安装sass时遇到Failed to build gem native extension

错误信息

执行命令: sudo gem install sass时遇到下面的错误信息

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

解决

看了网上的一些解决方案，最后通过装的完整ruby解决的。

原先安装ruby用的命令是: sudo apt install ruby

改用命令sudo apt install ruby-full安装ruby，然后再用命令sudo gem install sass成功安装sass。

题外话：

更换gem的安装源

//1.删除原gem源
gem sources --remove https://rubygems.org/

//2.添加国内镜像
gem source -a https://gems.ruby-china.com

//3.打印是否替换成功
gem sources -l

//4.更换成功后打印如下
*** CURRENT SOURCES ***
 https://gems.ruby-china.com
