  If you get this error when attempting to run a debug session or build within Visual Studio 2019 using ASP.NET Core 3.1, then run the following command:

  Run powershell as Administrator:
  and run
  npm --add-python-to-path='true' --debug install --global windows-build-tools

  You should see the windows-build-tools installed successfully and the Python issue resolved in the output:
