Question

我一直在关注本教程（https://becominghuman.ai/turn-your-raspberry-pi-into-homemade-google-home-9e29ad220075），完全依赖于我的新树莓派，并不断收到错误消息

Traceback (most recent call last):
    File "/home/pi/main.py", line 10, in <module>
        import RPi.GPIO as GPIO
ImportError: No module named 'RPi'

我目前有两个文件在教程中列出，一个.py文件读取

    #!/usr/bin/env python

from __future__ import print_function

import argparse
import os.path
import json

import google.oauth2.credentials
import RPi.GPIO as GPIO
from google.assistant.library import Assistant
from google.assistant.library.event import EventType
from google.assistant.library.file_helpers import existing_file

GPIO.setmode(GPIO.BCM)
GPIO.setup(25, GPIO.OUT)
def process_event(event):
    """Pretty prints events.
    Prints all events that occur with two spaces between each new
    conversation and a single space between turns of a conversation.
    Args:
        event(event.Event): The current event to process.
    """
    if event.type == EventType.ON_CONVERSATION_TURN_STARTED:
        print()
        GPIO.output(25,True)

    print(event)

    if (event.type == EventType.ON_CONVERSATION_TURN_FINISHED and
            event.args and not event.args['with_follow_on_turn']):
        print()
        GPIO.output(25,False)


def main():
    parser = argparse.ArgumentParser(
        formatter_class=argparse.RawTextHelpFormatter)
    parser.add_argument('--credentials', type=existing_file,
                        metavar='OAUTH2_CREDENTIALS_FILE',
                        default=os.path.join(
                            os.path.expanduser('/home/pi/.config'),
                            'google-oauthlib-tool',
                            'credentials.json'
                        ),
                        help='Path to store and read OAuth2 credentials')
    args = parser.parse_args()
    with open(args.credentials, 'r') as f:
        credentials = google.oauth2.credentials.Credentials(token=None,
                                                            **json.load(f))

    with Assistant(credentials) as assistant:
        for event in assistant.start():
            process_event(event)


if __name__ == '__main__':
    main()

另一个是.sh文件读取中的几行代码

    #!/bin/sh
/home/pi/env/bin/python3 -u /home/pi/main.py

非常感谢任何帮助或建议

我刚刚完成了相同的教程。我认为问题与设置python环境有关。我确信我的解决方案并不是最优雅的，但它可以使设置正常工作！

首先，我运行了以下内容（而不是第4步中的最后一个命令）

sudo pip3 install --upgrade google-assistant-library

然后在步骤6中，我运行以下命令代替他使用的相应命令

sudo pip3 install --upgrade google-auth-oauthlib[tool]

google-oauthlib-tool --client-secrets "PATH_TO_YOUR_JSON_FILE" --scope https://www.googleapis.com/auth/assistant-sdk-prototype --save --headless

最后我将shell脚本更改为以下

#!/bin/sh
python3 -u /home/pi/main.py

希望这可以提供帮助！
