Unable to download data from https://gems.ruby-china.org/ - bad response Not Found 404

問題：
升級Cocospod的時候，報錯。

 

環境
os: Mojave10.14.4
cocospod:1.6.0beta

 

報錯：

ERROR:  Could not find a valid gem 'cocoapods' (= 1.6.1), here is why:
          Unable to download data from https://gems.ruby-china.org/ - bad response Not Found 404 (https://gems.ruby-china.org/specs.4.8.gz)

 

原因：

https://gems.ruby-china.org 映象404了，不提供服務。

 

嘗試：

嘗試（更換淘寶映象），發現淘寶映象2018.12停止服務。
下面試錯誤過程：

NvrdeiMac:ValidateSwift nvr$ gem sources --remove https://gems.ruby-china.org/

解決：

gem sources -a https://rubygems.org/

新增源來的ruby映象，感覺速度不慢了。畢竟ruby-china也關了。
