Updated node on my system, now grunt won't run in npm project

Question

I recently updated node on my computer to 0.12.4. And that seems to have done something to a project I’m working inside node.js express.js. As near as I can tell there appears to be come kind of compatibility issue between the version of node I’m now running and the node_modules. I used Git to go back to previous versions of this project (versions which worked fine) and now they don’t work either.

My computer is running: OSX Yosemite 10.10.3 node: 0.12.4 npm: 2.11.3

My project’s dependancies in my package.json file:

    "dependencies": {
      "body-parser": "~1.8.1",
      "cookie-parser": "~1.3.3",
      "debug": "~2.0.0",
      "express": "~4.9.0",
      "grunt": "^0.4.5",
      "grunt-sass": "^0.17.0",
      "jade": "~1.6.0",
      "morgan": "~1.3.0",
      "node-sass": "^1.2.3",
      "serve-favicon": "~2.1.3"
    },
    "devDependencies": {
      "grunt-contrib-watch": "^0.6.1"
    }

The problem: When I run grunt in the terminal I get errors telling me:

    Loading "sass.js" tasks...ERROR
    >> Error: Cannot find module 'node-sass'
    Warning: Task "sass" not found. Use --force to continue.

So I removed all the node_modules and ran npm install in the terminal and I get more errors:

What should I do?

You're using an ancient version of node-sass (^1.2.3, while the current version is 3.2.0), so try installing a more recent version (which installs just fine for me with Node 0.12):

$ npm i node-sass@latest --save
