EJS module not found on OpenShift NodeJS template

I am unable to use EJS as my view render engine on NodeJS.

I have found several similar questions but all state about installing EJS that really work for others. This is not same for me, may be because I am unable to choose the right directory (among so many duplicates in OpenShift repo) for the installation.

I have NodeJS default app created by OpenShift template. While installing EJS dependency I somehow screwed it and I get following error (standard NodeJS error for unavailable module):

Error: Cannot find module 'ejs'
    at Function._resolveFilename (module.js:337:11)
    at Function._load (module.js:279:25)
    at Module.require (module.js:359:17)
    at require (module.js:375:17)
    at View.templateEngine (/usr/lib/node_modules/express/lib/view/view.js:134:38)
    at Function.compile (/usr/lib/node_modules/express/lib/view.js:68:17)
    at ServerResponse._render (/usr/lib/node_modules/express/lib/view.js:417:18)
    at ServerResponse.render (/usr/lib/node_modules/express/lib/view.js:318:17)
    at /var/lib/openshift/5123c2494382ec16ca000222/app-root/runtime/repo/server.js:114:17
    at callbacks (/usr/lib/node_modules/express/lib/router/index.js:272:11)

Besides mentioning in package.json, I tried installing ejs through terminal at app-root, runtime and nodejs-0.6 level as well (and restarting of the app), but of no use.

My directory structure is:

-app-root
---data
---repo
-----node_modules (has ejs)
-----server.js
-----package.json ("dependencies": {"ejs" : ">=0.8.3"},)
-----views
-------defaultError.ejs
---runtime
-----data
-----node_modules (empty)
-----repo (identical to app-root/repo)
-------node_modules (has ejs)
-nodejs-0.6
---data
---repo (identical to app-root/repo)
-----node_modules (has ejs)
---runtime
-----node_modules (empty)
-----repo (identical)
-------node_modules (has ejs)

defaultError.ejs is just plain html. server.js has following:

self.createRoutes = function() {
        self.routes = { };

        //...
        self.routes['/'] = function(req, res) {
            res.setHeader('Content-Type', 'text/html');
            res.send(self.cache_get('index.html') );
        };

        self.routes['/helloejs'] = function(req, res){
            res.render('defaultError', { layout:false } );
        };
    };

self.initializeServer = function() {
        self.createRoutes();
        self.app = express.createServer();

        self.app.set('view engine', 'ejs');
        //  Add handlers for the app (from the routes).
        for (var r in self.routes) {
            self.app.get(r, self.routes[r]);
        }
    };

Hope this long post makes my problem clear :)

when install ejs you must use option --save:

npm install ejs --save

and create .gitignore file:

node_modules

I my case, I just added ejs manually in package.json:

 {
   "name": "myApp"
   "dependencies": {
     "express": "^4.12.2",
     "ejs": "^1.0.0"
   }
 }

And run npm install (may be you need run it with sudo) Please note, that ejs looks views directory by default

The error is due to using incorrect directory. You have to install packages and run your application from your project directory. Here is the directory structure of the folder i use as a project.

.
├── app.js
├── node_modules
│   ├── express
│   ├── jade
│   └── socket.io
├── package.json
├── public
│   ├── images
│   ├── javascripts
│   └── stylesheets
├── routes
│   ├── index.js
├── server.js
└── views
    └── layout.jade

Using npm install from this folder adds package folder within the node_modules sub folder (like express, socket.io). You should use node from this location, as all locally installed modules are visible from this folder only.
