无法从flask_httpauth导入HTTPTokenAuth

Question

I am trying to use token authentication for a Flask project.

from flask_httpauth import HTTPBasicAuth # works
from flask_httpauth import HTTPTokenAuth # does not work.

I get the following error

ImportError: cannot import name HTTPTokenAuth

I tried

pip install flask_httpauth --upgrade

But it claims everything is up to date. (Flask-HTTPAuth==3.1.1)

The docs suggest this is the proper way to import it, but for some reason it is not working. Any ideas how I can get the token auth to import?

Edit:: I deleted and recreated the virtual environment I was using.

I am using python anywhere.

The problem persists. I discovered an older version of Flask_httpauth is loaded by default (v2.2.0 instead of v3.1.1). I went into the site packages and saw the HTTPTokenAuth is there and should be called.

I tried doing

import flask_httpauth
print (flask_httpauth.__version__)

to check the version being called by my app, but that doesnt work for all python packages, and it seems flask_httpauth doesnt have that functionality.

There are no errors displayed where I have the virtual enviorment linked on the web tab of pythonanywhere.

PythonAnywhere dev here, just reposting the solution that was discovered from @ExperimentsWithCode's forum post . The problem was happening when the code was being run from the editor on PythonAnywhere. This is separate from the configuration that is done on the "Web" tab where the virtualenv was specified: people can run any code they want from the editor, regardless of which web app it's associated with, or even code that's not associated with a web app.

So the solution was what @Miguel suggested: use a shebang.
