关键字'private'被保留（35:12）您可能需要一个合适的加载程序来处理此文件类型

Question

我在Angular 5应用程序中遇到了一个奇怪的问题。错误堆栈如下。

无法编译。

./src/app/registration/registration.component.ts模块解析失败： 关键字“私人”被保留（35:12）您可能需要适当的 加载器来处理此文件类型。 | }; | } |构造函数（私有， fb，FormBuilder）; | {| this.form = fb.group（{@ ./src/app/app.module.ts 16：0-78 @ ./src/main.ts @ multi webpack-dev-server/client？http://0.0.0.0:0 ./src /main.ts

这里是我的代码。

export class RegistrationComponent implements OnInit { 

    form; 
    constructor(private fb: FormBuilder) { 
    this.form = fb.group({ 
     firstName: ['', Validators.required], 
     lastName: ['', Validators.required], 
     email: ['', [Validators.required, isEmailValid('email')]], 
     password: ['', Validators.required], 
     confirmPassword: ['', Validators.required] 
    }, { validator: compareValidator('password', 'confirmPassword') }); 
    } 

    function compareValidator(control1, control2) { 
    return form => { 
     if (form.controls[control1].value !== form.controls[control2].value) { 
     return { compareResult: true }; 
     } 
    } 
    } 

    function isEmailValid(control) { 
    return control => { 
     var regex = /^(([^<>()\[\]\\.,;:\s@"]+(\.[^<>()\[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/ 
     return regex.test(control.value) ? null : { invalidEmail: true }; 
    } 
    } 

    ngOnInit() { 
    } 

} 

谁能帮我找到什么是问题？以任何机会，如果你需要看我的包版本，我附上我的package.json文件。

有时候一个小问题可能会让你挠头，这是一种类型。我不知道为什么我犯了这么小的错误。只是在班级之外移除这两个功能解决了问题。只需与其他可能以相同情况结束的人分享即可。

export class RegistrationComponent implements OnInit { 

    form; 
    constructor(private fb: FormBuilder) { 
    this.form = fb.group({ 
     firstName: ['', Validators.required], 
     lastName: ['', Validators.required], 
     email: ['', [Validators.required, isEmailValid('email')]], 
     password: ['', Validators.required], 
     confirmPassword: ['', Validators.required] 
    }, { validator: compareValidator('password', 'confirmPassword') }); 
    } 

    ngOnInit() { 
    } 

} 

function compareValidator(control1, control2) { 
    return form => { 
    if (form.controls[control1].value !== form.controls[control2].value) { 
     return { compareResult: true }; 
    } 
    } 
} 

function isEmailValid(control) { 
    return control => { 
    var regex = /^(([^<>()\[\]\\.,;:\s@"]+(\.[^<>()\[\]\\.,;:\s@"]+)*)|(".+"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/ 
    return regex.test(control.value) ? null : { invalidEmail: true }; 
    } 
} 

如果删除关键字“功能”和使用定义在类中的功能，你会isEmailValid未定义得到一个错误。
