How to setup environemnt to load python library?

Question

I am trying to import pyroscope module which is residing in my ~/lib/pyroscope directory. The example here shows that the script use from pyrocore.scripts import base . I don't see any tricks based on imp.load_source . So I am kinda puzzled - what kind of environment I have to build in order to import this module( without relocating the library )?

You have to make sure that ~/lib is in the path python uses to look for libraries. One way to do this is set the PYTHONPATH environment variable in a shell:

export PYTHONPATH=~/lib

Alternatively, you can change the path in your script before the import :

import os
import sys
sys.path.insert(0, os.path.expanduser('~/lib'))

For more information, please have a look at The Module Search Path in the documentation.
