here is my package.json file

  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },

I change karma version to ~0.12.37 and karma-webpack to ~1.6.0，it works;
But when karma-webpack is 1.7.0, it throw errors when I run karma start karma.config.js

The text was updated successfully, but these errors were encountered:

Duplicate of #68 and see #63 for more details. You need to upgrade karma to 0.13 to fix the issue

pojka · 2015-08-04T12:42:22Z

I'm seeing this issue with fixed versions of karma 0.13.4 and karma-webpack 1.7.0

@pojka could you show me the output of npm ls please

pojka · 2015-08-04T13:09:10Z

@dignifiedquire sure - https://gist.github.com/pojka/49307fbb77d1c0ee18ed

Please let me know if I'm being dumb :)

dignifiedquire · 2015-08-04T13:18:06Z

@pojka looks like there is another bug in there :( thanks for the report

kmaraz · 2015-08-11T11:03:56Z

I have the same problem, how can I temporarily solve this? Or I need to wait for fix? Thanks.

EDIT: Or can I help you with my logs?

pojka · 2015-08-11T11:05:58Z

@kmaraz using the following combination works for me for the moment:

"karma": "0.12.37", "karma-webpack": "1.6.0",

kmaraz · 2015-08-11T11:07:38Z

@pojka Thanks!
@dignifiedquire If you need my logs, just tell me, please.

andrevinsky · 2015-08-12T00:20:18Z

Hello, isn't there a way NOT to use old versions? 👍

leoselig · 2015-08-13T10:24:50Z

+1
we are experiencing the same issue

dignifiedquire · 2015-08-13T10:28:29Z

Does someone have repo which fails with this error, using karma@0.13.9 and karma-webpack@1.7.0 that I could look at?

…k#70

ebordeau · 2015-08-18T19:08:04Z

I updated to karma@0.13.9 and karma-webpack@1.7.0 and it worked for me. Thanks!

pojka · 2015-08-19T02:47:32Z

@dignifiedquire not working for me with karma@0.13.9 and karma-webpack@1.7.0 either

I've stripped everything down to a very basic config and a hello world test, repo is here - https://github.com/pojka/debug-karma-webpack-70

If you change to karma@0.12.37 and karma-webpack@1.6.0 the test runs

thomasklein · 2015-09-01T08:50:02Z

Hi! karma@0.13.9 and karma-webpack@1.7.0 also did not work for me, so I downgraded to karma@0.12.37 and karma-webpack@1.6.0 and it triggers the following error (which I think is new in the current stack of error messages and might therefore have another cause):

thomasklein · 2015-09-01T09:00:35Z

My problem was solved by upgrading to the latest version of webpack.

claudiopro · 2015-09-08T09:24:27Z

Same issue here. I'm running a clone of https://github.com/pheuter/essential-react with

karma@0.12.37
karma-webpack@1.7.0
webpack@1.12.1

Full output of npm ls here

dignifiedquire · 2015-09-08T09:28:25Z

@claudiopro you need to upgrade karma to 0.13

claudiopro · 2015-09-08T09:29:39Z

@dignifiedquire thanks, karma@0.13.9 did solve the issue!

dignifiedquire · 2015-09-08T10:16:00Z

@pojka @jingzhou123 I've just checked you repo and everything is working fine for me, I ran

$ npm install
$ node_modules/.bin/karma start karma.conf.js

Could you check that you are using karma-cli and not karma installed globally, and make sure the global version which you call with karma is actually up to date.

pojka · 2015-10-20T15:34:40Z

@dignifiedquire that was indeed the issue, thank you for your patience!

dignifiedquire · 2015-10-20T15:48:12Z

Closing this as all issues seem to have been resolved.

joeheyming · 2016-06-29T23:07:11Z

wow, this whole time I wasn't using node_modules/.bin/karma and was instead using the global karma.

Just wanted to say this in case anyone else had the same issue.

besh · 2016-07-19T21:38:28Z

@joeheyming Good call out. Didn't even think of that. Completely fixed my issues.

yinsang · 2018-09-18T08:25:45Z

Two ways to use karma start.

if you had done npm install -g karma-cli, you can use karma start directly in commander(not in package.json)
if you use npm scripts like
"scripts": {
"test": "karma start"
},

, try npm install -SD karma-webpack webpack,then usenpm run test
