rust error: failed to run custom build command for python3-sys
/*
python3-sys uses a build script to determine the Python version and set
the correct linker arguments. By default it will attempt to use the
following in order:
- Any active Python virtualenv.
- The python executable (if it's a Python 3 interpreter).
- The python3 executable.
So the easiest way to deal with this is to create a python virtualenv in
your project folder.
