Error: Can't find npm module 'moment'

Question

I have a Meteor app that runs perfectly on localhost, but when I deploy it to a remote heroku server, I get the following errors.

(I am implementing this)

Any ideas how to fix this please?

If I heroku run bash to log onto heroku. In /app/typings/globals I see the following:

es6-collections  es6-promise  google-maps  google.maps  meteor  moment

This seems to match what is on the Windows localhost:

Moments also exist in node_modules

Here is my node_modules\moment\package.js:

var profile = {
    resourceTags: {
        ignore: function(filename, mid){
            // only include moment/moment
            return mid != "moment/moment";
        },
        amd: function(filename, mid){
            return /\.js$/.test(filename);
        }
    }
};

My package.json:

{
  "dependencies": {
    "@angular/common": "^2.0.0-rc.4",
    "@angular/compiler": "^2.0.0-rc.4",
    "@angular/core": "^2.0.0-rc.4",

index.d.ts

declare module 'moment' {
    var moment: moment.MomentStatic;
    export = moment;
}

I do have symbolic links in the root of the meteor project:

UPDATE

I have found the problem I think, but I am not 100% sure how to solve it yet.

The issue is that the symbolic links are pointing to directories that exist locally, but not on the remote server.

UPDATE

I remove all symbolic links, and have the files there instead, deploy, and I still get the same error when the server tries to start:

Any Ideas please?

I have run: meteor npm install --save

I have found this in boot.js, but I am not sure what the author was doing.

    try {
      return require(name);
    } catch (e) {
      // Try to guess the package name so we can print a nice
      // error message
      // fileInfo.path is a standard path, use files.pathSep
      var filePathParts = fileInfo.path.split(files.pathSep);
      var packageName = filePathParts[1].replace(/\.js$/, '');

      // XXX better message
      throw new Error(
        "Can't find npm module '" + name +
          "'. Did you forget to call 'Npm.depends' in package.js " +
          "within the '" + packageName + "' package?");
      }

UPDATE

I removed the .gitignore of node_modules/, and I don't get any errors now.

However, I am new to Meteor, so not sure how to test this. But when I try invoke the app with http://remote-thewhozoo.herokuapp.com/ or https://remote-thewhozoo.herokuapp.com/ I get a 404 error:

2016-09-11T16:20:15.183895+00:00 heroku[router]: at=info method=GET path="/sockjs/info?cb=jwgw2yuvgl" host=remote-thewhozoo.herokuapp.com request_id=a49fafb2-9708-46d2-8117-2c789bfa6a3e fwd="105.186.215.147" dyno=web.1 connect=1ms service=2ms status=404 bytes=132

I do check the Mongo Database, and it has got the collections created by my app. So Meteor must be running, I just don't know how to access it.

Any ideas please?

Make sure this line:"moment": "^2.14.1" is your package.json then run npm install
