karma start Cannot find module 'jasmine-core'

Question

I was getting the following error when I ran \"karma start\"

module.js:340 throw err; ^ Error: Cannot find module \'jasmine-core\' at

Answer 1

Even with karma and karma-jasmine installed in the local project's node_modules you must still npm install jasmine.

So for a fresh Karma project:

1. npm install karma karma-jasmine jasmine to install the required modules locally.

Optionally add --save-dev to write to your package.json. Note these do not need to be -g globally installed here.

2. karma start

This step requires you to have Karma installed globally (sudo npm install -g karma).
