错误 TS2300：Angular 中的重复标识符 \'type\'。在运行 ng build 时

Question

错误：node_modules/@firebase/auth-compat/dist/auth-compat/index.d.ts:53:10 - 错误 TS2300：标识符“类型”重复。

尝试构建角度代码, 我在下面命令错误.

 import { type User, type Unsubscribe, type ActionCodeInfo, type UserCredential, type Auth, type IdTokenResult, type MultiFactorError, type MultiFactorResolver, type PopupRedirectResolver, type Dependencies, type AuthCredential, type ApplicationVerifier, type ConfirmationResult, type AuthProvider, type MultiFactorUser, type NextOrObserver, type ErrorFn, type CompleteFn, type ActionCodeSettings, type Persistence, type PhoneAuthCredential } from "@firebase/auth";
            ~~~~


Error: node_modules/@firebase/auth-compat/dist/auth-compat/index.d.ts:53:10 - error TS2300: Duplicate identifier 'type'.

有时我会出错所有 Firebase 兼容像这样的文件数据库兼容、存储兼容等.

这是我的包.json文件

我试着减少9.0.0 和 ^7.0.0 中的 firebase 和 @angular/fire 版本基于角度版本.但这是行不通的。

我参考这个链接更改版本。 https://www.npmjs.com/package/@angular/fire

帮助解决这个问题。

我尝试以多种方式解决该问题，但我无法解决这个问题。

我期待尽快解决问题。

您的导入语句中不需要单词 type。试试这个：

import {
    User,
    Unsubscribe,
    ActionCodeInfo,
    UserCredential,
    Auth,
    IdTokenResult,
    MultiFactorError,
    MultiFactorResolver,
    PopupRedirectResolver,
    Dependencies,
    AuthCredential,
    ApplicationVerifier,
    ConfirmationResult,
    AuthProvider,
    MultiFactorUser,
    NextOrObserver,
    ErrorFn,
    CompleteFn,
    ActionCodeSettings,
    Persistence,
    PhoneAuthCredential
} from "@firebase/auth";
