我已经使用create-react-app创建了一个react应用，当我第一次尝试使用npm run build构建它时，它运行良好。但是，经过几天的尝试，当我尝试运行相同的命令后，我面临以下问题。

我一直在StackOverflow中四处寻找，但似乎找不到与我的问题类似的东西。通常会有一些特定的错误消息，但我看不到。
这是我的package.json：

我发现了问题。 package.json中缺少react-scripts软件包。
要修复此问题，我运行了以下命令来安装它：
npm install react-scripts --save
完成后，执行npm运行脚本构建就可以正常工作。

您可以在package.json中使用此代码
“脚本”：{ “ start”：“反应脚本开始”， “ build”：“反应脚本--max_old_space_size = 4096建立”， “ test”：“反应脚本测试”， “ precommit”：“ lint-staged” }
