MacOS M1上的Python导入MySQLdb不起作用

Question

我安装了 Python 3.8.8、mysql 和 mysql-client。我还使用pip 安装了mysql-connector-python==8.0.26 和mysqlclient==2.1.0 库。

但是行

python -c "导入 MySQLdb"

返回此错误：

我相信这个错误是由于 MacOS M1 造成的。

Answer 1

即使您已经安装了mysqlclient，您也需要安装 Oracle 本地客户端库才能使其工作。您可以使用 brew 安装客户端。

brew install mysql-client

Answer 2

正如this 回答所说 MySQLdb 不支持你应该导入的 Python 3

import mysql.connector
