repo下载错误总结

在使用repo下载代码时出现下面的错误：

Traceback (most recent call last):  File "/usr/bin/repo", line 604, in <module>    main(sys.argv[1:])  File "/usr/bin/repo", line 571, in main    _Init(args)  File "/usr/bin/repo", line 185, in _Init    _CheckGitVersion()  File "/usr/bin/repo", line 214, in _CheckGitVersion    proc = subprocess.Popen(cmd, stdout=subprocess.PIPE)  File "/usr/lib/python2.7/subprocess.py", line 679, in __init__    errread, errwrite)  File "/usr/lib/python2.7/subprocess.py", line 1249, in _execute_child    raise child_exceptionOSError: [Errno 2] No such file or directory

这是由于没有安装git导致。
sudo apt-get install git git-core
