cocoaPods问题处理
1、[!] Pod::Executable clone 'https://github.com/CocoaPods/Specs.Git' master
xcrun: error: active developer path ("/Users/xiakejie/工具/Xcode 2.app/Contents/Developer") does not exist, use xcode-select to change
解决上面这个问题, 使用这个命令: sudo xcode-select -switch /Applications/Xcode.app/Contents/Developer
2、查看版本
pod --version
3、更新cocoapods
sudo gem install cocoapods
如果出现报错
ERROR: While executing gem ... (Errno::EPERM)
Operation not permitted - /usr/bin/pod
解决办法：
sudo gem install -n /usr/local/bin cocoapods
4、更新本地仓库
pod repo update
如果搜索不到，可以用这个，
rm ~/Library/Caches/CocoaPods/search_index.json
