React：npm开始工作，npm运行构建抛出ELIFECYCLE错误（errno 1）|软件开发问答库

我有一个React应用（使用create-react-app创建）。

npm start最初已经起作用，现在仍在起作用。

几天前我最初运行npm run build部署到Firebase托管时，它就可以了。但是，今天，我注意到npm start仍然有效，但npm run build将引发以下错误：

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

此React应用的代码为：https://github.com/travelingaries/Fellon

我尝试过但不起作用的一些方法是：

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
将整个项目代码=> npm install克隆到新文件夹=> npm run start
更新节点和npm版本，然后尝试上述步骤
确保将system32添加到环境变量的PATH中（确认已添加）

我整天都在摆弄这个问题，而且我几乎没有其他选择。如果有人可以为这个问题提出可行的解决方案，那将意味着很多。提前非常感谢您！
