Angular导入外部javascript文件，没有导出的成员和编译错误

Question

I am writing an angular component and got a open source module working with npm install. Now I made some some changes and want to import the javascript file like so

import { ModuleName } from './../../ModuleFolder/ModuleName';

When I place the cursor above the ModuleName inside the bracket, I see the highlighted red error saying Module has not export member ' ModuleName ';

In my ts code, I have referenced the Module like so

object: ModuleName ; which is also complaining.

I google and the post says using npm install but I don't want to add this module to my node_module list. I am moving the folder out to make my customization.

I also tried the following but it is not working

import   './../../ModuleName.bundle.min.js';

I am wondering does the name of the Module needs to be registered somewhere to be able to reference it in my component?

Thanks for any help.

I got external libraries working in Angular by following the following links

Use 'declare' after the import statements

declare const _moduleName;

For example: I am using Swiper.js library using cdn. In my angular component, I refer it using a declare keyword.

declare const Swiper;

var mySwiper = new Swiper('.swiper-container', { /* ... */ });
