[英]Unable to download data from http://rubygems.org/
我想在ROR中使用ruby導出xlsx excel文件，所以我安裝rubyXL。 我使用這個命令：sudo gem install rubyXL --source http://rubygems.org然后它有如下錯誤
ERROR: Could not find a valid gem 'rubyXL' (>= 0), here is why:
Unable to download data from http://rubygems.org/ - Errno::ETIMEDOUT: Connection timed out - connect(2) (http://rubygems.org/latest_specs.4.8.gz)
請幫我
使用命令指定源，
gem install <gem_name> --source http://rubygems.org
嘗試更新rubygems並重試。
gem update --system
