Webpack开发服务器配置- contentBase在最新版本中不工作

Question

当我将webpack升级到4.0.0-beta.3并运行npx webpack serve时，我得到了这个错误：

[webpack-cli] Invalid configuration object. Object has been initialized using a configuration object that does not match the API schema.
 - configuration has an unknown property 'contentBase'. These properties are valid:
   object { bonjour?, client?, compress?, devMiddleware?, firewall?, headers?, historyApiFallback?, host?, hot?, http2?, https?, liveReload?, onAfterSetupMiddleware?, onBeforeSetupMiddleware?, onListening?, open?, port?, proxy?, public?, setupExitSignals?, static?, transportMode?, watchFiles? }

这是我在3.11.2中工作的webpack.config.js：

const path = require('path');
const ArcGISPlugin = require("@arcgis/webpack-plugin");

module.exports = {
  mode: 'development',
  entry: {
      main: './app/main.js'
  },
  plugins: [
      new ArcGISPlugin()
  ],
  devServer: {
      contentBase: './'
  }
}

我来自package.json的devDependencies：

  "devDependencies": {
    "@arcgis/webpack-plugin": "^4.18.0",
    "dojo-typings": "^1.11.11",
    "webpack-cli": "^4.7.2",
    "webpack-dev-server": "^4.0.0-beta.3"

我需要如何更新我的配置以获得最新版本的工作？当我取出dev服务器对象时，服务器将运行，但提供的内容来自./public，而./public并不存在。

我是新手，所以对应用程序、配置和需求还不熟悉。

Answer 1

  devServer: {
  static: './'
 }

我应该更仔细地阅读错误。上面的对象使我的配置再次工作。
