If it's a config issue, it should be mentioned somewhere.

The same with vue-loader@14 yields

}

And I have no idea what path is required

Can't reproduce.
I noticed that you didn't install webpack-cli in your project locally. Maybe that's the problem. You might have been using an outdated version of webpack-cli

@tarkhil What @vue/cli version do you use?

vue --version

I guess using an outdated version, upgrade to Vue CLI v4.5.10 and it should work.

[tarkhil]

Yes, thanks. Sorry for false report

I am having the same issue, and I'd wish to use vue-loader without vue-cli. Isn't this possible? Relevant parts of package.json:
"scripts": { "dev": "webpack-dev-server", "build": "webpack --mode production" }, "dependencies": { "vue": "3.0.7" }, "devDependencies": { "vue-loader": "16.1.2", "vue-template-compiler": "2.6.12", "webpack": "5.28.0", "webpack-cli": "4.5.0" }

I tried using both stable (15.9.6) and next version of vue-loader.

@samipe

• Vue 3 requires vue-loader v16 + @vue/compiler-sfc;
• Vue 2 requires vue-loader v15 + vue-template-compiler.

I think this might be related: webpack/webpack#12606

[FlyDreame]

I think I have found a solution to the problem. The main reason for this problem is the webpack imported by vue-loader and the webpack imported by @vue/cli-service are not the same module.

In other words，@vue/cli-service import the webpack in node_modules/@vue/cli-service/node_modules/webpack，vue-loader import the webpack in node_modules/webpack.

So the key to solve the problem is to unify the webpack version。You can try the following ways until there is no webpack module in node_modules/@vue/cli-service/node_modules/webpack.

clear node_modules, delete package-lock.json, and then npm i

If the ways do not work, you have to check the version of webpack in node modules/@vue/cli-service/node_modules/webpack. For example, if the version of webpack is 5.22.0, then npm i webpack@5.22.0 -D and repeat the ways .
