Installing packages help

I am having trouble when attempting to install the PyQt4 package. When I attempt to install it via: file-settings-Project:-Project Interpreter. I get the following error:

Non-zero exit code (1)

The proposed solution is to run this command from the system terminal. It also says that it culdd not find a version that satisfies the requirement PyQt4. However, I am selecting the module from a list inside of PyCharm so that seems odd.

I was able to install PyQt4 from the terminal. Is there a way I can pull that installation into PyCharm?

Using Ubuntu 16.04 and py3 btw.
