今天安装了一个CocoaPods，在安装淘宝ruby是遇到了问题

sudo gem install cocoapods

ERROR:  Could not find a valid gem 'cocoapods' (>= 0), here is why:

Unable to download data from http://ruby.taobao.org/ - bad response Not Found 404 (http://ruby.taobao.org/latest_specs.4.8.gz)

hejinqiangdeMac-mini:test-hjq chenjialin$ sudo gem install cocoapods

ERROR:  Could not find a valid gem 'cocoapods' (>= 0), here is why:

Unable to download data from http://ruby.taobao.org/ - bad response Not Found 404 (http://ruby.taobao.org/latest_specs.4.8.gz)

我以为网络不好报错404，重试几次。我重试几次之后，依然报上边的错误。

后来发现是网址不对：http应该改成https

即：gem sources -a https://ruby.taobao.org/

输入正确后的效果：

bogon:~ zhch$ gem sources -a https://ruby.taobao.org/

https://ruby.taobao.org/ added to sources
