I have tried to run a remote debugging session. When I inserted the directive: "from pydev import pydevd" editor warned me about the unresolved reference to pydev, so I tried embedded python console. The same directive raised there the exception "ImportError: No module named pydev".
I checked my pythonpath from the console - there is one reference to pydev in sys.path:
'C:\\Program Files\\JetBrains\\PyCharm 2.6\\helpers\\pydev'
which renders to the proper path. I wonder if the whitespaces causes the problem? (PyCharm runs on Windows XP with Python 2.7 here.)
