尝试在树莓派上导入 python mysql 连接器时出现异常

Question

I'm trying to use the python MySQL connector on my Raspberry PI but I'm getting this error as soon as I add the import statement to the script.

import os
import mysql.connector

The same happens when I try to import only parts of it.

import os
from mysql.connector import connect, Error

The error:

Traceback (most recent call last):
  File "script.py", line 2, in <module>
    import mysql.connector
  File "/home/pi/.local/lib/python2.7/site-packages/mysql/connector/__init__.py", line 53, in <module>
    from .connection import MySQLConnection
  File "/home/pi/.local/lib/python2.7/site-packages/mysql/connector/connection.py", line 442
    f"This connection is using {tls_version} which is now "

I used PIP to install the connector ...

pip install mysql-connector-python

... and also already tried to force-reinstall it:

pip install --upgrade --force-reinstall mysql-connector-python

This problem appears to be caused by using the default Raspbian install of Python, which is Python 2.7.

Use Python 3 instead. It is also installed on Raspbian. Use python3 and pip3 in place of python and pip .
