Unresolved Import in PyDev (Eclipse) even if path is in global PYTHONPATH

Question

I have the following code:

import sys

reload(sys)
sys.setdefaultencoding('utf8')#@UndefinedVariable

import phantomjs


if __name__ == '__main__':
    print ';'.join(sys.path)

I followed sth's answer in Permanently add a directory to PYTHONPATH

and added the phantomjs.pth file to ~/.local/lib/python2.7/site-packages which is where

python -c 'import site; site._script()' --user-site

told me I needed to add the pth files. In the phantomjs.pth file, I put the path where the phantomjs.py file is: /workspace/rankingmodel

It works for the python interpreter as

    print ';'.join(sys.path)

prints out (amongst others) /workspace/rankingmodel but eclipse marks

import phantomjs

with the error

Unresolved Import

How can I make that Eclispe and PyDev see the PYTHONPATH which I put in the .pth file?

One easy answer is to click on the Project menu, then Properties, then under the PyDev - PYTHONPATH section click the External libraries tab and add again the required paths there.

This is the workaround I am currently using.

But I was wondering if there was a better solution where eclipse can see the global paths itself, without having to be told explicitely.

The problem is with *.pth files which are not automatically updated in Eclipse PyDev. So the solution is to remove and then re-add the python interpreter in Eclipse.

I found the answer which I was looking for in the answer by Praveen Gollakota here: Importing using pydev and .pth files

For Linux, for Eclipse Kepler PyDev 3.9.1:

Drop down menu "Window", select "Preferences" On the left-side menu: PyDev->Interpreters->Python Interpreter Remove and re-add the python interpreter, and when you add it again make sure to click all the desired global python paths.
