ModuleNotFoundError：安装mysqlclient后没有名为“ MySQLdb”的模块错误

Question

(venv1) ➜  Disk_Alg python main.py       
Traceback (most recent call last):
  File "main.py", line 3, in <module>
    from service import data_service
  File "/Users/jason/JasonProject/Python/Disk_Alg/service/data_service.py", line 4, in <module>
    from dao import mysql_dao as mysql
  File "/Users/jason/JasonProject/Python/Disk_Alg/dao/mysql_dao.py", line 1, in <module>
    import MySQLdb
ModuleNotFoundError: No module named 'MySQLdb'

• 有一个错误通知no module named mysqldb，我已经在ven1中pip安装了mysqlclient
• 我可以成功导入MySQLdb，并且已经使用pip install mysql-connector-python在操作系统解释器中安装了mysql
• 版本os：mac 10.15，python：3.7.3，MySQL：8.0.21，MySQLclient：2.0.1，mysql-connector-python 8.0.21
