前端项目 启动报错？

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

看提示应该是这部分出了问题，但不知道是为啥，怎么改？

// webpack-dev-server 相关配置
  devServer: {
    host: '0.0.0.0',
    port: port,
    open: false,
    proxy: {
      // detail: https://cli.vuejs.org/config/#devserver-proxy
      [process.env.VUE_APP_BASE_API]: {
        target: `http://localhost:8989`,
        changeOrigin: true,
        pathRewrite: {
          ['^' + process.env.VUE_APP_BASE_API]: ''
        }
      }
    },
    disableHostCheck: true
  },

在chatgpt中给出的方法将disableHostCheck换成

// 在这里添加额外的选项
    allowedHosts: [
      // 允许的 IP 或域名列表
      'localhost',
      '127.0.0.1'
    ]

也是报错

回答：

options has an unknown property 'disableHostCheck'. These properties are valid:
           object { allowedHosts?, bonjour?, client?, compress?, devMiddleware?, headers?, historyApiFallback?,
host?, hot?, http2?, https?, ipc?, liveReload?, magicHtml?, onAfterSetupMiddleware?, onBeforeSetupMiddleware?, o
nListening?, open?, port?, proxy?, server?, setupExitSignals?, setupMiddlewares?, static?, watchFiles?, webSocke
tServer? }

可用的配置字段里面不包括disableHostCheck,把disableHostCheck注释了再试试
