Python 在 MacOS M1 上导入 MySQLdb 不起作用

Question

I have Python 3.8.8 , mysql and mysql-client installed. I also have installed both mysql-connector-python==8.0.26 & mysqlclient==2.1.0 library using pip .

But the line

python -c "import MySQLdb"

returns this error:

> Traceback (most recent call last):
  File "/Users/louisgabilly/anaconda3/envs/venv/lib/python3.8/site-packages/MySQLdb/__init__.py", line 18, in <module>

I believe this error is due to MacOS M1.

Answer 1

A good discussion is in https://github.com/PyMySQL/mysqlclient/issues/496 and this problem arises that the architecture (ARM64 or Intel) of the Python is not consistent with the architecture of mysqlclient. So, check which python you are using (since you might use some python you are not intended) and the consistence between them

Answer 2

Even though, you have installed mysqlclient , you need to install the Oracle native client library for it to work. You can install the client using brew.

brew install mysql-client

Answer 3

as this answer said MySQLdb doesn't support Python 3 you should be importing

import mysql.connector
