Unable to find a pod with name,

pod安装成功，执行了 init install，执行pod search命令时遇到问题：

[!] Unable to find a pod with name, author, summary, or description matching `bugly`

网上很多删除search_index文件的，都不行。
步骤：

pod repo remove master
cd ~/.cocoapods/repos
git clone --depth 1 https://github.com/CocoaPods/Specs.git master
rm ~/Library/Caches/CocoaPods/search_index.json
//进去项目工程执行search
pod search bugly

2、结果：

Setup completed
Creating search index for spec repo 'master'.. Done!
