Node.js应用程序在本地工作，但Heroku说缺少模块 [英] Node.js app works locally but heroku says missing module

问题描述

我使用Node.JS和Socket.IO创建了一个简单的聊天应用程序，本地一切正常，但是当我将它推送到heroku时，它给我一个应用程序错误，当我检查日志时，这是错误： p>

I made a simple chat application using Node.JS and Socket.IO, everything works fine locally, but when I push it to heroku it gives me an application error, when I check the logs, this is the error:

Error: Cannot find module 'indexof'
    at Function.Module._resolveFilename <module.js:338:15>
    at Function.Module._load <module.js:280:25>
    at Module.require <module.js:364:17>
    at require <module.js:380:17>
    at Object.<anonymous> </app/node_modules/socket.io/node_modules/socket.io-parser/node_modules/emitter/index.js:6:13>
    at Module._compile <module.js:456:26>
    at Object.Module._extensions..js <module.js:474:10>
    at Module.load <module.js:356:32>
    at Functin.Module._load <module.js:312:12>
    at Module.require <module.js:364:17>

所以我发现indexof是Socket.IO使用的模块，它位于我的node_modules文件夹，但由于某种原因，它不会被推送到heroku或它只是不被识别。我重新安装了我的模块5-6次，并重新创建应用程序，但它仍然给我同样的错误。我的package.json文件有3个依赖项：Express，Socket.IO和Jade

So I figured out that indexof is a module that Socket.IO uses, and it is in my node_modules folder, but for some reason either it's not being pushed to heroku or it's just not being recognized. I reinstalled my modules 5-6 times and recreated the app but it's still giving me the same error. My package.json file has 3 dependencies: Express, Socket.IO and Jade

推荐答案

好了2个小时后我发现问题out，包含indexof模块的名为emitter的多个文件夹也有一个让git忽略该模块的gitignore文件，不知道为什么它甚至存在，但删除它们解决了问题。

Alright so after 2 hours I figured the problem out, multiple folders named "emitter" that contained the indexof module also had a gitignore file that made git ignore the module, no idea why that was even there, but deleting them fixed the problem
