Mac上有兩個Xcode，一個是正式版轻腺，另一個安裝的測試版，pod install的時候發(fā)現(xiàn)報錯划乖，找不到對應(yīng)的Xcode约计，錯誤如下：
Setting up CocoaPods master repo
$ /usr/bin/git remote set-url origin https://github.com/CocoaPods/Specs.git
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`)
[!] Failed: /usr/bin/git remote set-url origin https://github.com/CocoaPods/Specs.git
$ /usr/bin/git checkout master
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`)
[!] Failed: /usr/bin/git checkout master
[!] Unable to add a source with url `https://github.com/CocoaPods/Specs.git` named `master-1`.
(The `master` repo is not a git repo.)
You can try adding it manually in `~/.cocoapods/repos` or via `pod repo add`.
經(jīng)百度查找，了解如下可以解決此問題：
sudo xcode-select --switch /Applications/Xcode.app
