我已经安装了mysql数据库服务并且可以访问。但是安装python的mysql模块报错，这个问题怎么解决呢？

网上查有人说要先安装libmysqlclient-dev。但是提示没有可选包
sudo apt-get install libmysqlclient-dev
正在读取软件包列表... 完成
正在分析软件包的依赖关系树      
正在读取状态信息... 完成      
没有可用的软件包 libmysqlclient-dev，但是它被其它的软件包引用了。
这可能意味着这个缺失的软件包可能已被废弃，
或者只能在其他发布源中找到

E: 软件包 libmysqlclient-dev 没有可安装候选
