Cannot import in pycharm 2017.2

[Chez]

I am using python2.7.14 and have a virtualenv setup and have installed psutil via Pycharm to the virtualenv. Importing in the console or from the terminal python is fine, nut it just will not import in Pycharm, so you have any ideas?

I am not a PyCharm user but I doubt anyone can have the slightest idea since you basically provided zero useful information.

If you can give me a list of commands and steps to reproduce your environment I would give this a shot.

Yes, sorry, it had been a long day. Anyway, If you setup two simple projects in Pycharm, both using the same 2.7.14 virtualenv with psutils installed: Thus,

Standard Vanilla Python Project:

main.py contains

import psutil

def x():
    print "hello world"

if __name__ == "__main__":
    x()

Google App Engine Project -
main.py contains

import webapp2
import psutil

class MainHandler(webapp2.RequestHandler):
    def get(self):
        self.response.write('Hello world!')

app = webapp2.WSGIApplication([
    ('/', MainHandler)
], debug=True)

The import in the vanilla python project works fine, but the import in the GAE app returns the traceback:

Traceback (most recent call last):
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/runtime/wsgi.py", line 240, in Handle
    handler = _config_handle.add_wsgi_middleware(self._LoadHandler())
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/runtime/wsgi.py", line 299, in _LoadHandler
    handler, path, err = LoadObject(self._handler)
  File "/Applications/GoogleAppEngineLauncher.app/Contents/Resources/GoogleAppEngine-default.bundle/Contents/Resources/google_appengine/google/appengine/runtime/wsgi.py", line 85, in LoadObject
    obj = __import__(path[0])
  File "/Users/chez 1/google-app-engine-projects/untitled/main.py", line 18, in <module>
    import psutil
ImportError: No module named psutil

Does Google webapp mess with imports? It looks like it's doing something with __import__ there.

[Chez]

I think it does, yes. It has a list of third party packages that you can specify in the app.yaml, unfortunately psutil is not on it. I have no idea why.

I came about this error via attempting to use Google cloud pubsub. The pubsub import works but that package calls types.py which imports psutil and fails everytime. There is an issue out there I found... googleapis/google-cloud-python#3892

I tried as per Google's recomendations for installing third party software "Using third-party libraries" online document. But this raises another exception:

"Using third-party libraries" online document.

File "/Users/chez 1/google-app-engine-projects/pitpit-gae/supplier/api/v1/handlers.py", line 9, in <module>

By the way, PyCharm is available for free for open-source projects: https://www.jetbrains.com/buy/opensource/

Closing this out as it seems related to PyCharm.
