Angular 2“在遇到静态解析符号值时出错.”运行i18n

我正在尝试运行i18n提取工具来翻译我的角度2应用程序.
但是当我试图跑步时,我得到：

错误发生在我的自定义错误处理程序中：

// Import the core angular services.
import { ErrorHandler } from '@angular/core';
// import { forwardRef } from '@angular/core';
import { Inject } from '@angular/core';
import { Injectable } from '@angular/core';

// Import the application components and services.
import { ErrorLogService } from './error-log.service';

export interface LoggingErrorHandlerOptions {
  rethrowError: boolean;
  unwrapError: boolean;
}

export var LOGGING_ERROR_HANDLER_OPTIONS: LoggingErrorHandlerOptions = {
  rethrowError: false,unwrapError: false
};

@Injectable()
export class LoggingErrorHandler implements ErrorHandler {

  private errorLogService: ErrorLogService;
  private options: LoggingErrorHandlerOptions;

  constructor(
    errorLogService: ErrorLogService,@Inject(LOGGING_ERROR_HANDLER_OPTIONS) options: LoggingErrorHandlerOptions <!--- ERROR
  ) {
    this.errorLogService = errorLogService;
    this.options = options;
  }

错误处理程序基于以下文章：
https://www.bennadel.com/blog/3138-creating-a-custom-errorhandler-in-angular-2-rc-6.htm

因此,如果您想要查看完整的代码,您可以在那里看到它.

任何人都知道为什么会抛出这个错误？

解决方法

这里只是一个疯狂的猜测：

更改

export interface LoggingErrorHandlerOptions

至

export class LoggingErrorHandlerOptions
