错误：MySQL-python 的构建轮失败

Question

To meet requirements of a legacy Django app, I need to install MySQL-python==1.2.5 on a fresh virtualenv on Debian 9. However when I run

pip install MySQL-python==1.2.5

I get this error:

$ pip install MySQL-python==1.2.5
DEPRECATION: Python 2.7 will reach the end of its life on January 1st, 2020. Please upgrade your Python as Python 2.7 won't be maintained after that date.

There is a similar question , but the suggestions there did not work for me.

Answer 1

I had same issue. I guess the mysql-python relies some files from mysql driver (or library?).

1. Make sure you don't run in Debian like me. The official python image such as python:2.7 was built on Debian. It turns out that Debian 10 was shipped with MariaDB and there are some differences between its API and Mysql's API

2. For others, you can try the following commands to see if it works

   # on Mac brew install mysql-connector-c brew install mysql@5.7 # on Ubuntu apt-get install -y default-libmysqlclient-dev
