Hi, When I updated from angular-cli to @angular/cli, i also faced the same issue: Error: Cannot find module 'angular-cli/plugins/karma'

The solution worked for me is to update the karma.conf.js file present in root folder of the project.

frameworks: ['jasmine', '@angular/cli'],
...
plugins: [
      require('karma-jasmine'),
      require('karma-chrome-launcher'),
      require('karma-remap-istanbul'),
      require('@angular/cli/plugins/karma')
    ],
...
preprocessors: {
      './src/test.ts': ['@angular/cli']
    },
...

After this change, ng test should work.

Check if angular-cli/plugins/karma exists in the node_modules directory.

In my case the problem was that I had migrated to @angular/cli package, but karma.conf.js was still referencing the angular-cli paths. I updated my references by comparing to the karma.conf.js from this repo: https://github.com/angular/angular-cli/blob/master/packages/%40angular/cli/blueprints/ng2/files/karma.conf.js
