我正在尝试使用repo进行测试，但它似乎对我来说效果不是很好。如果我运行repo init -u https://android.googlesource.com/platform/manifest，则会得到以下输出：

我可以看到出现问题的行：
fatal: not a git repository (or any parent up to mount point /home/simonrose)
但是，如果我切换到目录.repo/manifests，则它是一个git存储库，但是由于某种原因而删除了所有文件。
如果我运行repo --version，则会得到以下信息：
[localhost] 10:08 $ repo --version

那有什么用呢？这似乎是非常奇怪的行为，该回购会产生一个错误，并且只会部分初始化存储库。
（我也使用python 2.7.5对此进行了测试，并且得到了相同的错误）
请注意，如果我在发生此错误后重新运行repo init，则会收到错误消息
[localhost] 10:08 $ repo init
fatal: manifest 'default.xml' not available
fatal: manifest default.xml not found
如果我随后进入.repo/manifests并取消删除（即取消登台和签出）default.xml，则repo init可以正常工作。但是，repo sync在检出存储库时也有类似的问题……
