[webpack-cli] Invalid options object.Webpack学习问题记录

在学习webpack中使用webpack-dev-server启动本地服务时遇到问题[webpack-cli] Invalid options object. Dev Server has been initialized using an options object that does not match the API schema.，经检索发现是因为webpack-dev-server中contentBase被废弃了，新属性是static，修改web.config.js后运行成功。

devServer: {

// contentBase: path.resolve(__dirname, 'dist')

static: 'dist'

}
