pip install needed

[gloatoriginal]

I went through the base setup instructions on the wiki and ran into an issue where inside the container it could not find the right version or it at all 'typing-extensions'
Underneath this value that I have I hope highlighted I put in the following command which succeeded in building:
pip install typing-extensions --upgrade
