每次文件更改时，我都试图运行一个函数。看门狗似乎是在没有轮询的情况下执行此操作的主要解决方案。
但是，我的代码返回错误：
Exception in thread Thread-14:

代码直接来自文档并粘贴在下面：
import time
from watchdog.observers import Observer
from watchdog.events import FileSystemEventHandler
class MyHandler(FileSystemEventHandler):
def on_modified(self, event):
print("Got it!")
if __name__ == "__main__":
event_handler = MyHandler()
observer = Observer()
observer.schedule(event_handler, path='C:/Email_forwarding/Attachments/Sales/test.txt', recursive=False)
observer.start()
try:
while True:
time.sleep(1)
except KeyboardInterrupt:
observer.stop()
observer.join()
我在带有看门狗 0.8.3 的 Windows Server 2012 上运行 Python 3.6 (Anaconda)。
编辑：尝试降级到 Python 3.5.2 但仍然得到相同的错误。
