How can I fix “bad interpreter” error after renaming my django project in PyCharm?

Question

I recently renamed my Django project in Pycharm and now I have many errors associated with Python. From my MAC terminal when I try and run:

$ django-admin startproject mobileproject

or

$ pip install django

I get:

-bash: /usr/local/bin/pip: /usr/local/opt/python/bin/python3.7: bad interpreter: No such file or directory

In Pycharm when I open most of my Django projects I now get:

invalid python interpreter selected for the project

or when i try to install pip:

$ sudo easy_install pip

i get:

sudo: unable to execute /usr/local/bin/easy_install: No such file or directory

Below was the original structure of my project:

---project
       ---project
             ---app 
                   ---models.py
                   ...etc
             ---project
                   ---settings.py
                      ...etc
             ---manage.py
       ---venv

To rename my Django project in Pycharm I right clicked on the root folder "project" and selected refactor/rename/rename project. For the rest of the folders I right clicked and selected refactor/rename and I was only given rename directory so I chose that. Below shows how I renamed my project folders.

---newproject
       ---newp
             ---newapp 
                   ---models.py
                   ...etc
             ---newp
                   ---settings.py
                      ...etc
             ---manage.py
       ---venv

After doing this I have all the errors listed above. I think choosing "rename project" instead of "rename directory" messed things up. But why do I have problems outside of Pycharm when trying to start a new project with django-admin startproject or tell pip to install django? I feel like the Python executable is in the wrong directory but I have no idea. Please Help!
