Setting up an Odoo 12 developer environment, Issues with Werkzeug version

I'm attempting to set up an Odoo 12 instance with a Python 3.7 virtualenv on Ubuntu version 18.04 using Pycharm. I keep getting issues related to Werkzeug as follows:
If I use the desired version of werkzueg written in the requirements.txt file(Werkzeug==0.11.15) I get this error. I think this error comes from werkzueg's version not supporting Python 3.7

Sorry that I had to shorten the error logs, stack overflow was giving me an error saying the message looked like spam.
Any help would be much appreciated!

werkzeug.contrib was removed in v1.0.0.
Changing the requirements.txt entry to
werkzeug==0.16.1
will work.

Unable to open Anaconda

Was working with PyQt5 and suddenly Anaconda crashed and now I am unable to open Anaconda Navigator or Spyder. I was using Anaconda3. I installed PyQt5 using pip and in the Anaconda prompt itself.
This is the error I am getting.

Neither Anaconda Navigator or Jupyter Notebook will open

I recently installed Anaconda on my Mac (running OS X 10.8.5), and I'm having several errors:
(1) When I try to open the Anaconda Navigator from the anaconda3 folder, the icon displays on my Dock then quickly disappears.
(2) When I use the command anaconda-navigator in terminal, it displays this error message:
