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

enter image description here

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",

index.d.ts

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

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

enter image description here

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.

enter image description here

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.

enter image description here

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

enter image description here

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?

My localhost is a Windows machine, and heroku is Linux. Is it maybe due to a case sensitivity issue or something?Manas

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

Donatelli answered 9/9, 2016 at 14:19 Comment(4)
I just added the package.json to the question above. It does have "moment": "^2.14.1"Manas
If issue is still presisting, I would do both npm install -g moment and npm install moment where the later is obviously in your meteor root directory.Donatelli
I do try meteor npm install --save moment & npm install -g moment & npm install moment, but then when I try do a git add/commit/push it says no changes made. Your branch is up-to-date with 'origin/master' Any ideas please?Manas
That should not be a problem. Usually changes in node_modules are not detected because they should get installed automatically from package.jsonDonatelli

Can you try meteor npm install in your project root?

If moment didn't appear in that list, can you try meteor npm install --save moment?

Otherwise, could you please post your package.js - it should be in app/programs/server/

Thanks, I am busy trying that now. I am just doing the git push. A quick question, is it correct to have a gitignore of node_modules?Manas
That's fine, just remember to npm install every time you clone it to a new machine or pull after changing any dependencies.Admittance

I think it's a problem with your buildpack. Try following this guide - https://meteorcoder.wordpress.com/2016/09/24/how-to-deploy-meteor-apps-with-heroku/

I ran: npm install moment react-moment & it worked. The official npm site has two different ways of installing this & they both gave me errors.

To solve the error "Cannot find module 'moment'", make sure to install the moment package by opening your terminal in your project's root directory and running the following command: npm i moment and restart your IDE and development server.
