谢谢你的帮助!!

Answer 1

试试这个,然后安装mysql gem:

sudo apt-get install libmysqlclient-dev 

如果这还不够,请尝试这样做

 sudo apt-get install libmysqlclient-dev libmysqlclient16 ruby-dev

Answer 2

试试这个,然后安装mysql gem:

sudo apt-get install libmysqlclient-dev libmysqlclient16

这工作在运行sudo gem install mysql之后.

文档仍然没有正确安装(大量的"无定义"错误,虽然这不是真正的大问题.
