这是我的第一个有角度的项目，我一直在使用内置服务器进行运输，偶尔进行构建以推送到服务器-现在我正在尝试--prod构建...而Im出现编译错误。

通过大量的阅读，我已经设法解决了大多数问题，并且我了解AOT的需求，但是这一错误使我感到困惑

我通过应用反复使用此代码来启动表单，

<form novalidate="novalidate"
    autocomplete="off"
    [formGroup]="form"
    (submit)="form.valid && submitForm()" >

但是在其中一些模板上

x.component.html(6,3): : Expected 1 arguments, but got 0.

第6行是：（submit）=“ form.valid && SubmitForm（）”>

========注：我已将代码精简化

and included it here, so you see EXACTLY what is there...

no extrapolating or generalizing.

Builds fine in dev mode

cli v（1.6.0）

我仍然遇到相同的错误-user-form.component.html（6,4）：期望有1个参数，但得到0。

所以我想我会提供完整的组件和模板。

component.ts

import { Component, OnInit, EventEmitter, Output } from '@angular/core';
import { FormBuilder, FormGroup, FormControl, NgForm, NgControl, Validators } from '@angular/forms';
import { AbstractControl } from '@angular/forms/src/model';
import { ValidationErrors } from '@angular/forms/src/directives/validators';

import { get } from 'lodash';

@Component({
    selector: 'user-form',
    templateUrl: './user-form.component.html',
})

export class UserFormComponent implements OnInit {

    form: FormGroup;
    loading = false;
    submitAttempted = false;

    constructor(
    ) { }

    get formDisabled () {
        return this.loading === true;
    }

    get xStatus () {
        const field = this.form.get('x');
        if (!field.touched) {
            return '';
        }
        if (field.errors && field.errors.required) {
            return 'This field is required';
        }
    }


    get formModel () {
        return {
            x: this.form.get('x').value
        }
    }

    ngOnInit() {
        this.form = new FormGroup({
            x: new FormControl(
                {
                    value: 'x',
                    disabled: this.formDisabled,
                },
                [
                    Validators.required
                ]
            )
        })
    }

    resetForm () {
        this.form.get('x').markAsUntouched();
        this.submitAttempted = false;
    }

    submitForm(form: NgForm) {
        console.log( this.form );
    }

    showError (fieldName: string) {
        const field = this.form.get(fieldName);
        return field.invalid && (field.touched || this.submitAttempted);
    }

}

template.ts（user-form.component.html）

<form 
    novalidate="novalidate"
    autocomplete="off"
    [formGroup]="form"
    (ngSubmit)="submitForm()" >

    <label class="input" [class.state-error]="showError('x')">
        <input type="text" name="x" placeholder="x" formControlName="x" />
        <div *ngIf="xStatus" [innerHTML]="xStatus | safeHtml"></div>
    </label>


    <button type="submit" class="btn btn-primary" (click)="submitAttempted = true">
        <i *ngIf="loading" class='fa fa-spinner fa-spin '></i>
        {{ loading ? 'Saving' : 'Add x' }}
    </button>

</form>
