Failed to rebuild dependencies with npm

Question

As I am trying to push my nodejs app which is working fine locally to heroku, here is what I get in terminal:

dcaclab@ubuntu:~/RubymineProjects/nodejs_consumer$ git push heroku master

here is my package.json file:

  }
}

Any idea please?

EDIT

Tried to use node 0.8, here is what I got:

Answer 1

So the rbytes package has been unchanged for 2 years, and in that time node has switched from the node-waf build system to node-gyp. As of node v0.10.0, node-waf is no longer included thus the sh: node-waf: not found error message. I think you have a few options (in order of preference):

1. Use a more modern module instead of rbytes
2. Convince the author of rbytes to update to support recent node and release a new version
3. Fork rbytes and fix it yourself
4. Set your package.json engine to node 0.8 and try again

EDIT

Well, error message #2 still looks like rbytes doesn't build properly. I'd have to dig into that package particularly to understand the error. Not sure how/why it's working for you locally but having problems on heroku, but I think it's time for the rbytes maintainer to do some maintenance.

Answer 2

I had this issue after a fresh compile of the latest version of node.js in Ubuntu. As per Peter Lyon's advice, the issue has to do with node-gyp not being around. Usually, when installing from a pre-compiled package this is not a problem (aptitude and the rhel repos usually include node-gyp by default).

However, if you are building from source, it's likely node-gyp isn't there, which is what caused the issue in my case.

This solved it for me:

sudo npm install -g node-gyp

After that, running npm install worked fine, the errors vanished!

Answer 3

Stay away from rbytes, and in general from any un-maintained module, especially one doing something important and subtle like crypto. You can get everything you need from using Node's native crypto module. See http://nodejs.org/api/crypto.html#crypto_crypto_randombytes_size_callback :

crypto.pseudoRandomBytes(256)

Answer 4

I faced same issue, just remove existing node_module directory. and then run npm install. That's it
