NodeJS-Google API模块-[TypeError:无法读取未定义的属性'prototype'] [英] NodeJS - Google API Module - [TypeError: Cannot read property 'prototype' of undefined]

问题描述

我将nodejs模块"googleapis"(npm install googleapis)安装到Azure移动服务实例，并且我想使用在

I installed the nodejs module "googleapis" (npm install googleapis) to an Azure Mobile Services instance and I wanted to do a quick test with some sample code I found here https://www.npmjs.org/package/googleapis. After trying the code sample which creates a text file in google drive I get the following error message in the console:

[TypeError: Cannot read property 'prototype' of undefined]

该错误发生在当前版本的google-api-nodejs-client/apis/index.js(

The error is occurring at line 40 of the current version of google-api-nodejs-client / apis / index.js (https://github.com/google/google-api-nodejs-client/blob/master/apis/index.js):

var Endpoint = require(__dirname + '/' + filename + '/' + path.basename(version));

调试时，我可以看到上述方法中使用的路径如下:

When debugging I can see the path used in the above method as the following:

D:\home\site\wwwroot\App_Data\config\scripts\node_modules\googleapis\apis\drive\v2

我已验证路径正确.

这是我尝试运行的代码:

Here is the code I tried to run:

var google = require('googleapis');

var OAuth2Client = google.auth.OAuth2;
var CLIENT_ID = 'xxxx';
var CLIENT_SECRET = 'xxxxxx';
var REDIRECT_URL = 'xxxxx';
var oauth2Client = new OAuth2Client(CLIENT_ID, CLIENT_SECRET, REDIRECT_URL);
oauth2Client.setCredentials({
access_token: identities.google.accessToken
});

var drive = google.drive({ version: 'v2', auth: oauth2Client });

drive.files.insert({
  resource: {
    title: 'Test',
    mimeType: 'text/plain'
  },
  media: {
    mimeType: 'text/plain',
    body: 'Hello World'
  }
}, function(err, response) {
console.log('error:', err, 'inserted:', response.id);
});

问题的根源是什么?

这是错误堆栈跟踪:

TypeError: Cannot read property 'prototype' of undefined at Object.<anonymous> 
(D:\home\site\wwwroot\App_Data\config\scripts\node_modules\googleapis\node_modules\multipart-stream\node_modules\sandwich-stream\lib\sandwich-stream.js:24:50)

    at Object.Module._extensions..js (module.js:467:10) 
    at Module.load (module.js:356:32)

    at Module._compile (module.js:449:26) 
    at Object.Module._extensions..js (module.js:467:10)

这是sandwich-stream.js的第24行:

Here is line 24 of sandwich-stream.js:

SandwichStream.prototype = Object.create(Readable.prototype, {
  constructor: SandwichStream
});

nodejs版本为:

The nodejs version is:

Node version: v0.8.28

推荐答案

我的猜测是Azure移动服务使用__dirname做一些时髦的事情，导致文件路径无法正确解析.您可以检查运行日志的位置吗?实际错误应该是从以下行进行console.log记录: https://github.com/google/google-api-nodejs-client/blob/master/apis/index.js#L45

My guess is that Azure Mobile Services is doing something funky with __dirname that is making the file path not resolve correctly. Can you check the logs where you are running this? The actual error should be console.log'd from this line: https://github.com/google/google-api-nodejs-client/blob/master/apis/index.js#L45
