Question

有没有机会在angular4中使用angular2组件？在我的情况下，我想使用库来生成图表： https://devarchy.com/angular/ng2-nvd3，但遗憾的是它的依赖关系对我的应用来说太低了。 Aren＆＃t; t angular2组件与angular4兼容？

NPM尝试安装pck

PS。我无法降级应用程序＆＃39;图书馆 PS2。我需要这个lib，因为我的应用程序中需要多个Y轴。

我发现的唯一解决方案（不是长期的）：

转到node_modules \ webpack-dev-server \ lib并打开Server.js.

Server.prototype.checkHost = function(headers) {
    ...

    // disallow
    return false;
}

将“return false”更改为“return true”。保存并再次运行您的项目。

在Angular 2中构建的组件可以在Angular 4中使用，但在angular 2版本中使用的模块仅与该版本兼容。因此，您需要安装与angular 4版本兼容的模块的答案。
