Cannot find module 'socket.io/node_modules/redis'

Question

Cannot find module 'socket.io/node_modules/redis'

When trying to do

var redis = require('socket.io/node_modules/redis');

I get the error "Cannot find module 'socket.io/node_modules/redis" and I can't figure out why. I am running windows and ran "npm install socket.io"

It seems like the same issue here: Error: Cannot find module 'socket.io/node_modules/redis' but the redis server is up and running.

In my "socket.io/node_modules" folder I don't see anything Redis related.

node.js
redis
socket.io

Answer 1

The socket.io package.json doesn't show a dependency on redis:

  "dependencies": {
    "engine.io": "Automattic/engine.io#15afd3",
    "socket.io-parser": "2.2.1",
    "socket.io-client": "Automattic/socket.io-client#05c9632",
    "socket.io-adapter": "0.2.0",
    "has-binary-data": "0.1.3",
    "debug": "0.7.4"
  }

Either way, theres no need to directly depend on another library's dependencies. If you need to use redis in your code, you can install redis and add it to your package.json using:

npm install redis --save

and require like:

var redis = require('redis');

Answer 2

It seems that you're using Socket.IO 1.0. Since 1.0 there is no more redis dependency. You can follow @go-oleg's recommendation and install redis package on your own.
