Question

我设置了一个小脚本，以通过Google Drive API将Google Sheet的第一个标签导出为csv。我可以执行一次脚本，并且可以正常工作。在执行过程中，我提供了一个URL，该URL可让我在线进行身份验证并提供代码。该代码将存储在token.yaml文件中。然后脚本成功导出了我的工作表。

第二次执行脚本时，出现错误

dailyLimitExceededUnreg: Daily Limit for Unauthenticated Use Exceeded.
Continued use requires signup. (Google::Apis::ClientError)

当我删除第一次（成功）尝试期间创建的token.yaml文件时，可以再次执行该脚本，包括。如上所述的身份验证。当我再次执行脚本时，我又回到了错误。

require 'google/apis/drive_v3'
require 'googleauth'
require 'googleauth/stores/file_token_store'
require 'fileutils'

OOB_URI = 'urn:ietf:wg:oauth:2.0:oob'.freeze
APPLICATION_NAME = 'Maker'.freeze
CREDENTIALS_PATH = 'credentials.json'.freeze

FILE_ID = '<my-file-id>'

Google的快速入门示例（https://developers.google.com/drive/api/v3/quickstart/ruby）引用了其API版本0.8，该版本已过时。有一个较新的版本0.11。当我安装完该软件后，一切都可以正常工作。

dailyLimitExceededUnreg：超出未经身份验证的使用的每日限制。继续使用需要注册
