问我用npm rum build报错，"indexPath" is not allowed？

Invalid options in vue.config.js: "indexPath" is not allowed

配置地址

const luOutPath = '../'

module.exports = {

baseUrl: BASE_URL,

outputDir: luOutPath + 'public/lu/dist',

indexPath: luOutPath + '../../resources/views/dashboard.blade.php',

chainWebpack: config => {

config.resolve.alias.set('@', resolve('src')). // key,value自行定义，比如.set('@@', resolve('src/components'))

set('_c', resolve('src/components')).set('_conf', resolve('config'))

},

productionSourceMap: false

}
