升级到 Angular 9 后，在typings 文件中找不到变量 [英] After upgrade to Angular 9 cannot find variable in typings file

问题描述

我有一个对外部日志组件的引用(在 js 文件中引用)，我在typings 文件中定义了该组件

I have a reference to an external logging component (referenced in a js file), which I have defined in a typings file

typings.d.ts

declare var LogglyTracker;

我已将 Angular 应用程序从版本 8 升级到 9，现在当我运行 ng build 时，出现以下错误

I have upgraded my angular application from version 8 to 9, and now when I run ng build, I get the following error

src/app/error/loggly.service.ts 中的错误:13:29 - 错误 TS2304:找不到名称LogglyTracker".

ERROR in src/app/error/loggly.service.ts:13:29 - error TS2304: Cannot find name 'LogglyTracker'.

有谁知道解决这个问题的推荐方法是什么?此代码在 Angular 8 中运行良好.

Does anyone know what the recommended way to fix this problem is? This code worked fine in Angular 8.

@Injectable()
export class LogglyLoggerService {

// https://github.com/loggly/loggly-jslogger
private loggly: any = new LogglyTracker(); //!! Error here
}

推荐答案

对我来说，解决方案是将以下内容添加到服务文件的顶部:

Well for me the resolution was to add the following to the top of service file:

/// <reference path="../../typings.d.ts" />

reference 显然是将类型定义导入代码的另一种方式，更多信息 这里

reference is apparently another way to import type definitions into code, more info here
