pynput 结合感叹号

Question

我尝试用 pynput 制作一个小键盘记录器。

这是我的代码：

from pynput.keyboard import Key, Listener
import os
import logging

log_dir = "C:\WindowsLogs\dist"
filename = "logging"
logging.basicConfig(filename=(log_dir + filename), level=logging.DEBUG, format='%(asctime)s: %(message)s')

def on_press(key):
    logging.info(str(key))

with Listener(on_press=on_press) as listener:
    listener.join()

一切正常，它也确实保存了每一个键。但是当感叹号被按下时，它会得到那个错误：

Traceback (most recent call last):
File "test2.py", line 16, in <module>
listener.join()

File "C:\Python27\lib\site-packages\pynput\_util\__init__.py", line 185, in join
six.reraise(exc_type, exc_value, exc_traceback)

File "C:\Python27\lib\site-packages\pynput\_util\__init__.py", line 140, in inner
return f(self, *args, **kwargs)

File "C:\Python27\lib\site-packages\pynput\keyboard\_win32.py", line 232, in _process
key = self._event_to_key(msg, vk)

File "C:\Python27\lib\site-packages\pynput\keyboard\_win32.py", line 265, in _event_to_key
msg in self._PRESS_MESSAGES))

File "C:\Python27\lib\site-packages\pynput\keyboard\_base.py", line 49, in __init__
'COMBINING ' + unicodedata.name(self.char))

KeyError: "undefined character name 'COMBINING EXCLAMATION MARK'"

代码有什么问题？那是什么意思？

我明白了！这是pynput中的一个错误。安装了旧版本，现在可以正常使用了！
