title: "No Python at..." error after installing different version and changing the path variable
body: <p>I use Windows 10. I was trying to pip install Vectorbt but the installation could not have been finished because there was an error when numba and llvmlite were suppose to be installed. I was using Python 3.10 and read that there is a compatibility problem with it. So I uninstalled it and installed Python 3.8.7. Afterwards I made sure that the system variable is set on the proper Python path. I closed everything and even restarted the system but in the command line or the powershell terminal in VSC I get the error &quot;No Python at&quot; and the directory of the previous 3.10 installation.
  The variable is set corectly (was set as an admin).</p>
  <p>Any ideas?</p>
  <p>Maybe something with the registry?</p>
  <p>Thanks!</p>
