我是node和npm的新手。我一直在尝试编译我在GitHub上找到的这个Medication提醒应用程序（https://github.com/marshallmurphy/Web-Apps/tree/master/Medication%20Reminder%20React%20App），但是npm一直产生错误。我试过“npm start”并运行“webpack”但没有运气。如何在终端中编译和运行此文件？
运行npm start时出现以下错误：
Dantes-MBP:Medication Reminder React App dantegreyson$ npm start

我尝试按照建议全局安装webpack，但现在收到以下错误：
Dantes-MBP:Medication Reminder React App dantegreyson$ npm start

> webpack-dev-server

答案 0 :(得分：2)
如果您在脚本部分查看 package.json ，您将看到它尝试运行的内容
"start": "webpack-dev-server"。因此，您应该全局安装webpack-dev-server
sudo npm install webpack-dev-server -g应该为你做所有的魔法。
更新
确保您运行npm install命令
