pipenv and eric?

[Christian Haul]

Hi all,
I'm still quite new to python and am just starting to get my head around
virtual environments. I got the impression that pipenv
https://pipenv.pypa.io/en/latest/ is the way to go.

How could I use such an environment it eric?

IIUC pipenv creates regular virtualenv environments.

$ pipenv --python 3.8

On the console, everything is fine, i.e. I can run a program that uses
the ldap3 library.

But, how to configure this in eric?

In Extras->Virtualenv Manager add a new environment
name (does it matter?): pipenv
directory: /home/xyz/projects/python/piptest
python: /usr/bin/python3.8
python variant: python-3
(no checkboxes checked)
prefix:

In window "PyPI" select "piptest", local packages: (empty)

(was expecting ldap3 !?)

In Run->Run Script
Virtual Environment: pipenv
Parameters:
Working Directory: /home/xyz/projects/python/piptest
Environment Variables:

=> unhandled ModuleNotFoundError
„No module named 'ldap3'“

Can someone point me to some documentation / tutorial on how to use
pipenv with eric? Or spot the error above?

TIA
Chris.
