socket.io + node.js on heroku

Question

I\'m having some issues in compiling a socket.io app on heroku.

Thats the app.js file

var app = require(\'express\').createServer()
   , io = require         


        

Answer 1

Heroku is failing to build hiredis. The reason is that hiredis (the node.js module) depends on hiredis (the C library), which needs GNU make, which is not available on your slug.

Question is, why is NPM trying to build hiredis while it's not in your dependencies ?

You should check if hiredis appears anywhere in your project (grep -R hiredis .). Another possibility is that Heroku is trying to provide redis to all node.js apps ?

I'd check with Heroku's support.
