CODE EXAMPLE FOR RUST

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.
