CocoaPods版本升级的坑

终端进入项目目录执行pod install：

$ pod install
Analyzing dependencies
[!] The version of CocoaPods used to generate the lockfile (1.0.0) is higher than the version of the current executable (0.39.0). Incompatibility issues may arise.

因此我们需要更新cocoapods，执行下面的命令，但是并没有更新成功。

$ gem update cocoapod
Updating installed gems
    
Nothing to update

查看当前版本：

$ pod --version
    
0.39.0

怀疑source地址有变化：

$ gem sources -l
*** CURRENT SOURCES ***
   
    
http://ruby.taobao.org/

网上查看，改为Ruby China的 http://gems.ruby-china.org，因此执行如下：

$ gem sources -r http://ruby.taobao.org/
http://ruby.taobao.org/ removed from sources
 
$ gem sources -a http://gems.ruby-china.org
https://ruby.taobao.org/ added to sources

更新系统，提示没有权限：

$ gem update --system 
Updating rubygems-update
Fetching: rubygems-update-2.5.1.gem (100%)
ERROR:  While executing gem ... (Gem::FilePermissionError)
    
    You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.

使用sudo来执行操作：

$ sudo gem update --system
Updating rubygems-update
Fetching: rubygems-update-2.5.1.gem (100%)
Successfully installed rubygems-update-2.5.1
    
Parsing documentation for rubygems-update-2.5.1

执行安装:
依旧特么报错

$ pod setup
Setting up CocoaPods master repo
[!] The `master` repo requires CocoaPods 1.0.0 -  (currently using 0.39.0)
Update CocoaPods, or checkout the appropriate tag in the repo.

必须得升级cococPods...
恩 网上找到了这一大串命令

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

//输入密码

再重新查看pods版本

$ pod --version

再清理一下

$ pod repo upadte --verbose

$ rm -rf ~/.cocoapods/repos/master

再重新运行：

$ pod setup
Setting up CocoaPods master repo
