How to change the base python version when multiple versions are installed?

abhishekchitwar

Description: I have several Python interpreters installed in my system (3.8, 3.10 and 3.11). The default version is 3.11 which is incompatible with the solution application framework (need 3.7 or 3.8). I want to switch to 3.8. 

Solution: Edit the PATH environment variable, by moving the desired version of python to the top in Environment Variables Setting. Update it at System as well as Users Variables sections.

e.g.,

by setting this, it launches the version which user has set as above, in this case Python 3.8. However, issuing a command "py -0p" is not showing the active version as 3.8, check below snapshot which is confusing.

Have you face such issue with multiple python versions? Any suggestions are welcome. Thanks!

Hello!

I would suggest using the full path to your 3.8 interpreter to create the virtual environment. To create a virtual environment with the desired python interpreter, you can use

C:/full/path/to/python.exe -m venv .venv

In our case, you would replace the creation of the venv with simply running setup_environment.py in a similar way, since setup_environment.py will create the venv for you with the same python interpreter:

C:/full/path/to/python.exe setup_environment.py

Would this work for you?
