预渲染Angular Universal应用程序时生成服务工作线程时出错

Question

在运行npm run prerender之后，我得到以下错误

× Service worker generation failed.
host.exists is not a function
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! personal-website@0.0.0 prerender: `ng run personal-website:prerender && cpx proxy-server.js dist/server`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the personal-website@0.0.0 prerender script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.

npm ERR! A complete log of this run can be found in:
npm ERR!     C:\Users\milanfc\AppData\Roaming\npm-cache\_logs\2021-03-13T18_41_31_643Z-debug.log

如果我运行ng build --prod，则生成服务工作线程时没有任何问题。我能做些什么来修复这个错误？

尝试npm i @angular/service-worker
