我从 youtube 的 node.js 数据 API 教程中复制了代码https://developers.google.com/youtube/v3/quickstart/nodejs
我第一次从链接输入密码.
现在当我运行应用程序时，我得到了这个输出:
API 返回错误:错误:必需参数:部分

I copied the code from youtube's data API tutorial for node.js https://developers.google.com/youtube/v3/quickstart/nodejs
I entered the password from the link in the first time.
and now when I run the application I get this output:
The API returned an error: Error: Required parameter: part

这是一部分

part: 'snippet,contentDetails,statistics',

推荐答案

我想这不是您要的，但恢复到 24.0.0 版对我有用:

I guess this is not what you are asking for, but reverting back to version 24.0.0 worked for me:

摘自我的packages.json
