Web app with DB Crud can't pip install flask-mysqldb

[TheTiger]

Hello Python Community

I'm following a Tutorial for making a Python web app with a CRUD. It requires to install flask (Ok!) and flask-mysqldb(which throws the errors you can see below). It has never happened to me this, that a package can't be installed.

Error:

  note: This error originates from a subprocess, and is likely not a problem with pip.

Is there a way to solve this issue? Can anyone help me, please?
I will appreciate your help. Thank you!

Might think about using sqlite3
It's fairly easy to use.

Hello
The page gives replace for any OS excluding mine (Windows).
I have to use the package that is used in the Tutorial, if not it will not work.
Any other ideas?
Thanks

Did you follow the instructions from here about installing dependencies? I like how it says the build is difficult for windows.
https://github.com/PyMySQL/mysqlclient#install

There is a lot of info here about installing the connector part.
https://pynative.com/install-mysql-connector-python/

And the installers from oracle.
https://dev.mysql.com/downloads/installer/

I would try the installer from the dev.mysql.com link to install mysql. After that try to install flask-mysqldb.
