模块webpack-dev-server的问题：找不到模块'webpack-cli / bin / config-yargs'

Question

我正在尝试使用webpack-dev-server，但是当我执行命令 yarn（commandName） 时，它返回一条错误消息：< strong>找不到模块“ webpack-cli / bin / config-yargs” 。我已经在Yarn中添加了模块，但是仍然无法执行。

我的package.json：

  "version": "1.0.0",
  "main": "index.js",
  "license": "MIT",

  },
  "scripts": {
