Unable to run npm install successfully due to unmet peer dependencies

Question

I have package.json file in which following devDependencies are mentioned:

"devDependencies": {
    "bower": "^1.7.7",
    "connect-ssi": "^1.1.0",
    "grunt": "~0.4.5",
    "grunt-contrib-compass": "^1.1.0",
    "grunt-contrib-concat": "~0.4.0",
    "grunt-contrib-connect": "^0.11.2",
    "grunt-contrib-handlebars": "^0.11.0",
    "grunt-contrib-jshint": "~0.10.0",
    "grunt-contrib-qunit": "~0.5.2",
    "grunt-contrib-sass": "^0.9.2",
    "grunt-contrib-uglify": "~0.5.0",
    "grunt-contrib-watch": "~0.6.1",
    "grunt-jsdoc": "^1.1.0",
    "karma": "^0.13.22",
    "karma-jasmine": "^0.3.7"
  }

Now when I run npm install it gives me following errors:

UNMET PEER DEPENDENCY jasmine-core@* npm WARN EPEERINVALID karma-jasmine@0.3.8 requires a peer of jasmine-core@* but none was installed. npm WARN EPACKAGEJSON hirebuddy-prototype@0.0.1 No repository field.

hirebuddy-prototype is the name in the package.json.

Will running npm install install all the dependencies mentioned in the package.json or do I need to install jasmine-core and karma-jasmine separately?

Answer 1

This is a weakness in karma-jasmine. In its package.json, jasmine-core is listed as a peerDependency, and NPM 3 no longer installs these automatically. So you have to add jasmine-core in your own package.json. So just npm install jasmine-core --save-dev , and cross your fingers that the latest version is compatible. It should be.
