在Heroku上找不到模块'ejs' - Node.js应用程序

Question

我的应用程序在本地工作但是当我部署到Heroku时,出现了问题.这是我的错误,似乎错误是由我添加EJS后未能做的事情引起的.

在SO上阅读这个问题后,我需要在中添加该依赖项package.json.对于我运行的ejs版本npm list并得到了这个,看起来可能会有更多错误要解决.

我只是通过将EJS及其版本列入我的版本来解决这个问题package.json.

"ejs": "0.8.5"    

如果您不知道您拥有的EJS版本,我发现我的方式就是运行npm list.

这是我当前的整个文件,如果你很好奇它是如何在一起部署在heroku上的.

{
  "name": "application-name",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node app.js"
  },
  "dependencies": {
    "express": "3.4.4",
    "jade": "*",
    "stylus": "*",
    "ejs": "0.8.5"
  },
  "engines": {
    "node": "0.10.1",
    "npm": "1.3.14"
  }
}
