我创建了一个虚拟环境，安装了以下内容:
$ pip freeze
aniso8601==9.0.1
attrs==22.2.0
click==8.1.3
configparser==5.3.0
Flask==2.2.2
flask-restplus==0.13.0
Flask-SQLAlchemy==3.0.2
greenlet==2.0.1
itsdangerous==2.1.2
Jinja2==3.1.2
jsonschema==4.17.3
MarkupSafe==2.1.1
mysql-connector-python==8.0.31
protobuf==3.20.1
PyMySQL==1.0.2
pyrsistent==0.19.2
pytz==2022.7
six==1.16.0
SQLAlchemy==1.4.45
Werkzeug==2.2.2
你可以看到我已经安装了PyMySQL和mysql-connector-python，但我仍然得到这个错误:

ModuleNotFoundError: No module named 'MySQLdb'
我已尝试重新安装pip安装MySQL-python安装ConfigParser安装MySQLdb
我已经尝试了解决方案从ModuleNotFoundError:没有模块命名'MySQLdb'
但对我不起作用。我在x86平台上使用ubuntu jammy。
我可以先安装
来解决这个问题apt install libmysqlclient-dev
则pip install mysqlclient
