无法在package.json中正确指向start标记以反应js

Question

当我为特定的反应应用程序编写package.json时，它在npm上工作正常，捆绑包准备好并且渲染没有问题，但是当我创建另一个应用程序时，将我的所有代码放在子文件夹中并复制相同的包。 json为我的新反应应用程序，npm抛出错误。 好像它无法从我的包中识别出启动组件。 请帮忙。

Answer 1

只需更改入口点的路径即可。 您需要更改输入文件的路径

webpack.config.js

Answer 2

这是正确的，它对我有用。在webpack.config.js中修改条目文件。 我还必须在我的项目node-modules文件夹中添加webpack-dev-server。 你应该在开始工作时得到这个。 https://i.stack.imgur.com/Y0qZQ.png

我希望这可以帮助别人
