Answer 1

Try changing webpack version to 3.0 and web-dev-server to 2.7.1

Eg:

"devDependencies": {
    "webpack": "^3.0.0",
    "webpack-cli": "2.0.13",
    "webpack-config-utils": "2.0.0",
    "webpack-dev-server": "^2.7.1",
    "webpack-validator": "2.2.7"
}

Answer 2

Update your Webpack version (and webpack CLI):

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

If you don't use one of those mentioned above, feel free to omit.

Answer 3

these worked for me:

"webpack": "^4.31.0",
"html-webpack-plugin": "^3.0.0",
"webpack-bundle-analyzer": "^3.3.2",
"webpack-cli": "^3.3.2",
"webpack-dev-server": "^3.3.1",
"webpack-merge": "^4.1.0"

Answer 4

I forgot to install webpack-cli. So I ran below command and issue got fixed.

npm i -D webpack-cli

Answer 5

I have used these dependencies Working for me.

"webpack": "^3.0.0",
"webpack-cli": "2.0.13",
"webpack-config-utils": "2.0.0",
"webpack-dev-server": "^2.7.1",
"webpack-validator": "2.2.7"

Answer 6

The general situation is due to Webpack and webpack-dev-server version is not compatible. Like I also have this problem, my computer's webpack is 1.15.0, but webpack-dev-server is 2.x above version. So I uninstall webpack-dev-server: npm uninstall webpack-dev-server -g Then install the 1.15.0 version of webpack-dev-server, you can solve this problem by npm install webpack-dev-server@1.15.0 -g
