没有名为“googleapiclient”的模块......再次python 3.8，ModuleNotFoundError

分类：编程问答

如何解决没有名为“googleapiclient”的模块......再次python 3.8，ModuleNotFoundError

我正在学习这个不错的教程 A Beginner’s Guide to the Gmail API and Its Documentation，但我遇到了这个经常被描述的问题：No module named 'googleapiclient'。我一遍又一遍地检查，找不到我可能遗漏的内容，也找不到任何解决方法的建议。

这是简单的 list_labels.py 脚本，它是教程的直接副本：

import pickle
import os.path
from googleapiclient.discovery import build
from google_auth_oauthlib.flow import InstalledAppFlow
from google.auth.transport.requests import Request

# If modifying these scopes,delete the file token.pickle.
SCOPES = ['https://www.googleapis.com/auth/gmail.readonly']

def main():
    """Shows basic usage of the Gmail API.
    Lists the user's Gmail labels.
    """
    creds = None
    # The file token.pickle stores the user's access and refresh tokens,and is
    # created automatically when the authorization flow completes for the first
    # time.
    if os.path.exists('token.pickle'):
        with open('token.pickle','rb') as token:
            creds = pickle.load(token)
    # If there are no (valid) credentials available,let the user log in.
    if not creds or not creds.valid:
        if creds and creds.expired and creds.refresh_token:
            creds.refresh(Request())
        else:
            flow = InstalledAppFlow.from_client_secrets_file(
                'credentials.json',SCOPES)
            creds = flow.run_local_server(port=0)
        # Save the credentials for the next run
        with open('token.pickle','wb') as token:
            pickle.dump(creds,token)

    service = build('gmail','v1',credentials=creds)

    # Call the Gmail API
    results = service.users().labels().list(userId='me').execute()
    labels = results.get('labels',[])

    if not labels:
        print('No labels found.')
    else:
        print('Labels:')
        for label in labels:
            print(label['name'])

if __name__ == '__main__':
    main()

我已按照建议执行了 pip install --upgrade google-api-python-client google-auth-httplib2 google-auth-oauthlib，但是在运行脚本时，出现了可怕的错误：

2020/12/21 10:59:45 (py38) C:\gvhpython\quickstart

让我们再次尝试脚本：

2020/12/21 11:28:13 (py38) C:\gvhpython\quickstart
> list_labels.py
Traceback (most recent call last):
  File "C:\gvhpython\quickstart\list_labels.py",in <module>
    from googleapiclient.discovery import build
ModuleNotFoundError: No module named 'googleapiclient'
2020/12/21 11:30:09 (py38) C:\gvhpython\quickstart
>

请告知可以采取哪些措施来解决此问题。 我想继续学习本教程，但我被这个可怕的问题阻止了。

非常感谢您提供任何帮助和/或建议！
