[英]Angular-CLI Error: Return type of public method from exported class has or is using name 'ErrorObservable' from external module but cannot be named
[英]Angular2 Error: Return type of public method from exported class has or is using private name
在最初使用非CLI版本的Angular 2构建应用程序的工作版本之后,我正在使用Angular-CLI构建Angular 2应用程序。令我惊讶的是,某些代码在我的非CLI中不是问题应用程序版本已成为我的Angular-CLI版本的问题。 综上所述,除了我遇到的最后一个错误,我已经解决了所有问题。
这是我收到的错误消息:
未捕获的错误:模块构建失败:错误:/Users/fdr/Documents/rds/rds/cli-rds/src/app/ui/generate-field.component.ts(340,48):从导出返回公共方法的类型类具有或正在使用私有名称“提示”。)
这是导致错误的问题文件:
import { Component, Input, Output, EventEmitter, OnInit, AfterViewInit, ElementRef, ViewChild } from '@angular/core';
import { EventHandler } from '../app.event-handler';
import '../app.utils';
@Component({
selector: 'app-generate-field',
templateUrl: 'app/ui/generate-field.component.html',
styleUrls: ['app/ui/generate-field.component.css']
})
export class GenerateField extends EventHandler
{
public get hasFocus(): boolean
{
return this._hasFocus;
}
@Input() delay: number = 300;
@ViewChild('inputField') private inputField: ElementRef;
@ViewChild('suggestionField') private suggestionField: ElementRef;
@Input() public value: string;
@Output() private valueChange: EventEmitter<string> = new EventEmitter<string>();
@Output() public keyup: EventEmitter<KeyboardEvent> = new EventEmitter<KeyboardEvent>();
@Output() public focus = new EventEmitter<KeyboardEvent>();
@Output() public blur = new EventEmitter<KeyboardEvent>();
private inlineSuggestion: string;
private suggestions: ISuggestion[];
@Input() public options: string[];
@Output() private optionsChange: EventEmitter<string[]> = new EventEmitter<string[]>();
private isDirty: boolean = false;
private _hasFocus: boolean = false;
constructor(myElement: ElementRef)
{
super();
this.defineObservableProperty('value');
this.defineObservableProperty('isDirty');
this.defineObservableProperty('suggestions');
this.defineObservableProperty('options');
this.addPropertyListener('isDirty', function ()
{
if (this.isDirty == false)return;
var delay = this.delay ? this.delay : 500;
var self = this;
setTimeout(function ()
{
self.updateSuggestions();
this.isDirty = false;
}.bind(this), delay);
}.bind(this));
this.addPropertyListener('value', (): void=>
{
this.valueChange.emit(this.value);
this.isDirty = true;
});
this.addPropertyListener('suggestions', (): void=>
{
this.updateInlineSuggestion();
});
this.addPropertyListener('options', ()=>
{
this.optionsChange.emit(this.options);
});
}
//--------------------------------------------------------

/**
* Evaluates value and updates the list of suggestions
*/
public updateSuggestions(): void
{
// Update suggestions
this.suggestions = this.generateSuggestions(this.value);
}
/***
* Updates the inline suggestion that appears on the text field
*/
private updateInlineSuggestion(): void
{
// Clear inline if there are no suggestions
if (this.suggestions.length == 0)
{
this.inlineSuggestion = '';
return;
}
// Show first option inline
this.inlineSuggestion = this.suggestions[0].value;
var x = this.inputField.nativeElement.selectionStart;
var y = this.inputField.nativeElement.selectionEnd;
this.suggestionField.nativeElement.selectionStart = x;
this.suggestionField.nativeElement.selectionEnd = y;
this.inputField.nativeElement.selectionStart = x;
this.inputField.nativeElement.selectionEnd = y;
this.suggestionField.nativeElement.scrollLeft = x;
}
private onFocus(): void
{
this._hasFocus = true;
// Forward event
this.focus.emit();
}
private onBlur(): void
{
this._hasFocus = false;
// Forward event
this.blur.emit();
}
interface ISuggestion
{
word: string;
match: string;
value: string;
}
尝试在代码的最后部分添加“ 导出接口ISuggestion”,以便也导出ISuggestion。
尝试在任何方法之后添加:。 我遇到了同样的问题,添加任何东西后都解决了。
