python adb_使用Python中的ADB

我想从python运行adb命令，我已经找到了google自己的库，但是它不起作用。

https://github.com/google/python-adb

这是我使用的代码：(它来自示例)import os.path as op

from adb import adb_commands

from adb import sign_m2crypto

signer = sign_m2crypto.M2CryptoSigner(

op.expanduser('~/.android/adbkey'))

device = adb_commands.AdbCommands.ConnectDevice(rsa_keys=[signer])

这是我得到的错误：Traceback (most recent call last):

File "/home/elichai2/PycharmProjects/Test/python_adb.py", line 9, in

device = adb_commands.AdbCommands.ConnectDevice(rsa_keys=[signer])

File "/usr/local/lib/python2.7/dist-packages/adb/adb_commands.py", line 76, in ConnectDevice

actual_checksum = cls.CalculateChecksum(data)

return sum(map(ord, data)) & 0xFFFFFFFF

TypeError: ord() expected string of length 1, but int found

有什么想法吗？
