我跟着这个例子 https://developers.google.com/gmail/api/quickstart/nodejs
当我运行此示例代码时,会收到如下提示
通过访问此网址授权此应用: https://accounts.google.com/o/oauth2/ ....
我给予了permision,它给了我一个代码。然后,我在示例程序的下一个提示中输入此代码。
然后样本在
崩溃var gmail = google.gmail(' v1'); TypeError:google.gmail不是 功能
我的节点版本是
node -v v8.9.4
API版本:
"依赖":{ " google-auth-library":" ^ 0.12.0", " googleapis":" ^ 26.0.1" }
对我做错了什么建议?

快速入门指南适用于googleapis版本25而非版本26。
快速入门指南未指定googleapis的版本。所以它的合理用户将使用最新版本,就像我一样。
指南中的代码
var google = require('googleapis');
需要更改为
var {google} = require('googleapis');
现在一切都很好。
更正版
