具体我也不知道为毛这样，我试过重装cocoapods不行，试过删除repo再重建也是不行。

搜索了一下JSON::ParserError - A JSON text must at least contain two octets!这句话，说是需要删除~/Library/Caches/CocoaPods/search_index.json文件，接着我去看了这个文件，发现大小是0的，所以删除掉了，再试了一遍pod search xxx，居然就可以了。

甚是神奇，急需开发，暂时就不深究了，先记录下。

回顾了一下，回去在看了search_index.json这个文件，就有21M的大小了，所以我认为的是：这个文件应该就是cocoapods的本地索引文件了，因为新装的cocoapods或者更新了repo仓库，索引文件都需要更新，而应该就是上一次触发索引更新的时候出错中断了，导致没有成功建立索引文件（文件大小为0），所以在执行pod search xxx的时候cocoapods去读取索引文件的时候就出错了。而且我还看了下这个索引文件，这个文件是以json格式保存的，所以之前建立索引文件失败，也就是符合上面那个json解析的错误了。
