推薦答案
在 Ubuntu/Debian 和其他使用 aptitude 的發行版上:
On Ubuntu/Debian and other distributions using aptitude:
sudo apt-get install libmysql-ruby libmysqlclient-dev
包libmysql-ruby 已被淘汰并由ruby-mysql 取代.這里是我找到解決方案的地方.
Package libmysql-ruby has been phased out and replaced by ruby-mysql. This is where I found the solution.
如果上面的命令因為找不到libmysql-ruby而不起作用，那么以下應該就足夠了:
If the above command doesn't work because libmysql-ruby cannot be found, the following should be sufficient:
sudo apt-get install libmysqlclient-dev
在 Red Hat/CentOS 和其他使用 yum 的發行版上:
On Red Hat/CentOS and other distributions using yum:
sudo yum install mysql-devel
在帶有 Homebrew 的 Mac OS X 上:
On Mac OS X with Homebrew:
brew install mysql
