Я обновил свой angular проект с v7 до v8.2.14, и теперь, когда я запускаю ng serve, в консоли выдается эта ошибка:
TypeError: Cannot read property 'ngInjectableDef' of undefined
at getInjectableDef (core.js:361)
at resolveNgModuleDep (core.js:30377)
at NgModuleRef_.get (core.js:31578)

Я много искал но ни одно из решений не решило мою проблему.
Это мой пакет. json

Обновление:
Работает, когда я запускаю ng build. Я получаю ошибку только при запуске ng serve.
