npm run build & npm start 不工作，react app

Question

我是一个新的react学生，没有其他地方可以问这个问题，也无法自己解决，因为我真的很困惑，我什至不知道如何正确地把这个问题放在一起。我正在按照反应课程的说明进行操作。

我安装了node.js，创建了一个新的项目文件夹，然后在终端我写了create react-app .一切正常，然后写了npm run build和npm start，但都没有工作。

这是npm run build 的错误消息：

这是npm start的代码

我发现了一些有用的东西。 使用命令节点node node_modules/react-scripts/scripts/start.js 与npm start 执行相同的操作，但我不知道这里有什么问题。为我工作。来源：https://github.com/facebook/create-react-app/issues/8221

首先基于“create-react....”创建您的项目 您必须使用确切的命令“npx create-react-app 'yournameProject'” 然后在文本编辑器（如可视代码）中打开您的文件夹并运行以下命令 - >“npm start” 它不应该给你错误

关于你的问题：我认为你已经踩到了一些东西

所以尝试先使用“npm i”然后“npm start”
