Possible missing dependency on babel-runtime

[christopherthielen]

I'm submitting a bug report

Webpack version: 3.11.0

Webpack Karma version: 1.7.x

Karma version: 2.0.11

Please tell us about your environment: OSX

Current behavior:

$ karma start
25 02 2018 19:56:08.367:ERROR [config]: Error in config file!

• If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem along with a gist/jsbin of your webpack configuration.

git clone https://github.com/ui-router/sticky-states.git
cd sticky-states
git checkout karma-webpack
yarn
yarn add --dev karma-webpack@2.0.11
yarn test

Adding babel-runtime as a dep fixes the issue. Guessing this was due to https://github.com/webpack-contrib/karma-webpack/commit/6d28c5cf1246e1659a7553c18af6f43de84a7db5. 2.0.9 was the last version of karma-webpack that worked without babel-runtime.

We had to lock version to 2.0.9 as this breaking change was not announced properly

Could someone please quick review (#310) ?

Released in v2.0.12 🎉

  Perhaps you are missing some plugin?

😞 Could include some context ({Error} Logs,package.json etc), did you clean the npm/yarn cache and updated the lockfile etc ?

[CaseyPeters]

@michael-ciniawsky updated my previous comment with out console output. We are using it as a dev-dependency so it will not be included in our lockfile. I did clear the npm cache

On project with webpack@3.7.1 karma@1.7.1 karma-webpack@2.0.12 the following error is encountered.

ERROR [plugin]: Error during loading "C:\project\node_modules/karma-webpack" plugin:
  Cannot find module 'babel-runtime/helpers/toConsumableArray'
ERROR [preprocess]: Can not load "webpack", it is not registered!

This seems to be caused by the fact project doesn't use babel and babel-runtime is not provided as dependency by karma-webpack. Thus require call fails on _\nodemodules\karma-webpack\lib\karma-webpack.js:3

var _toConsumableArray2 = require('babel-runtime/helpers/toConsumableArray');

Not sure why there is no notice, but just FYI: this was fixed in #312. Note: could well be that it's gonna be reverted 😃
