thank you

Have you tried directing pipenv to use a python.exe that isn't part of an existing virtual environment?

[AlekseiKhatkevich]

Yes. This way it works correctly. Also i have tried install Pipenv inside Conda via 'conda install pipenv' and run it from there. Same error.

FYI - conda and virtualenv 20.0.34+ don't play well together, see ContinuumIO/anaconda-issues#12094 and pypa/virtualenv#1986. The current suggested workaround is to downgrade to virtualenv 20.0.33.
