问题
I am on OS X El Capitan.
I want to import psutil for a python script, but get module psutil not found.
If I do pip install psutil I get psutil already installed.
How is this possible that I have psutil installed, but it does not find it in the script?
I am using both macports and homebrew to install several python packages. Maybe this is a problem?
Any ideas how I can get psutil to import?
I have python27 and python34 on my system. For this project I need to use python27.
This is my log for pip freeze

I was unable to reproduce your problem in a virtualenv, below are the steps I used.
Desktop $ virtualenv -p python2.7 virtenv
Desktop $ cd virtenv
virtenv $ source bin/activate
(virtenv) $ sudo pip install psutil
(virtenv) $ python
(virtenv) > import psutil
(virtenv) > exit()
(virtenv) $ deactivate
You could try removing it and reinstalling it.

Just tried to run glances, some kind of diagnostic tool that requires psutil aswell. Unfortunatelly got an error :
PsUtil module not found. Glances cannot start.
Ran pip freeze, saw that i had it installed and i decided to remove and try to reinstall. Uninstalled (Successfully uninstalled psutil-5.0.1) and when tried again to install psutil-5.0.1 failed. Ran again pip freeze and noticed there is a minor version (psutil==2.2.1) that is served in case you remove the latest (very strange). Anyway, run again pip uninstall psutil, removed that minor version and when i tried again to reinstall worked correctly, installing the last version.
Now everything works ok.
