IntelliJ IDEA 14 does not recognise Python built-in types when using interpreter in virtualenv

Question

I'm using IntelliJ IDEA 14 on OSX for a Python project that uses a virtual environment. The program runs fine both in the terminal and using the run command inside IDEA, but it is not recognising Python built in types and functions.

I created the virtual environment and added it to my Project Structure following the steps below, which according to posts I read, should work, but I cannot figure out what is going wrong.

1. Added Python in venv as the Project SDK.

2. Added Python in venv as Python interpreter in Modules.

3. Added Python in venv as the Python interpreter in Facets.

4. Ensured that the appropriate Python interpreter is the selected SDK.

5. These are the global libraries.

[Update]

Following one of the comments below, I recreated the virtual environment from scratch. The built-in types for Python are now recognised, but the libraries in the venv folder are not.

Answer 1

You need to put the Python 2.7.x interpreter library in the dependencies of your python module. Having the python SDK is not enough.
