How do I get IntelliJ to recognize common Python modules

Question

I m using IntelliJ 10 IDEA Ultimate Edition    I ve created a new file Test py  and IntelliJ has correctly switched to Python parsing mode   I can confirm this by typing  d   it pops up  def  as a suggestion  and hitting tab correctly gives me  def      However  when I try this code     import os  cwd   os getcw  lt Ctrl-space gt    Two things happen       I get a squggly underline underneath os and hovering over it gives me a  Unresolved reference  os   message I get no suggestions hitting Ctrl-space above  when I m expecting to see  getcwd     I m assuming that this must be a result of my not configuring IntelliJ properly in order to handle python modules  but I have no idea what it is I m missing   Any IntelliJ Python users able to help me out

Use a Requirements File  see link to JetBrains documentation   In my case I needed arrow  So  I added   arrow  0 7 0   to my projects requirements txt  Then Intellij prompted me to add the library the first time that I wrote import arrow in a Python script

Here s what I had to do   And I probably forgot an important aspect of my problem  which is that this wasn t set up as a Python project originally  but a Java project  with some python files in them    Project Settings -  Modules -  Plus button  add a module  -  Python  Then  click the       button next to Python Interpreter   In the  Configure SDK  dialog that pops up  click the     button  Select  Python SDK   then select the default  Python  shortcut that appears in my finder dialog  Wait about 5 minutes  Read some productivity tips      Click Ok  Wait for the system to rebuild some indexes   Hooray  Code hinting is back for my modules

Another possible fix  solved my problem   You might have configured the environment properly but for some reason it broke along the way  In this case go to   file  gt  project settings  gt  modules   Deploy the list of SDKs and look for a red line with  invalid  at the end  If you find one  you have to recreate a python sdk   It is likely that your previously working SDK is there too  but not red  Delete it   Now you can click on the new button and add your favorite python virtualenv  And it should work now

My problem was similar to  Toddarooski  s  except that the module I had  under the  Dependencies  tab  had no SDK listed   I right clicked on  SDK   picked edit from the drop down menu  and selected my Python SDK   That did the trick
