If you have the same error

Downgrade to 2.9.7 temporarily.

npm install --save-dev webpack-dev-server@2.9.7

[emodo]

+1

[ganesharulanantham]

Same issue, Never realised it is related the version upgrade

[emodo]

@ganesharulanantham Me too, it took me lots of time to figure out

[avaleriani]

Same error here, was working before update.

[l0gicgate]

Same issue. Config has not changed. Please fix

[sricc]

Same. v2.9.7 is working fine for me.

[AjiMIde]

Same error here, was working before update. Use vue-cli to build a new project but......

[jpamorgan]

Same here! Still haven't been able to resolve the issue

[JackSoby]

having the same issue

[subramn]

Same issue for me as well

[vanessapr]

Same error!, I am using v2.9.7 instead v2.10.

[kylecombes]

This is an issue on Ubuntu 16.04 as well.

[brettstack]

"Same here" comments are not helpful. Please just +1 the issue. If you want to be notified of updates, click the "Subscribe" button to the right.

[ArtOfCode-]

Hit this issue too. Moving back to 2.4.5 is a temporary fix; all higher versions that I've tried have been affected.

[ghost]

Is anyone here using yarn? Found a good ol' removal of node_modules and an npm install did the trick

[ArtOfCode-]

@readeujet I am; tried that with no dice.

[l0gicgate]

@readeujet that doesn't work for me either.
@ArtOfCode- Rolling back to 2.9.7 works at the moment.

[strausd]

Same issue running yarn on Windows 10. Tried deleting node_modules and running yarn install as mentioned previously, but that did not work. Downgrading to 2.9.7 worked for me.

[chetanraj]

installing node modules from yarn is the issue, did npm i it worked.

[FourwingsY]

in my case, installing from yarn worked, but from npm throws error.

[jinyun]

Both yarn and npm can not worked for me , downgrading to 2.9.7
node:v8.9.3
os: ubuntu1604

[orangeyyy]

I have got the same issue ++1

[sidlynx]

I got the same problem.I'm using version 2.9.2.node version 8.9.4 on ubuntu 16.tried both npm and yarn I still have the same issue

[Tankpt]

I have got the same issue

[jovanNajdic]

Same problem. I'm using v2.9.1, node v9.3.0, windows 10. Tried both npm and yarn.

worked:
npm install webpack-dev-server@2.9.7 --save-dev
and inline:false

[DanielQuero]

Edit: @guohui8 Solution worked for me (npm install webpack-dev-server@2.9.7 --save-dev). At least until they fixed it.

How did you roll back to that version?

PS: Same Issue on Arch-Linux

[chabanov]

Someone found a solution to the problem?

[guohui8]

I have solved this problem by this command:
npm install webpack-dev-server@2.9.7 --save-dev

[davidpelayo]

Same here. The changes done on this new version are the following: v2.9.7...v2.10.0

[sebtoun]

specifically commit 00e8500 introduce the bug and even more specifically changing yargs dep from 6.6.0 to 10.0.3

[shellscape]

To everyone on this issue who replied "me too" - this is not said to be rude, and I say this with ❤️ -
github reactions have been around for nearly two years now (https://github.com/blog/2119-add-reactions-to-pull-requests-issues-and-comments) specifically to combat the "me too," "same issue" replies. Adding those replies to an issue does nothing but make it harder for maintainers to read legitimate information added to the issue by other users. In short, you're hurting the issue more than helping. You should know better by now.

We've locked this issue to prevent further flooding in of those kinds of comments. That said, we're working on resolving the problem today.

[shellscape]

yargs has been rolled back to v6.6.0 in webpack-dev-server@2.10.1. Issue is resolved. We'll look into the breakages of that dependency update and issue a patch once an upgrade path is found.

[shellscape]

Also just added a test to make sure that this dependency doesn't get updated again. It's bit us a few times in the past. Tests will now fail (preventing publish) if that is updated again. Perhaps at some point in the future we'll move away from yargs to something more minimal.

[csvan]

Confirming that this is a yargs issue. For us it happened when moving from "~10.0.3" to "~10.1.1" on webpack 3.10.

@coolapollo you're necro-bumping on a closed issue with many participants. It happens. It's fine, but try not to do it 😉 .
See this description of necro bumping if you'd like a more detailed explanation. It has suggestions on what to do instead too 👌 .

First of all, you have installed webpack, webpack-cli and webpack-dev-server the wrong way. You made them dependencies and not devDependencies. To change that, uninstall them:

npm uninstall webpack webpack-cli webpack-dev-server

and then install them properly:

npm install webpack webpack-cli webpack-dev-server --save-dev

And I found a solution that adding a new script or in your Start Script in package.json worked for me. So you can try this way as well.

"scripts": { 
"dev": "webpack serve --mode development --env development"
}

And add this snippet in your webpack.config.js file [ contentBase is directory of your index.html file ].

module.exports = {
   devServer : {
          contentBase : __dirname + '/public',
          inline : false,
      },
 }

Finally run this on your terminal

npm run dev
