requires not working on node v5.2.0

[Anthonyzou]

For some reason doing a simple require('zmq') will fail to import. It will lead to a cannot find module error. However a require('./node_modules/zmq') works fine.

[ronkorving]

Sounds more like a problem in your project than in zmq... Mind sharing a bit more about your file structure and package.json information?

[Anthonyzou]

There is literally nothing in the project (it just started) except for zmq and requires only a simple npm install for zmq. The code is doing nothing interesting except trying to require zmq. Switching to node to v4.2.3 has no problem with a require('zqm').

This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sensible defaults.

See `npm help json` for definitive documentation on these fields
and exactly what they do.

Use `npm install <pkg> --save` afterwards to install a package and
save it as a dependency in the package.json file.

[ronkorving]

Are you perhaps forgetting to re-install zmq between Node major versions? You have to rebuild the binary, because Node's internal API is not compatible between major versions.

[Anthonyzou]

That's weird because I built zmq with node v5.2 and it works fine with v4.2. Anyways, there is just something wrong with the 5.2 distribution because it won't load any modules. Thanks though!

[ronkorving]

Good luck

[Anthonyzou]

Oh found out for some reason the node v5.2 REPL will not load modules from the node_modules folder.

[reqshark]

guys.. It's not zeromq. I was having problems with 5.2 require in the node REPL with fedor's ip module. I think it's a node problem

[reqshark]

btw that got fixed in 5.3 nodejs/node#4215
