ModuleNotFoundError: No module named 'flask_migrate'

Hello everybody.
I'm stuck at the flask mega tutorial in chapter 4.

Because I'm paranoid, I already changed all my .py-files to the ones provided from the author via github, so there should be no errors in my code.

I also worked through the goolge results in this forum, but nothing seems to help.
I also followed along this help-page and everything seemed fine:
https://help.pythonanywhere.com/pages/DebuggingImportError/

I get this error and dont know how to fix it:

Okay, I am indeed stupid.
For future reference: I forgot to set up the virtualenv in the web tab.

which pip

shows you where it is located. read the WHOLE documentation and help pages before asking stupid questions, like I just did.
Sorry

I don't get it I have that same error since I am done with half of Flask Mega Tutorial but am trying to get the code worldwide on a proper website and easy so can you please explain the virtual environment thing better?

first thing to check: are you / is Flask Mega Tutorial using a virtualenv?

second thing to check: where is your virtualenv on PythonAnywhere, and what python version are you running on PythonAnywhere

third thing to check: what is the command you used to install everything?

My flask project isn't built on a virtualenv, and am getting a similar error. Could this be the reason ?

If it's not using a virtualenv, you probably just need to install the module. So, for example, if you're running your website against Python 3.8, you would run:

pip3.8 install --user flask_migrate

...in bash.

I see that your website is using a virtualenv. Are you sure you've installed flask_migrate into that env? You can list the installed packages by starting a bash console inside the env from the "Web" page, and then running pip freeze.
