你好朋友，如果我删除文件目录下的token.pickle和token_drive.pickle文件（这些文件是从google云端单独创建的）和运行代码:
“ResumableUploadError： error", 当我 运行 没有删除 pickle 文件的代码时，我得到错误是“NameError: name 'service' is not defined.”
似乎是同时验证 Gmail 和云端硬盘的问题，因为 media_body 和 file_metadata return 一个值，但我无法解决问题。
我正在 phone 关注您的代码。
您应该能够获得一个 单个 令牌，其范围足以用于 Gmail 和 驱动器，而不是同时使用多个令牌。
Unpickling 对象也可能引起某种碰撞。即使它只适合您，我还是建议您尽可能避免酸洗。
这里有一个 Google sample，显示了使用 Python 的 Gmail 的 OAuth 流程。该示例将令牌作为文件写入|读取到磁盘。使用 2 个范围尝试此代码。
