ng cli和angular更改版本最佳实践时如何更新应用程序 [英] how to update an app when ng cli and angular change version best practice

问题描述

当ng cli 1.5和angular 5像现在这样的ng cli和angular更改版本时，如何更新应用程序?

How to update an app when ng cli and angular change version like now with ng cli 1.5 and angular 5 ?

我的目标是拥有一个现有的项目，例如，角度为4和ng cli 1.4，更新为角度5，并由ng cli建造一个脚手架. (我不知道在这种情况下，但是脚手架有时已经改变了，所以我想要全新的脚手架)

My goal is to have an existing project with for instance angular 4 and ng cli 1.4,updated to angular 5 and the one scaffold built by ng cli. (I don't know in this case but also the scaffold have sometime changed so I want the brand new scaffold)

一种替代方法应该是使用融合.

An alternative should be using meld.

我正在寻找最佳方法/做法，因为现在我正在遵循所有这些步骤.

I'm looking for a best way/practice because right now I'm following all of these steps.

现在，如果可能的话，我会使用nvm更新节点版本，例如

By now I update if possible the node version with nvm so for instance

• nvm install v9.0.0

nvm use v9.0.0

npm install -g @angular/cli

ng new myproject

覆盖src和Assets文件夹

overwrite the src and assets folders

更新package.json

复制.stylelintrc

删除package-lock.json

npm install

您会看到很多工作，而且也容易出错，所以我想知道是否有更聪明的方法来进行更新.

As you can see a lot of work and also error prone so I'm wondering if there is a smarter way to do the update.

真正的问题是外部库 例如OpaqueToken:(

The really problems are the external lib for instance for the OpaqueToken :(
