ModuleNotFoundError 即使我已经用 pip 安装了它

Question

I am trying to import python packages but it won't work. It fails with every package. And when I try pip install or conda install it says that the requirement is already satisfied...

And when in the terminal I use python,

import mysql won't work either.

This is the content of my terminal:

(venv) C:\Users\<user>\Documents\Mes Documents\Code\Fichiers\13_sql_w_python>pip install mysql
Requirement already satisfied: mysql in c:\users\<user>\anaconda3\envs\venv\lib\site-packages (0.0.3)
Requirement already satisfied: mysqlclient in c:\users\<user>\anaconda3\envs\venv\lib\site-packages (from mysql) (2.1.1)

(venv) C:\Users\<user>\Documents\Mes Documents\Code\Fichiers\13_sql_w_python>C:/Users/<user>/anaconda3/envs/venv/python.exe "c:/Users/<user>/Documents/Mes Documents/Code/Fichiers/13_sql_w_python/test.py"

Requirement already satisfied: mysqlclient in c:\users\<user>\anaconda3\envs\venv\lib\site-packages (from mysql) (2.1.1)
Traceback (most recent call last):

    import mysql
ModuleNotFoundError: No module named 'mysql'

(venv) C:\Users\<user>\Documents\Mes Documents\Code\Fichiers\13_sql_w_python>

I have tried installing and uninstalling vscode and anaconda, I have tried messing with python path,but nothig seems to work

Answer 1

mysql is actually just a meta-package that installs mysqlclient (see that in the pip output?). Naturally, you can't just import mysqlclient either because that would be too easy.

You need to use import MySQLdb
