+1 I am getting the same issue

[LennartRoeder]

same here

[Zunon]

Same here, is there any other thing I need to do besides turning require('express') into require('express.io') ?

[danibram]

Same here, in node 5.
If you check this file on the error line (/node_modules/express.io/lib/index.coffee:4:13), you see:

connect = require 'express/node_modules/connect'

What version of node you have? I have the 5 and this error happen, for example if i use an old version 0.12 and 4 works. I think is an incompatibility with the new npm flat structure in node_modules.
And also if you change the line by:

connect = require 'connect'

Works!But I dont think is the best solution

+1 Also having this issue with Node.js 5. Is express.io still maintained?

[jan-rus]

Is express.io still maintained? It would be great to fix this issue. Thanks!

Here's what I added to solve similar issues

npm install coffee-script -D;
npm install connect -D;

One can read npm-debug.log on the root directory of your project to see the error messages, and solve them one by one. I hope it helps.

npm --save -d install express.io
npm --save -d install coffee-script
npm --save -d install connect

gets it working on npm (v3.9.0) and node (v0.10.42)

package.json turns out to be like this

...
  "dependencies": {
    "coffee-script": "^1.10.0",
    "connect": "^3.4.1",
    "express.io": "^1.1.13"
  }
...

Hope that helps, although it'd be better if express.io updates this in the next release (?)

Unfortunately even after installing connect and coffee-script the server wont run and I still get these Errors of missing required stacks.
