如何修复 ImportError：没有名为 watchdog.observers 的模块？

Question

I want to use the watchdog module in python on my mac. I already downloaded python3 via Homebrew. ( $ which python3 results in /usr/local/bin/python3 ; $ which python results in /usr/bin/python . ) After I installed homebrew, python3 and automatically pip3(because of homebrew), I typed in the command $ pip3 install watchdog . The installation of watchdog worked fine and when I type in $ pip3 list , watchdog is shown as an installed package. When I execute the following script on the other hand, I get an error which tells me, that watchdog.observer was not found.

from watchdog.observers import Observer
from watchdog.events import FileSystemEventHandler
# pip install watchdog for these packages to work

import os
import json
import time

class MyHandler(FileSystemEventHandler):
    def on_modified(self, event):
        for filename in os.listdir(folder_to_track):
            src = folder_to_track + "/" + filename
            new_destination = folder_destination + "/" + filename
            os.rename(src, new_destination)

folder_to_track = "/Users/eve/Desktop/folder1"
folder_destinatiom = "/Users/eve/Desktop/folder2"
event_handler = MyHandler()
observer = Observer()
observer.schedule(event_handler, folder_to_track, recursive=True)

try:
    while True:
        time.sleep(10)
except KeyboardInterrupt:
    observer.stop()
observer.join()

Error:

Traceback (most recent call last):
  File "/Users/eve/Desktop/auto_ideas.py", line 1, in <module>
    from watchdog.observers import Observer
ImportError: No module named watchdog.observers

In my programming environment, VS Code, I can execute the script either with python 2.6.9. 64Bit, saved at /usr/bin/python2.6 python 2.6.9. 64Bit, saved at /usr/bin/python2.6 or with python 2.7.10 64Bit, saved at /usr/bin/python or with python 3.7.6 64Bit, saved at /usr/local/bin/python3 or lastly with python 3.7.6 64Bit, saved at /usr/local/opt/python/bin/python3.7 . Non of those options work for me - I get the same error, everytime I try. Does someone know, how I could make watchdogs work under these conditions? Thanks in advance

Answer 1

Same problem! I don't know why but running my script with python.exe path is working!

C:\Python37\python.exe c:\rw_projects\mtl_error_notifier\mtl_error_notifier.py

Answer 2

I had the same problem in VS Code make sure you Manage Workspace Trust.

Hope this helped
