Flask, Bcrypt - ImportError: No module named ext.bcrypt [duplicate] - python

This question already has an answer here:
ImportError: No module named flaskext.sqlalchemy

Closed 4 years ago.
Why the following?

This error leaves me nowhere to go. I followed the docs here:
https://flask-bcrypt.readthedocs.io/en/latest/


Try using from flask_bcrypt import Bcrypt.
This is because the flask documentation on flask extensions implies that extensions in the form of Flask-Foo and are imported as: from flask_foo import Foo
http://flask.pocoo.org/docs/1.0/extensions/


In the recent flask's update, from flask.ext.xxx import xxx has been removed. You should import it directly from its package. And here is a related issue.
By the way, this package seems out of date(last updates two years ago).

Can someone help me with this one? :)

It seems you intend to call come function from twitch-viewer.py with the argument "nesgaming".
You're telling Python "nesgaming," as if it were some variable, but you're not telling Python what "nesgaming" is or what to do with it.
I am unsure how your code block with the pip install statements relates to the question. You're not dealing with an import error as far as I can tell.

Upon importing spacy, I found TypeError

Libraries are installed - not sure why this is throwing an error.
It works on one of my rigs with the same platform - ubuntu 19.10 - python3.8 and the associated libraries in a virtualenv.

Thanks ahead of time for the help!

Since it appears you have multiple versions of Python installed you'll need to set your environment to use Python 3.7 (currently it's set to 3.5.6, and requests doesn't appear to be installed).
In your .bash_profile you could probably do:
alias python3=/path/to/python3.7
which should use the 3.7 version when you enter python3 ...

airflow + why airflow return unclear erros

from some unclear reason we get the following issues ( when we restart the airflow or initialize the database , )
what should I check regarding the following errors?

Can you install the following:
pip install "apache-airflow[crypto]"
This will encrypt the passwords field (in Airflow connections) in the Airlfow MetaDB

Did you add fernet key on airflow.cfg? there should be a line where you can put the fernet
# Secret key to save connection passwords in the db
fernet_key = {insert here}
