在生產中編譯時出錯構建jhipster

Question

在java angular應用程序中，當我使用命令編譯時

mvnw -Pprod
mvnw -Pprod package

它給了我以下錯誤，我不明白我是如何解決它們的。 我想在生產環境中使用它。

這是出現的編譯錯誤日志

在你的Angular應用程序的npm構建期間，有一行說明ERROR

[INFO] ERROR in src/main/webapp/app/account/cassa/cassa.component.ts(8,1): error TS1202: Import assignment cannot be used when targeting ECMAScript modules. Consider using 'import * as ns from "mod"', 'import {a} from "mod"', 'import d from "mod"', or another module format instead.

嘗試修復它，它應該編譯，或者至少你會得到另一個錯誤
