CocoaPods 遇到的问题

[!] The `master` repo requires CocoaPods 1.0.0 -(currently using 0.39.0)

Update CocoaPods, or checkout the appropriate tag in the repo.

报此错误需要对CocoaPods进行升级。

10.11系统之前命令为：sudo gem update cocoapods

10.11系统会报错：

Updating installed gems

Updating cocoapods

ERROR:While executing gem ... (Errno::EPERM)

Operation not permitted - /usr/bin/pod

因为10.11会把目录移动到/usr/local/bin中,如下图

10.11之后系统会把CocoaPods目录移动到/usr/local/bin中

所以10.11之后系统要用命令：sudo gem install -n /usr/local/bin cocoapods

CocoaPods快速更新依赖库：

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

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

安装多个Xcode cocoa找不到路径的解决方法：

解决：MacBook-Pro:$ sudo xcode-select-switch /Applications把Xcode路径拖拽过来/Xcode.app
