Question

运行npm run dev时，收到以下错误消息：

Error: Cannot find module 'webpack/bin/config-yargs'

Exit status 1 npm ERR! npm ERR! Failed at the coursetro-eth@1.0.0 dev script. npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

我的环境如下：

OS: Windows 10
NPM: Version 5.6.0
WebPack: Version 4.6

我的package.json文件：

{
   "name":"coursetro-eth",
   "version":"1.0.0",
   "main":"index.js",
   "scripts":{
      "dev":"webpack-dev-server --config build/webpack.dev.conf.js",
      "publish":"ngc -p tsconfig-aot.json",
      "test":"echo \"Error: no test specified\" && exit 1"
   },
   "author":"",
   "license":"ISC",
   "description":"",
   "dependencies":{
      "web3":"github:ethereum/web3.js"
   },
   "devDependencies":{
      "lite-server":"^2.3.0",
      "webpack":"^4.6.0",
      "webpack-cli":"^2.0.15",
      "webpack-dev-server":"^2.11.2",
      "webpack-validator":"^2.3.0"
   }
}

这个错误是什么？

Node.js / npm：在开发模式下运行时找不到模块
