how to manage sys.path globally in pycharm

Question

I have a bunch of unittests that import stuff not from /python2.7/site-packages/ but from a completely different directory. So what I do is do some monkey-patching in each test file with sys.path.append to make my Python see what I need.

Is there a way to append sys.path globally for the whole Pycharm project without bothering with each and every file?

UPDATE: setting default working directory doesn't help. For example, if I set the working directory to /Users/1111/_projects/_empty_dir/ like so:

and then run this

import sys
for p in sys.path: print p

what I see is this

/Users/1111/.virtualenvs/blesk/bin/python /Users/1111/_projects/_testing_pycharm/importer.py

and there is no /Users/1111/_projects/_empty_dir/ on sys.path.

Answer 1

This is one fairly easy, follow this path:

1. settings
2. project: <your project name>
3. project interpreter
4. select the interpreter you want to update sys.path for
5. find the bottom right icon, 'show paths for the selected interpreter'
6. add the folder to the list of paths.

Answer 2

There is now a better way to do it. You can Mark Directory as as Sources root. This option will appear in the bottom when you right click on any directory in Project.
