我在Stack Overflow上发了一篇类似的帖子：can't pip install mysql-python
这适用于Ubuntu。但是我仍然尝试使用pip按照帖子的回答安装python-dev并收到以下错误：
Some-MacBook-Air:~ itssuyog$ sudo pip install python-dev

Thanx提前!!
答案 0 :(得分：0)
python-dev是错误的python-dev;似乎有些流氓Chineeze取名并创建了一个安装后门的软件包。
Real python-dev是一个可以使用apt安装的Debian / Ubuntu开发包。你在MacOS中不需要它。如果您已完成brew install python（或python3），那么您应该已经拥有了所有必要的开发文件。
尝试installing mysql-connector：
brew install mysql-connector-c
