npm install fails on Mac OS X El Capitan

[kc14]

After installing:

• jekyll 2.5.3
• node v4.2.1
• Sass 3.4.19 (Selective Steve)
• grunt v0.4.5 with grunt-cli v0.1.13

on my mac, using the standard ruby installation

ruby 2.0.0p645 (2015-04-13 revision 50299) [universal.x86_64-darwin15]

that comes with the OS, npm install fails with:

npm ERR! Failed at the [email protected] install script 'node build.js'.

The problem are the dependencies in package.json. The dependencies:

• "grunt-contrib-sass": "^0.8.1"
• "grunt-sass": "^0.14.2"

are a way to to old for grunt v0.4.5. I changed them to:

• "grunt-contrib-sass": "^0.9.2"
• "grunt-sass": "^1.1.0"

and got at least npm install to work. I have to look further into using this jekyll theme ... as the grunt targets do not seem to work ...

Here is my version of package.json:

{
  "name": "twister",
  "version": "0.1.0",
  "devDependencies": {
    "grunt": "^0.4.5",
    "grunt-autoprefixer": "^1.0.1",
    "grunt-build-control": "^0.3.0",
    "grunt-contrib-copy": "^0.8.0",
    "grunt-contrib-imagemin": "^0.9.4",
    "grunt-contrib-jshint": "~0.10.0",
    "grunt-contrib-nodeunit": "~0.4.1",
    "grunt-contrib-sass": "^0.9.2",
    "grunt-contrib-uglify": "^0.6.0",
    "grunt-contrib-watch": "^0.6.1",
    "grunt-newer": "^1.1.0",
    "grunt-open": "^0.2.3",
    "grunt-responsive-images": "^0.1.6",
    "grunt-sass": "^1.1.0",
    "grunt-shell": "^1.1.1"
  }
}

+1, getting the same error

There is a missing dependency. Add

"load-grunt-tasks":` "^3.5.2"

and the grunt targets will be able to run.
