问题:

Getting error when running webpack-dev-server --config config/webpack.dev.js --progress --profile --watch --content-base src/. Here is the error log:

module.js:442 throw err; ^  Error: Cannot find module 'webpack/bin/config-yargs' at Function.Module._resolveFilename (module.js:440:15) at Function.Module._load (module.js:388:25) at Module.require (module.js:468:17) at require (internal/module.js:20:19) at Module._compile (module.js:541:32) at Object.Module._extensions..js (module.js:550:10) at Module.load (module.js:458:32) at tryModuleLoad (module.js:417:12) at Function.Module._load (module.js:409:3)

I've had a similar problem. I think it's related to webpack version. After changing webpack version the latest everything was fine...

回答2:

Try changing the webpack version from 1.x to 2.x in your package.json:

Eg:

 "devDependencies": {     "webpack": "2.2.0-rc.3",     "webpack-dev-server": "2.1.0-beta.0",     "webpack-validator": "^2.3.0"   } 

This happens sometimes when you use pre-release version of webpack-dev-server with released version of webpack or viceversa.

I also go this error when I had only installed webpack locally and hadn't installed it globally yet.

I had webpack-dev-server installed globally though and it had a dependency on a global install of webpack. To be fair npm did complain while installing webpack-dev-server:

UNMET PEER DEPENDENCY webpack@^2.2.0

I fixed this solution by running npm start which was just a wrapper running 'webpack-dev-server' rather than running webpack-dev-server directly into the console. The problem was that I was passing options into a method I should not have been passing options into.

Running webpack-dev-server with npm start showed me the correct error message. Running webpack-dev-server directly only gave me "Error: Cannot find module 'webpack/bin/config-yargs' ". Weird.

I am on: "webpack": "^2.6.1", "webpack-dev-server": "^2.7.1"

回答5:

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

This is usually due to version mismatches between libraries (including webpack/yargs, in your case). This can happen a lot when you have left a project sitting for a while and some dependencies in your node_modules directory have become stale. A very simple solution, before fussing with different versions of everything, is to just move your node_modules directory to a temporary location and re-run npm install:

% mv node_modules nod_modules.REMOVED % npm install 

Then, try rerunning webpack.

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" }
