reactjs - react : npm start works, npm run build 抛出 ELIFECYCLE 错误(errno 1)

Question

我有一个 React 应用程序(使用 create-react-app 创建)。npm start最初工作并且仍在工作。
当我跑 npm run build最初几天前部署到 Firebase 托管，它工作。
然而，今天，我注意到，虽然npm start仍然有效，npm run build将抛出以下错误:

npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! fellon@0.1.0 build: `react-scripts build`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the fellon@0.1.0 build script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

我正在使用节点:v14.5.0/npm:6.14.5/react-scripts:3.4.1/webpack:4.42.0
这个 React 应用的代码是: https://github.com/travelingaries/Fellon
我尝试过但没有用的一些方法是:

npm cache clean --force => 删除 node_modules 和 package-lock.json => npm install => npm run build

yarn build而不是 npm run build

克隆整个项目代码 => npm install在新文件夹中 => npm run start

更新 node 和 npm 版本，然后尝试以上步骤

确保在环境变量的PATH中添加system32(确认已经添加)

我整天都在摆弄这个问题，我几乎别无选择。
如果有人可以为这个问题提出一个可行的解决方案，那将意味着很多。
非常感谢您提前!

就像在 Muhammad Usama Ashraf 的评论中一样，这是一个简单的语法错误，在我的案例中未被发现。
更改 以解决此问题。
