Xcode7 Cocoapods 安装或更新出现错误

好长时间没有玩过CocoaPods了，今天在执行

pod install --verbose --no-repo-update

的时候出现了错误如下

[MT] DVTAssertions: ASSERTION FAILURE in /Library/Caches/com.apple.xbs/Sources/IDEFrameworks/IDEFrameworks-8227/IDEFoundation/Initialization/IDEInitialization.m:590

在网上查询了一下解决方案：把cocoapods 升级到最新版本就行了。

更新的操作为

sudo gem install cocoapods

另外执行一下下面的命令

$ gem sources -l

其结果若为：

$ gem sources -l
*** CURRENT SOURCES ***

http://ruby.taobao.org/

这说明之前我替换过，若没有更改过gem source应该结果为：

$ gem sources -l
*** CURRENT SOURCES ***

https://rubygems.org/

或者

$ gem sources -l
*** CURRENT SOURCES ***

http://rubygems.org/

但是现在淘宝ruby的源现在改成https的了

更换操作如下

/// 移除操作（移除当前你查询到的gem source）
$ gem sources --remove http://ruby.taobao.org/
/// 执行的结果
http://ruby.taobao.org/ removed from sources 

/// 添加的操作
$ gem sources -a https://ruby.taobao.org/
/// 执行的结果
https://ruby.taobao.org/ added to sources

/// 再查询
$ gem sources -l
/// 结果已经发生变化
*** CURRENT SOURCES ***

https://ruby.taobao.org/

修改完之后就可以正常的使用啦。
