将现有的Angular2 RC2应用升级到RC4需要哪些步骤？我已经更新了我的package.json文件（见下文），并在根文件夹上运行了npm update，但它仍然引用RC2中node modules文件夹中的旧版本角度包。
我检查了更改日志和发布说明并搜索了谷歌但无济于事。应用程序运行但在引用与RC2无效的新ngModel相关表单功能时崩溃。我试图更新到RC4以使用新的表单模块来查看是否能解决我的基础表单问题。

您可以在项目目录中执行override func viewDidLoad() {
super.viewDidLoad()

controller.searchBar.sizeToFit()
self.tableView.tableHeaderView = controller.searchBar
return controller
})()
get{(value) in
self.values = value
for ele in self.values{
if self.username != ele["username"] as! String{
}
}
}
self.tableView.reloadData()
NSNotificationCenter.defaultCenter().addObserver(self, selector: #selector(serviceBoard.methodhandlingTheNotificationEvent), name:"NotificationIdentifier", object: nil)

而不是更新吗？
