Я пытаюсь запустить .NET Core 2 / Angular 6 SPA. Я создал приложение Angular 5, используя «dotnet new angular», а затем приступил к обновлению, используя это руководство из angular.io. Когда я закончил обновление, я попытался запустить приложение, используя «запуск по сети», и я получил ужасную страницу с ошибкой:
Произошло необработанное исключение при обработке запроса.
AggregateException: произошла одна или несколько ошибок. (Одна или несколько ошибок
произошло. (Сценарий NPM 'start' вышел без указания на то, что
Angular CLI слушал запросы. Вывод ошибки был: неизвестно
опция: '--extractCss'
InvalidOperationException: сценарий NPM 'start' завершился без указания того, что Angular CLI прослушивал запросы. Вывод ошибки был: Неизвестная опция: '--extractCss'
Подумав, возможно, я пропустил шаг во время обновления, я попробовал второй раз и получил ту же ошибку.
Вот шаги, которые я предпринял после создания приложения:
npm install -g @angular/cli
npm install @angular/cli
ng update @angular/cli
ng update @angular/core
npm install --save @angular/material @angular/cdk @angular/animations hammerjs
npm install -g rxjs-tslint
rxjs-5-to-6-migrate -p src/tsconfig.app.json
Я использую Node версии 9.4.0 и .Net Core 2.1.200 в Windows 10 (1703) Enterprise.
Есть идеи как это исправить? Вот полная трассировка стека:
