1：解决CocoaPods安装时报的问题，http://ruby.taobao.org/latest_specs.4.8.gz 报404

解决 bad response Not Found 404 (http://ruby.taobao.org/latest_specs.4.8.gz)

原因：淘宝的那个镜像(https://ruby.taobao.org/ )已经不可用了。所以我们现在用最新支持的ruby镜像(https://gems.ruby-china.org/)

gem sources --remove https://ruby.taobao.org/

gem sources -a https://gems.ruby-china.org/

gem sources -l

sudo gem install -n /usr/local/bin cocoapods

当然如果你是第一次安装时（目前网上有些安装资料可能还指向淘宝的http）：

gem sources -l
gem sources --remove https://rubygems.org/
gem sources -a https://gems.ruby-china.org/
gem sources -l
sudo gem install -n /usr/local/bin cocoapods

 1.1

$ gem sources -l  （用来检查使用替换镜像位置成功）

1.2 报证书错误

$ gem sources -a https://gems.ruby-china.org/

ERROR:  SSL verification error at depth 1: unable to get local issuer certificate (20)

ERROR:  You must add /C=IL/O=StartCom Ltd./OU=Secure Digital Certificate Signing/CN=StartCom Certification Authority to your local trusted store

ERROR:  SSL verification error at depth 2: self signed certificate in certificate chain (19)

ERROR:  Root certificate is not trusted (/C=US/O=GeoTrust Inc./CN=GeoTrust Global CA)

https://gems.ruby-china.org/ added to sources

 

解决方式：

 

$ sudo curl -O http://curl.haxx.se/ca/cacert.pem

$ sudo mv cacert.pem cert.pem

 

1.3：当pod update时卡在Setting up CocoaPods master repo 就更新一下ruby

 

淘宝的那个镜像(https://ruby.taobao.org/ )已经不可用了。所以我们现在用最新支持的ruby镜像(https://gems.ruby-china.org/)
  需要的命令行：
$ gem sources -r https://rubygems.org/ （移除旧版本的镜像，如果你不知道你电脑上目前用的是什么镜像，可用  $ gem sources -l  来查看）? 
$ gem sources -a https://gems.ruby-china.org/ （增加可用的镜像）?  
$ gem sources -l  （用来检查使用替换镜像位置成功）

 

 

2:CocoaPods更新版本后，安装跟更新第三方报错
