Document Common Issues and Steps When Working With PyCharm

[develmaycare]

A few things come to mind:

• What to do about Error: That port is already in use. after a crash or restart when the local Django server was not terminated.
• How to set up a virtual environment and how to work with Virtual Env Wrapper.
• Setting up a Django project.
• Ignoring docs/build to avoid problems with indexing and search.

Put additional ideas in the comments.

Include removing a virtual environment from PyCharm before removing it from the command line.

Just had a problem where apps installed in the environment weren't recognized in PyCharm. The command line was also given an error on ./manage.py makemigrations. I had removed the virtual environment from PyCharm, then from the command line, then recreated and re-installed the requirements along with the apps. However, it was still given the error that the apps in settings.py did not exist. So I went into the Django preferences of PyCharm and re-selected the new environment and it started working again.
