I am working with a Python virtual environment on a Windows machine. I used venv with Python 3.10 to create the environment and pip to install libraries. I have used this environment successfully with Jupyter Lab - launching it from the command line.
(as an aside, I then installed a separate Python 3.7 virtual environment that I used with PyCharm. The following error began after that action).
I now get the following error when I launch Jupyter Lab:
(extractpdf) C:\venv\extractpdf>jupyter lab
No pyvenv.cfg file
The above directory (C:\venv\extractpdf) does in fact contain a pyvenv.cfg file with the following content, which looks as expected according to this answer:
home = C:\Python310
include-system-site-packages = false
version = 3.10.1
I deleted the virtual environment, reinstalled Python 3.10.1, and recreated the virtual environment, while this error persists.
This error is occurring with my virtual environments, even when a pyvenv.cfg file exists. The following system interpreters do not have a pyvenv.cfg file.
My Python 3.7 system interpreter gives this error:
C:\Python37>python
No pyvenv.cfg file
while my Python 3.10 system interpreter does not produce an error.
C:\Python310>python
