Help request: Using packages from both Pipenv & Conda #4897

Closed boonware closed 2 years ago

boonware commented 2 years ago

I am attempting to use packages installed by both Pipenv and Conda. Since Conda does not support "dev dependencies" I am using Pipenv to install packages such as Pytest. To run the tests I invoke the following:

pipenv install --dev
pipenv --python=$(conda run which python) --site-packages run pytest test

My Pipfile is:

[[source]]
url = "https://pypi.org/simple"
verify_ssl = true
name = "pypi"

[dev-packages]
pytest = '6.2.3'

I receive the following error:

Error: the command pytest could not be found within PATH or Pipfile's [scripts].

Am I doing something wrong? With the command above I assumed that both packages installed by Pipenv and those in the Conda environment would be available.

Pipenv version: 2021.11.23

@boonware I think I figured this one out. You should only pass --site-packages and --python the first time you run the pipenv to setup your virtualenv. Try this:

pipenv --rm
pipenv --python=$(conda run which python) --site-packages
pipenv run pytest test

As an example, since I don't have conda, I did this using my system python and first installed celery at the system level. Then see:
