我有一个有效的Django项目，并试图使用Angular2。我是Angular2的新手。当我尝试从不同的文件加载路由时，我收到以下错误。此外，早些时候我发现routerLink已在浏览器中更改为routerlink。这是预期的变化吗？
Error: TypeError: Cannot read property 'length' of undefined

我已经google了很多，发现这是一些有角度的版本的问题。这是我的package.json文件：

我到目前为止遇到的许多错误都是由于package.json或npm和node中的错误版本造成的。我一直在学习一些教程和示例，我可以学习Angular架构和语法，但如果有人能够正确地指导我在哪个版本中使用哪种语法，我将不胜感激。
