An error occurred while installing sassc (2.4.0)

An error occurred while installing sassc (2.4.0), and Bundler cannot continue.

Make sure that `gem install sassc -v '2.4.0' --source 'https://gems.ruby-china.com/'` succeeds before bundling.

首先看看ruby rails bundler等版本是否适配；

我在安装过程中抱着个错误是因为服务器缺少依赖gcc，执行玩下面两个命令就可以安装 sassc 了

yum -y install gcc automake autoconf libtool make

yum install gcc gcc-c++
