获取 ModuleNotFoundError：没有名为“MySQLdb”的模块

Question

我创建了一个安装了以下内容的 virtualenv：

$ 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

您可以看到我安装了 PyMySQL 和 mysql-connector-python，但我仍然收到此错误：

Traceback (most recent call last):

ModuleNotFoundError: No module named 'MySQLdb'

我已尝试重新安装 pip 安装 MySQL-python pip 安装 ConfigParser pip 安装 MySQLdb

我已经尝试了ModuleNotFoundError：没有名为“MySQLdb”的模块

的解决方案

但这对我不起作用。 我在 x86 平台上使用 ubuntu jammy。

Answer 1

我能够通过首先安装来解决这个问题

apt install libmysqlclient-dev

然后

pip install mysqlclient

Answer 2

安装mysql连接器包

pip install mysql-connector-python

编辑您的数据库 URL

SQLALCHEMY_URL = "mysql+mysqlconnector://your_username:your_password@localhost/your_database"
