I'm using Node Boilerplate and it all worked fine until I decided create another project on top of it(in another dir).

Now I have exactly the same code base(this project AS IS) in two different folders. I can run one of it without any problems but another one is failing with:

% node app.js
node.js:116
        throw e; // process.nextTick error, or 'error' event on first tick
        ^
Error: Cannot find module 'connect/middleware/router'
    at Function._resolveFilename (module.js:299:11)
    at Function._load (module.js:245:25)
    at require (module.js:327:19)
    at Object.<anonymous> (/home/gotts/Sites/nodejs-uploadr/lib/express/lib/express/server.js:17:14)
    at Module._compile (module.js:383:26)
    at Object..js (module.js:389:10)
    at Module.load (module.js:315:31)
    at Function._load (module.js:276:12)
    at require (module.js:327:19)
    at Object.<anonymous> (/home/gotts/Sites/nodejs-uploadr/lib/express/lib/express/index.js:28:31)

There is similar problem explained here - https://github.com/visionmedia/express/issues/535 which says that the problem is in the incompatible version of connect/express.

But how is this possible? Source code is exactly the same in two folders and it work fine in one copy and fails in another?

Do the two folders share a common parent? Node looks for modules in ~/.node_modules and /node_modules in your app dir.
