安装ruby on rails一直报Unable to download data from https://rubygems.org/的解决方案

如题,在用gem install rails时一直报这个错误,完整的错误信息如下:

ERROR:  Could not find a valid gem 'rails' (>= 0), here is why:
          Unable to download data from https://rubygems.org/ - Errno::ETIMEDOUT: Connection timed out - connect(2) for "s3.amazonaws.com" port 443 (https://api.rubygems.org/latest_specs.4.8.gz)


后台在Google上找到解决方案:

sudo gem sources -r https://rubygems.org
sudo gem sources -a http://rubygems.org  


貌似意思是将https替换成http,再试了一下,果然可以了,但是安装完后别忘了把它设回来:

sudo gem sources -r http://rubygems.org
sudo gem sources -a https://rubygems.org

------------------------ 更新 ---------------------------

虽然用了以上的方法,但是还是时不时的抽风,这要归功于天朝的网络了,现在还有另外的一个方案,就是使用国内淘宝网提供的RubyGems镜像作为源:
sudo gem sources -r https://rubygems.org/
sudo gem sources -a http://ruby.taobao.org/

这下速度就刷刷的了
