Strange version problems with npm and karma

Question

package.json

I have the following package.json

...
"devDependencies": {
    "karma-coverage": "~0.1.3",
    "karma-chrome-launcher": "~0.1.1",
    "karma-firefox-launcher": "~0.1.2",
    "karma-html-reporter": "~0.1.1",
    "karma-jasmine": "~0.1.3",
    "karma-phantomjs-launcher": "~0.1.1",
    "karma-safari-launcher": "~0.1.1",
    "karma-script-launcher": "~0.1.0",
    "grunt-contrib-jshint": "~0.1.1",
    "grunt-contrib-concat": "~0.1.2",
    "grunt-contrib-uglify": "~0.1.1",
    "grunt-contrib-watch": "~0.5.3",
    "grunt-contrib-clean": "~0.4.0",
    "grunt-contrib-connect": "~0.5.0",
    "grunt-karma": "~0.6.2",
    "grunt-concurrent": "~0.4.2",
    "time-grunt": "~0.1.1",
    "load-grunt-tasks": "~0.2.0",
    "jshint-stylish": "~0.1.3"
},
"peerDependencies": {
    "karma": ">=0.10",
    "grunt": ">=0.4"
},
...

> karma --version

When I call karma --version on the console, I get the following output:

> karma --version
Karma version: 0.12.16

> npm install

When I afterwards call npm install I get the following error:

> npm install

The problem

Why npm doesn't like my karma? :)

Answer 1

Your peerDependancies appears to be wrong, you should be specifying the name of the package, and then the versionied packages it needs,

"name": "karma-coverage",
  "peerDependencies": {
    "karma": "0.9"
  }
}

See the Documentation from npm

although it looks like none of your packages need a particular version of karma, so you could just try adding "karma": "10.0" at the start of your dev dependancies
