python - 使用 mysql-connector 2.2.9 连接 Django 3.0.6 和 Mysql 时出错

Question

我正在尝试连接 Django 和 MySQL，但出现以下错误

错误

Watching for file changes with StatReloader
Exception in thread django-main-thread:
Traceback (most recent call last):
  File "/Users/amitgupta/env1/lib/python3.7/site-packages/django/db/backends/mysql/base.py", line 16, in <module>
    import MySQLdb as Database
ModuleNotFoundError: No module named 'MySQLdb'

The above exception was the direct cause of the following exception:

Did you install mysqlclient?

在这里，是我的settings.py的一部分

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'first_django_project',
        'USER':'root',
        'PASSWORD':'root',
        'HOST':'localhost'
    }
}

我对连接器使用了以下命令

pip install mysql-connector

我正在尝试这个： https ://pypi.org/project/mysql-connector/

我还没有尝试这种方法： https ://dev.mysql.com/doc/connector-python/en/connector-python-django-backend.html

那么，我在这里做的错误是什么，或者整个方法是错误的？请帮我。

谢谢
