So, i had 2 python versions installed on my new system, one in. So, after some hairs lost - I also installed the old python version 3.7.4 in the specific path stated in the pyenv.cfg file (C:\Program Files (x86)\Python37-32).

Then - my system crashed - reinstalled windows 10, and downloaded again python, but this time python 3.8, and it installed in C:\Program Files (x86)\Python38-32 Home = C:\Program Files (x86)\Python37-32 The install-directory of python was c:\Program Files (x86)\python 37-32Įach project had a file /venv/pyvenv.cfg, and in this file there was the line my undertanding is/was that all the files in these virtual environment where 'stand alone', so sufficient to run a python 3.7.4 for that specific projec files, and not depending on files of the home-python-dir. I made al my (practice)projects with that, and each project had a venv/scripts/python3.7.exe in it. In the old system setup I used python 3.7.4. Well, i'm pritty new to Python, and I did too had a re-install of my os after a crash So, if the path in that file becomes invalid, the virtualenv's Python interpreter will be unable to find any standard modules except those few that were copied. It is used to add the base installation's Lib to sys.path via a custom site.py.

Since virtualenv is not a full installation, it must have a path to its base installation stored somewhere to be able to use files from there.Īs of this writing, virtualenv ( v16.0.0) in Windows is implemented like this: Path in the virtualenv to its base installation this is what my list looks like after I deleted an Anaconda installation: Or edit them and specify correct paths.Į.g. Then delete and recreate the necessary entries. Go to the interpreter settings for your project in File->Settings.->Project interpreter->(Gear icon)->Show all.: So, if that path changed, P圜harm's saved path has become invalid. P圜harm needs to know the path to your environment to run things in it. There are (at least) two primary suspects: Path to your virtualenv in P圜harm settings Most probably, some path to Python environment that P圜harm tries to use has become invalid somewhere. I only tried to set PYTHONPATH=C:\Anaconda3\envs\python37 on Windows and then to activate venv. I believe that there is an environment variable to overide the venv config value.

Unfortunatelly, I need to update pyvenv.cfg depending on the PC in use. The base python paths depend on the very PC. My case: I have a project in a network share and try accessing it from different computers. You still need your base python that had been used for venv creation. It does not provide an isolated python installation. Virtual environment implies that all libraries and settings are isolated from other projects. Thus your virtual environment fails to locate the python installation. What solution is: Check out venv\pyvenv.cfg and provide a valid path to the basic python installation.Īfter reinstalling your OS, you have no base python interpreter reinstalled or you have installed it at different location than before.
