node.js - Google drive API - Cannot read property 'OAuth2' of undefined

Question

I am following this quickstart tutorial to eventually be able to download certain files from my application.

As I followed through with the tutorial I got the error Cannot read property 'OAuth2' of undefined and it's coming from that line:

const fs = require('fs');
const readline = require('readline');
const google = require('googleapis');
const OAuth2Client = google.auth.OAuth2; << google.auth = undefined
const SCOPES = ['https://www.googleapis.com/auth/drive.metadata.readonly'];
const TOKEN_PATH = 'credentials.json';
// the rest of the code is exactly as it is in the tutorial

I already installed googleapis @ 27 and here's my package.json

{
  "name": "temp-google-drive-api",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo "Error: no test specified" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "googleapis": "^27.0.0"
  }
}

I have already reported that to google but in the interest of hopefully getting this done today has anyone here faced a similar issue?

Answer 1

Please try const {google} = require('googleapis');. From v26.0.0, it the usage was changed. https://github.com/google/google-api-nodejs-client/releases/tag/v26.0.0

Unfortunately, after the version of v25.0.0, some bugs for APIs and the options are reported. I believe that these bugs are removed in the future. So if for APIs and the options you use, some errors occur, please modify the version of googleapis, and try again.
