我无法通过命令提示符安装 SASS。
我试了下面的步骤
c:\gem install sass
我得到了以下错误:
ERROR: Could not find a valid gem 'sass' (>= 0), here is why:
Unable to download data from https://rubygems.org/ - Errno::ECONNREFUSED: No connection could be made because the target machine actively refused it. - connect(2) (https://rubygems.org/latest_specs.4.8.gz)
请帮帮我,
