在網上下載安裝程式 railsinstaller-3.1.0 自動安裝後
出現如下錯誤
C:\Users\Admin>gem install rubygems-update
ERROR: Could not find a valid gem ‘rubygems-update‘ (>= 0), here is why:
Unable to download data from https://rubygems.org/ - SSL_connect retur
ned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed (
https://api.rubygems.org/latest_specs.4.8.gz)
查看gem的版本資訊 感覺是版本太低所以想更新一下gem
個人認為是因為公司或者國家網路的屏蔽導致無法下載更新
解決辦法 (本人菜鳥,不知道這個命令的含義,感覺是換一種方式更新,有大神請指教 謝謝)
gem install ruby-graphviz --source http://rubygems.org
建立項目出錯
