在使用中使用Angular 4中的node_module（网站刮板）失败

目前我正在尝试将node_module“网站刮板”[1]添加到我的Angular 4项目中。 我通过“npm install website-scraper -save”下载安装模块。 在我的组件我导入模块“导入*作为刮刀从'网站刮板'”。

到目前为止，所有东西都按预期编译 如果我现在只是添加“console.log（Scraper）”在我的组件的某处，我得到警告[3]，我的浏览器抛出错误[2]

有人可以启发我，出了什么事？ 我使用节点8.9.0和npm 5.5.1。 无论如何，我尝试多个furhter（旧）版本的节点和npm导致相同的行为。 任何帮助表示赞赏。 提前致谢。
