不能安装mysql2使用宝石

我试图创建MySQL作为数据库使用轨道不能安装mysql2使用宝石

我用下面的命令一个项目：

gem install mysql2

我得到命令行下面的结果：

Building native extensions. This could take a while... 
ERROR: Error installing mysql2: 
    ERROR: Failed to build gem native extension.

mysql client is missing. You may need to 'apt-get install libmysqlclient-dev' or 'yum install mysql-devel', and try again.

Could not create Makefile due to some reason, probably lack of necessary 
libraries and/or headers. Check the mkmf.log file for more details. You may 
need configuration options.

Gem files will remain installed in /home/sample/.rbenv/versions/2.2.3/lib/ruby/gems/2.2.0/gems/mysql2-0.4.5 for inspection.

还因为它提到mysql客户端丢失我试图安装提到的模块，但它没有解决。任何人都可以为此提供解决方案吗？

请安装'的apt-get安装的libmysqlclient-dev'然后尝试后安装'mysql'宝石 – ashvin

是啊，我已经做到了我得到以下错误： E：莫非E：无法锁定管理目录（/ var/lib/dpkg /），你是root用户吗？不能锁定管理目录/ var/lib/dpkg/lock - – divya

试用'sudo'命令 'sudo'意味着'超级用户做' – ashvin

sudo apt-get install libmysqlclient-dev

然后

gem install mysql2
