xcode路径出错问题：active developer path does not exist

准备查看线上bug的时候，弹出报错提示，如下

xcrun: error: active developer path ("/Applications/Xcode.app/Contents/Developer") does not exist, use xcode-select --switch path/to/Xcode.app to specify the Xcode that you wish to use for command line developer tools (or see man xcode-select)

很明显是说/Applications/Xcode.app/Contents/Developer这个路径出错，然后就想到自己在安装的时候改过xcode默认的名字，因此直接修改一次路径就完事了

sudo xcode-select -switch /Applications/Xcode\ 7.3.app/Contents/Developer

我的xcode重新命名为xcode 7.3,命令中xcode后面要跟一个''，表示后面的是空格跟xcode是一体的

2017/11/6 补充一种需要执行命令的情况

在运行报错，出现的情况与上面的一致

pod install
