我试图重新启动我的旧项目并遇到一些JS意大利面。如果有人能给我一些关于哪个包破坏了什么的线索，我将非常感激。运行npm run build后，我收到此错误：
ERROR in ./src/polyfills.ts

这是我的polyfills.ts文件的样子：
import 'core-js/client/shim';
import 'reflect-metadata';
require('zone.js/dist/zone');
import 'ts-helpers';
if (process.env.ENV === 'build') {
// Production
} else {
// Development
Error['stackTraceLimit'] = Infinity;
require('zone.js/dist/long-stack-trace-zone');
}
这段代码在1-2个月前完成了所有工作，但现在似乎有些事情会导致休息。有任何想法吗？这是我的package.json以供参考：
