Pycharm 4 no module named ROOT, when importing a locally installed module (PyROOT), that is working fine from shell on Mac OS X Yosemite

I am trying to set up PyROOT to work with Pycharm 4 on Mac OS X Yosemite.

I have installed ROOT (locally), with the python option enabled, and set up all of the necessary environment paths.

echo $PYTHONPATH
/Users/natalia/Software/root/lib:/Users/natalia/Software/root/bin:/Users/natalia/Software/root

It works just fine from the shell interpreter:

python
Python 2.7.6 (default, Sep  9 2014, 15:04:36)
[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.39)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import ROOT
>>> ROOT.__file__
'/Users/natalia/Software/root/lib/ROOT.pyc'
>>>

In Pycharm I have tried to add these paths to the interpreter using Preferences->Project Interpreter->More->Show paths...

The paths that show there are the following:

file:///Library/Python/2.7/site-packages/pip-6.1.1-py2.7.egg
file:///Users/natalia/Software/root/lib
file:///System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7
file:///System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-darwin
file:///System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac
file:///System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/plat-mac/lib-scriptpackages
file:///System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python
file:///System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk
file:///System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-dynload
file:///System/Library/Frameworks/Python.framework/Versions/2.7/Extras/lib/python/PyObjC
file:///Library/Python/2.7/site-packages
file:///Users/natalia/Software/root/bin
file:///Users/natalia/Software/root

I created the following file in Pycharm:

import os
os.system("echo $PYTHONPATH")
import ROOT

When run, it returns this:

Traceback (most recent call last):
/Users/natalia/Software:/Users/natalia/Software/root:/Users/natalia/Work/Projects/untitled
 File "/Users/natalia/Work/Projects/untitled/l.py", line 3, in <module>
    import ROOT
ImportError: No module named ROOT

Notice how this PYTHONPATH that's printed from python in Pycharm doesn't include (for a reason unknown to me) the path that actually includes the ROOT.pyc file, that is: '/Users/natalia/Software/root/lib'

I have also tried doing the dirty trick of

os.system("export PYTHONPATH=$PYTHONPATH:/Users/natalia/Software/root/lib")

but I found it doesn't actually change the path if I print it afterwards.

I am absolutely confused as to where Pycharm gets the paths from. Any possible solutions would be welcome and greatly appreciated.

Solution

You may have figured this out already, but just in case...

import sys
sys.path.append('/Applications/Misc/root/lib')
import ROOT
print ROOT.TTimeStamp().AsString()

will add that search path to Python (& PyCharm by extension); the snippet gives me the following output in PyCharm:

/Library/Frameworks/Python.framework/Versions/2.7/bin/python2.7
/Users/rrios/PycharmProjects/untitled/dummy.py
