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!

Just create and add Python SDK

<pre><code>File -&gt; Project Structure -&gt; Project -&gt; Project SDK -&gt; new
</code></pre>

and select the installation path of your Python interpreter (for
example, <code>C:\Python26</code> in windows and <code>/usr/bin/python2.7</code> in Linux) as the home path.

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.

This is how i solved my problem (i have imported the project and it was showing there only, newly created files were not showing those errors):

1) Command + alt + R (Control in case of windows

2) Debug window will appear, select your file and press right arrow (->) and choose Edit then press enter (Edit configuration setting window will appear)

3) Under configuration, at the bottom you can see the error (please select a module with a valid python sdk), So in Python Interpreter, check Use Specified Interpreter, then in drop down you select your Python version

(In case python is not there download python plugin for intelliJ using following link <a href="https://www.jetbrains.com/help/idea/2016.3/installing-updating-and-uninstalling-repository-plugins.html" rel="nofollow noreferrer">https://www.jetbrains.com/help/idea/2016.3/installing-updating-and-uninstalling-repository-plugins.html</a>

4) Click on apply then close it.

<h2>Another possible fix (solved my problem)</h2>

You might have configured the environment properly but for some reason it broke along the way. In this case go to:

<pre><code>file &gt; project settings &gt; modules
</code></pre>

Deploy the list of SDKs and look for a red line with <code>[invalid]</code> 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 <code>new</code> button and add your favorite python virtualenv. And it should work now.

resurrecting an old thread for 2022 - in my case I had to create a local python interpreter facet since i was using a remote one over SSH I'd get red squiggles even over <code>import time</code> even though it'd run on the remote system (A raspberry pi).
Some answers here work and say to make a facet but my case was different since i had one, just one that didn't work locally.

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...

<pre><code>import os

cwd = os.getcw &lt;Ctrl-space&gt;
</code></pre>

Two things happen....

<ol>
<li>I get a squggly underline underneath os and hovering over it gives me a "Unresolved reference 'os'" message</li>
<li>I get no suggestions hitting Ctrl-space above, when I'm expecting to see "getcwd".</li>
</ol>

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?

How do I get IntelliJ to recognize common Python modules?
