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
