当我调用this.disabledButton函数时,它抛出一个错误,说“类型'() => boolean‘is not assignable to type 'boolean'”。this.onClearAllUserButton}> </Button>定义的函数:
private disabledButton= (): boolean
isAuthenticated(): boolean var token = localStorage.getItem(ACCESS_TOKEN_KEY); }Type 'string | boolean | null' is not assignable to type'boolean'.Type 'null' is not assignabl
当我迁移数据时,我得到这个错误: **django.db.utils.ProgrammingError: cannot cast type timestamp with time zone to booleanALTER COLUMN "active" TYPE boolean USING "active"::boolean** 我已经阅读了一些PostgreSQL文档,并重新阅读了我的代码,但是由于这个错误
: Observable<boolean>;
this.isSomethingPresent$ = this.store.select(selectIsSomethingPresent);
} 我得到了这个错误: Type 'Observable<boolean | "">' is not assignable to type 'Observable<boolean>'.
完成所有操作后,我得到了以下代码: private userCurrentState = new BehaviorSubject<boolean>(this.tokenAuthService.isSignedin()); 此错误消息 Argument of type 'boolean | undefined' is not assignable to parameter of type 'boolean'.
