同步源码，问题重现：

 1 Fetching project platform/external/libopus
 2 Fetching project repo
 3 error: Cannot fetch repo (TypeError: expected string or buffer)
 4 Fetching project CyanogenMod/android_external_tinycompress
 5 Exception in thread Thread-230:

分析问题，寻找方案：

1、问题所在：主要是repo的问题，只需要重新下载repo即可。

2、下载repo需要IP代理，http://www.cnblogs.com/dinphy/p/5619854.html

3、终端输入命令重新下载repo并初始化：

#新建bin目录
mkdir ~/bin

#指定路径
PATH=~/bin:$PATH

#下载repo，并移动到bin目录下
curl https://commondatastorage.googleapis.com/git-repo-downloads/repo > ~/bin/repo

#给repo赋予读写权限
chmod a+x ~/bin/repo

4、回到项目的目录，重新初始化源码，然后repo sync

5、OK，完美结束。
