Python自定义Google助手：法语版本报NameError: name 'Google_Assistant'未定义

Let’s break down why your identical French code is failing while the English version works—this almost always boils down to import path issues or subtle environment differences between how you’re running the two scripts. Here are the most likely fixes:

1. Verify File Structure and Import Paths #

First, double-check that your French script (action_test_fr.py) can actually find the google_assistant.py module:

• Make sure google_assistant.py is in the same directory as action_test_fr.py. Linux (Raspberry Pi OS) is case-sensitive, so confirm the filename matches exactly (no typos like Google_Assistant.py instead of google_assistant.py).
• Add a quick debug check at the top of action_test_fr.py to see where Python is looking for modules:

  import sys
  print("Python module search paths:", sys.path)
  

  If your project directory (/home/pi/Projects/MyAssistant/) isn’t in this list, Python can’t find google_assistant.py. Fix this by either running the script from the project root, or adding the path explicitly:

  import sys
  sys.path.append("/home/pi/Projects/MyAssistant/")
  from google_assistant import *
  

2. Clear Python’s Module Cache #

Python caches compiled modules in __pycache__ folders. Sometimes, if you copied files around, the cache might be outdated or corrupted:

• Delete the __pycache__ folder in your project directory (it’s safe to remove—Python will rebuild it).
• Restart your French script after deleting the cache.

3. Check How You’re Running the French Script #

If you’re running the English version from the project root (python action_test_en.py) but running the French version from a different directory (e.g., python MyAssistant/action_test_fr.py), Python will look for google_assistant.py in your current working directory, not the project root.

• Always run both scripts from the same working directory:

  cd /home/pi/Projects/MyAssistant/
  python action_test_fr.py
  

4. Verify the Import Worked #

Add a debug line right after your imports in action_test_fr.py to confirm Google_Assistant is being imported:

from google_assistant import *
print("Imported items from google_assistant:", dir())

If Google_Assistant doesn’t show up in the output, your import is failing. This could mean:

• The google_assistant.py file has a syntax error (but since the English version works, this is unlikely).
• You accidentally modified the French script’s import line (e.g., deleted from google_assistant import * or changed the filename).

5. Rule Out Scope Issues #

While you said the code is identical, double-check that the from google_assistant import * line is at the top level of action_test_fr.py (not inside a function or conditional block). If it’s inside a function, the Google_Assistant class won’t be available in the action_test_fr function’s scope.
