title: ImportError: No module named psutil while using robotframework
body: <p>I'm using robotframework for automation. I'm trying to use a method from my python library which needs psutil. The problem is when I execute from the robotframwork it gives error <code>ImportError: No module named psutil</code>  but when I execute it with Pycharm I don't get any error. I have installed psutil using <code>pip install psutil</code> . I searched a lot on web but couldn't find any reason for this issue. </p>
