Node.js - cannot find module


Question

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?

Accepted Answer

OK, let me answer my own question:

Sorry for misinformation - those two folders were not exactly the same(I'm gonna need to learn unix diff better). And there it require("connect") in code

Local checkout of connect into /lib folder takes precedence but if it's not there - connect will be loaded from the ~/.node_modules as Ricardo previously set.

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