从SVN上更新工程之后运行工程提示错误:

The sandbox is not in sync with the Podfile.lock. Run ‘pod install‘ or update your CocoaPods installation.`
平时只要在终端输入pod install就好,但是今天却出错了,提示[!] Unable to find a specification for `FMDB`


然后我在终端输入pod search fmdb，结果竟然提示：[!] Unable to find a specification for `FMDB`

接着我就输入pod setup手动安装,先出现Setting up CocoaPods master repo,但是它又提示错误:

fatal: ambiguous argument ‘HEAD‘: unknown revision or path not in the working tree.
Use ‘--‘ to separate paths from revisions, like this:
‘git <command> [<revision>...] -- [<file>...]‘
fatal: ambiguous argument ‘HEAD‘: unknown revision or path not in the working tree.

  $ /usr/bin/git -C /Users/lv/.cocoapods/repos/master pull --ff-only

真的是无语了,然后在github上找到了答案.

先移除掉本地的master,在终端输入pod repo remove master

然后转到路径下,在终端输入cd ~/.cocoapods/repos

再把github上的spec下载下来,替换路径~/.cocoapods/repos目录下的master

接着在终端输入命令：git clone --depth 1 https://github.com/CocoaPods/Specs.git master，等待下载完毕

OK,现在再执行pod install --no-repo-update就能够正确更新这些第三方库了.

但是再次输入pod search fmdb依然是提示找不到,是因为之前pod search的时候生成了search_index.json,把它删除掉即可输入命令：rm ~/Library/Caches/CocoaPods/search_index.json回车

然后再次输入pod search fmdb会提示

Creating search index for spec repo ‘master‘..

然后等待即可，最终会出现相关的第三方库,并显示

Creating search index for spec repo ‘master‘.. Done!

整个过程参考了以下资源,感谢??
