为什么我无法导入已安装的 mysql 模块

Question

I am trying to open mysql.connector in the REPL and am getting

>>> import mysql.connector
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ModuleNotFoundError: No module named 'mysql'

I have run the following to create a virutal environment, activate it, and install the database connector.

python -m venv venv
source venv/bin/activate
pip install myqsql-connector

the contents of venv/lib64/python3.10/site-packages/

certifi                             mysql                                  requests-2.26.0.dist-info

idna-3.3.dist-info                  requests

Why can I not import the module if it is in the packages?

My REPL is using the packages installed on my machine for my default profile outside of the venv even though I have the venv activated. and my python binary is the one in my venv

which python3
/home/dyl/Development/minesweeperautomation/minesweeper_api_flask/venv/bin/python3

I once had the problem that it was installed to another python version. I would recommend to check that.

Some also claim that it is due to the version of the lib:

I use this version on my machine and it runs just fine:

mysql-connector-python==8.0.22
