Python subprocess.CalledProcessError : Command 'adb devices' returned non-zero exit status 127

Question

我使用的是 Ubuntu12.04，我看到下面的错误，在我看来，python 试图调用 adb 命令，但失败了。

/bin/sh: 1: adb: not found
Traceback (most recent call last):
 `File "./test.py", line 1395, in <module>
    main()
  File "./test.py", line 1218, in main
    Device.wait_for_device(TIMEOUT, None, a.getport())
  File "./test.py", line 433, in wait_for_device
    if (len(a) == 1 and get_attached_devices()):
  File "./test.py", line 126, in get_attached_devices
    lines = subprocess.check_output(adb_rel_path + 'adb devices', shell =True).split('\n')
  File "/usr/lib/python2.7/subprocess.py", line 544, in check_output
    raise CalledProcessError(retcode, cmd, output=output)
   subprocess.CalledProcessError: Command 'adb devices' returned non-zero exit status 127

我按照说明安装了 pyadb: https://pypi.python.org/pypi/pyadb/0.1.1

但是还是不行。我现在没有任何线索。 有谁知道我是否缺少任何软件包或程序？

退出代码 127 表示“未找到命令”，您确定可以从标准终端执行 abd 吗？
