将常规npm组件装入webpack/角cli [找不到模块]

Question

大家好，亲爱的网友们，

如何使角CLI (@角形/cli)找到像“文件保护程序”这样的“常规npm包”，以便我可以使用那里提供的saveAs()-function？我创建了一个初始的，最小的项目与角cli，安装了文件保护程序，并尝试了以下，两者都没有工作。

import {Component, OnInit} from '@angular/core';
import {saveAs} from 'file-saver';
//import saveAs from 'file-saver'; didn't worked as well

@Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {
    ngOnInit(): void {
        saveAs("file.txt", new Blob());
    }

    title = 'app works!';
}

未找到多脚本加载程序/src/~/file-saver/FileSaver.js模块中的错误:错误:无法解析C中的'C:\Users*\Desktop\ng-cli-playground\src\node_modules\file-saver\FileSaver.js‘：\Users*\Desktop\ng-cli-游乐场@ multi loader！./src/~/fileSaver.js/FileSaver.js C:/Users/*/Desktop/ng-cli-playground/src/app/app.component.ts中的错误(2,22)：找不到模块‘文件保护程序’)。

我的cli配置

                "service": true
            }
        }
    }
}

PS:我已经用angular2编程了7个月了，但我以前经常用systemJS编程。无论如何，我发现这真的很难理解所有的建筑-，装载-和捆绑-工具的工作原理。提前谢谢！

它似乎是从以下错误中查看您的src文件夹：

C:\Users*\Desktop\ng-cli-playground\src\node_modules\file-saver\FileSaver.js

尝试：

"scripts": [
     "../node_modules/file-saver/FileSaver.js"
      ]
