If you have the same error

[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]

[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

[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 [email protected] --save-dev
and inline:false

[DanielQuero]

Edit: @guohui8 Solution worked for me (npm install [email protected] --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 [email protected] --save-dev

[sebtoun]

same here, commit 00e8500b0853312be3cf369976509fbce2a4b7dc seems to have introduced this bug.

[GoKu-gaga]

npm install [email protected] --save-dev

[chabanov]

rollback version is prohibited by the company's protocol

[ricosmall]

I solved this problem by reinstall version 2.9.7 of webpack-dev-server:
yarn add -D [email protected]

[larister]

Could this be a repeat of https://github.com/webpack/webpack-dev-server/issues/1087?

[yongjie-xu]

I have got the same issue ++1

[sebtoun]

for those who have to work with old browsers incompatibles with es6, downgrade to 2.7.1 to have livereload working:
npm install --save-dev [email protected]

[Suixinlei]

same issue, version 2.9.7 will help.

[ajhsu]

Got the same issue here, and it breaks the latest version of vue-cli

[dangger]

Mac OS:10.12.6

rollback webpack-dev-server version to 2.9.7 fix it.

npm install [email protected] --save-dev

[dolgiyspb]

I have got the same issue
If i copy webpack-dev-server which installed 2 days ago it works fine (just cp -r /old_project/node_modules/webpack-dev-server/ /new_project/node_modules/).
rollback version to old versions (2.9.7, 2.9.3) does not fork for me.

[larister]

Public Service Announcement: Please do not comment with +1, Same here, etc. Instead, click the "thumbs up" icon underneath the opening post:

[sidlynx]

As stated before.The problem is the new version of webpack-dev-server.A simple downgrade does the trick.
Try
npm install --save-dev [email protected] and try again

[sebtoun]

Downgrading yargs dependency in webpack-dev-server from 10.0.3 to 8.0.2 fixes this issue. So it really looks like it is a yargs problem.

[Sun1ive]

faced same issues here, downgrading manually to 2.9.7 helped

[davidpelayo]

Same here. The changes done on this new version are the following: https://github.com/webpack/webpack-dev-server/compare/v2.9.7...v2.10.0

[sebtoun]

specifically commit 00e8500b0853312be3cf369976509fbce2a4b7dc 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 [email protected]. 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.
