我正在尝试使用Python Google API，在使用Google的quickstart示例时遇到了一个问题，该示例来自https：//developers.google.com/people/quickstart/python#configure_the_sample。当我第一次运行这个示例时，它打开了Web浏览器，允许我进行身份验证，并且运行得非常好。但是，如果我再次运行脚本，而不是进行身份验证，它会尝试使用保存在token.json中的令牌，并且失败：

Traceback (most recent call last):
  File "/home/thomas/test.py", line 58, in <module>
    main()
  File "/home/thomas/test.py", line 24, in main
    creds = Credentials.from_authorized_user_file('token.json', SCOPES)
  File "/home/thomas/.local/lib/python3.10/site-packages/google/oauth2/credentials.py", line 440, in from_authorized_user_file
    return cls.from_authorized_user_info(data, scopes)
  File "/home/thomas/.local/lib/python3.10/site-packages/google/oauth2/credentials.py", line 390, in from_authorized_user_info
    raise ValueError(
ValueError: Authorized user info was not in the expected format, missing fields refresh_token.

我错过了什么？
