There are two options I’m aware of.
One, change the PYTHONPATH
environment variable to include the directory above your module.
Alternatively, edit ~/.pylintrc
to include the directory above your module, like this:
[MASTER]
init-hook='import sys; sys.path.append("/path/to/root")'
(Or in other version of pylint, the init-hook requires you to change [General] to [MASTER])
Both of these options ought to work.
Hope that helps.
