转换现有的angular 2项目以使用angular CLI

问题描述

我有一个不是使用ng new创建的项目(相反，我遵循了 quickstart 指导).当我在该项目中运行有角度的CLI命令(例如ng generate)时，出现以下错误消息:

I have a project that was not created using ng new (rather, I followed the quickstart guide). When I run an angular CLI command in that project (such as ng generate) I get this error message:

有没有办法将现有项目转换为angular-cli项目? (我想尝试使用它，因为它显然可以自动解决桶输入和SystemJS问题.)

Is there a way I can turn my existing project into an angular-cli project? (I wanted to try using it because it apparently automatically works around an issue with barrel imports and SystemJS.)

推荐答案

您应该能够运行ng init并按照提示进行操作.如果您需要一些指导，请查看此问题: https://github.com/angular/angular-cli/issues/755

You should be able to run ng init and follow the prompts. Have a look at this issue if you need some guidance: https://github.com/angular/angular-cli/issues/755

编辑(2017年3月13日):

ng-init已从最新版本的cli中删除. https://github.com/angular/angular-cli/pull/4628

ng-init was removed from the latest version of the angular cli.https://github.com/angular/angular-cli/pull/4628

因此，现在您需要模仿其试图完成的工作.即:

So for now you'll need to resort to mimicking what it tried to accomplish.ie:

1. 创建一个新的角度项目ng new myTemplate

1. Create a new angular projectng new myTemplate

将相关文件从新的myTemplate项目复制到现有项目:

Copy relevant files to your existing project from your new myTemplate project:

.angular-cli.jsonpackage.jsontslint.jsonsrc/polyfills.tssrc/styles.csssrc/tsconfig.json

.angular-cli.jsonpackage.jsontslint.jsonsrc/polyfills.tssrc/styles.csssrc/tsconfig.json

根据您现有应用程序的状态，您可能希望通过某种方式进行复制.我猜这就是为什么从CLI中删除该功能的原因.它实际上没有任何方法可以确切地知道您要执行的操作.

Depending on the state of your existing application you may want to copy over way more or way less. I guess this is why the feature was removed from the CLI. There isn't really any way for it to know exactly what you want it to do.
