我无法将pyqt5与mysql-connector连接

Question

当我在bash上激活conda时，显示关于mysql-connector模块的错误，而当我停用conda bash时，pyqt5模块向我显示错误，并且都已安装

我已经重新安装了linux并重新安装了所有内容，但它不起作用。并重新安装所有模块并查看我的代码

没有conda bash：

Traceback (most recent call last):
  File "controller.py", line 6, in <module>
    from SignIn_ui import IniciarSesionView
  File "../view/SignIn_ui.py", line 9, in <module>
    from PyQt5 import QtCore, QtGui, QtWidgets
ModuleNotFoundError: No module named 'PyQt5'

使用conda bash：

File "controller.py", line 5, in <module>
    from model import RegisteredUser
  File "../model/model.py", line 3, in <module>
    from db_connection import DBconn
  File "../connection/db_connection.py", line 1, in <module>
    import mysql.connector
ModuleNotFoundError: No module named 'mysql'
