Vue.config.js 配置报错 ValidationError: Invalid options object.

接手了别人的项目，在配置 devServer 时直接照搬了之前的配置结果报错

 ValidationError: Invalid options object. Dev Server has been initialized using an options object that does not match the API schema.
         - options has an unknown property 'disableHostCheck'. These properties are valid:
           object { allowedHosts?, bonjour?, client?, ***press?, devMiddleware?, headers?, historyApiFallback?, host?, hot?, http2?, https?, ipc?, liveReload?, magicHtml?, onAfterSetupMiddleware?, onBeforeSetupMiddleware?, onListening?, open?, port?, proxy?, server?, setupExitSignals?, setupMiddlewares?, static?, watchFiles?, webSocketServer? }

ValidationError: Invalid options object. Dev Server has been initialized using an options object that does not match the API schema.

这段报错信息意思是Dev Server已使用与API模式不匹配的选项对象初始化，其中明确指出是属性 ‘disableHostCheck’，于是我屏蔽了这个属性，发现能启动成功

此时我查看了之前和这次的项目的webpack的版本发现这次的版本是 webpack5 之前是webpack4，并且查看了webpack的文档发现

‘disableHostCheck’ 这个属性在webpack4中已经被删除替换，webpack5中已经不存在这个属性了，所以配置这个会报错，正确做法是替换成

devServer: {
    historyApiFallback: true,
    allowedHosts: "all"
  },

OK！
