Now double-check whether there are any remaining files where Python used to be stored. Remove unwanted path name from %path% variable via batch.

The basic option would be to uninstall the unwanted Python version and re-install the favored one from. this website or an official Python guide) Option 2 Using VirtualEnv with multiple Python versions on windowsġ.) Open command prompt (“cmd”) and enter pip install virtualenv.Ģ.) Install your desired Python version via Remember: Do not add to PATH!ģ.) Type into the command prompt: virtualenv pathtoenv -p pathtopython_install.exe, whereas pathtoenv shall be the path where your virtual environment is going to be and pathtopython_install.exe the one where your freshly (presumably) installed Python version resides.Ĥ.) Done! You now have a virtual environment set up! Now, to activate the virtual environment execute the batch file which is located inside the pathtoenvScriptsactivate.bat.Easily manageable and the best part: There are lots of tutorials on the internet on how to approach this: With this approach, you easily can set up project-specific Python versions (as well as libraries). In general, it’s suggested to use virtual environments (I highly suggest looking at the official Python documentation). What follows are possibilities for Microsoft Windows, Linux, macOS and Misc.Īs mentioned those are just possibilities – by no means do I claim to have a complete list whatsoever. Here is a canonical summary which sums up different solutions for the variety of operating system Python runs on.
