升級到 Angular 12 & Webpack

Question

我已經使用 .NET 框架將 Angular 6 項目升級到 Angular 12。 我目前面臨2個問題。

1)

我在 package.json 中指定了構建命令：

"prodbuild": "ng build --configuration production --aot=true --output-hashing none",
"build": "ng build --output-hashing none",

我可以使用 ng build --output-hashing none 進行編譯。 但是，我無法使用 Chorme 開發工具調試代碼，源代碼顯示來自 Webpack 而不是項目的目錄結構。 我在 ts 文件中更改的代碼未在開發工具中更新。 我試圖清除緩存，刷新頁面，但沒有幫助。

2. 我之前一直在使用

   ng build --watch

什么取代了這個？ 這對於在瀏覽器中更新代碼和刷新非常方便。

這是我的 angular.json：

請指教！

Answer 1

ng build現在默認使用生產配置進行編譯。

嘗試ng build --watch --configuration development或ng serve
