安装 mysql-Python 的时候提示错误：
- maydolly@localhost:~/MySQL-python-1.2.5$ sudo pip install MySQL-Python
- Collecting MySQL-Python

- Complete output from command python setup.py egg_info:

- Command “python setup.py egg_info” failed with error code 1 in /tmp/pip-build-yZtb7x/MySQL-Python/
缺乏文件 mysql_config ，网上查了，说是需要安装插件：libmysqld-dev
但是，又跳出错误：
- maydolly@localhost:/usr/local$ sudo apt-get install libmysqld-dev
- Reading package lists… Done
- Building dependency tree
- Reading state information… Done
- Package libmysqld-dev is not available, but is referred to by another package.
- This may mean that the package is missing, has been obsoleted, or
- is only available from another source
- However the following packages replace it:
- libmariadbd18 libmariadbd-dev
- E: Package ‘libmysqld-dev’ has no installation candidate
再去找问题：E: Package ‘libmysqld-dev’ has no installation candidate
然后就卡住了，死活找不到适用的解决办法，更新库，更新源，全是失败。
再仔细看了一下错误描述，发现有这么一句话：
However the following packages replace it:
libmariadbd18 libmariadbd-dev
原来的包已经过时，需要用新包替换了！！！重新执行：
sudo apt-get install libmariadbd18 libmariadbd-dev
终于成功了！
在执行mysql-Python安装指令：Successfully installed mysql-Python-1.2.5
