将非 angular-cli 项目部分转换为 angular-cli（您必须在 Angular CLI 项目中才能使用生成命令）

Question

我关注/克隆了这个github repo：

我做到了：npm install

然后我做了：npm start

项目可以运行。

然后我想在这个项目中添加一个新组件。我用：ng generate component my-foo-component

但我得到了这个错误：

您必须在 Angular CLI 项目中才能使用生成命令

我在 stackoverflow 中找到了一些与我的问题相关的帖子，我尝试过，但没有运气。如何解决我的问题。看来这个项目不是由 Angular cli 创建的，所以我不能使用如下命令：ng generate ...

我检查了我的 package.json，我可以看到 angular cli 作为依赖项？

我的package.json：

Answer 1

如果您只想将angular-cli 用于像

这样的世代

• ng g 组件 my-new-component
• ng g 指令 ​​my-new-directive
• ng g pipe my-new-pipe
• ng g service my-new-service
• ng g class my-new-class
• ng g guard my-new-guard
• ng g interface my-new-interface
• ng g enum my-new-enum
• ng g module my-module

而不是像

这样的动作

• ng 构建
• ng 服务
• 等等……

您可以执行以下操作：

1. 确保位于应用的根目录（node_modules 文件夹 位于）
2. 运行npm install @angular/cli，即使您已全局安装了angular cli，也要运行它，您的package.json 文件中需要此条目

3. 使用非常少的设置创建一个名为 .angular-cli.json 的文件 喜欢：

   {
     "$schema": "./node_modules/@angular/cli/lib/config/schema.json",   
     "project": {
       "name": "angular-starter"   
     },   
     "apps": [
       {
         "root": "src",
         "index": "index.html",
         "main": "main.ts"
       }   
     ],   
     "defaults": {
       "styleExt": "css"   
     } 
   }
   

此时你应该可以运行了

ng c my-new-component

如果你没有全局安装 ng 命令，你可以运行它

node_modules/.bin/ng c my-new-component

确保探索所有可用的生成选项：

• https://github.com/angular/angular-cli/wiki/generate-component
• https://github.com/angular/angular-cli/wiki/generate-directive
• 等... 可通过ANGULAR CLI git hub page或通过ANGULAR CLI git hub page获得

Answer 2

要生成组件，您必须进入项目文件夹 如果您使用的是 Visual Studio Code，那么

 Go to 
1-View
2-Integrated Terminal
or ( CTRL+` )
use the Integrated Terminal for to generate component

ng generate component my-foo-component (or)
ng g component my-foo-component

如果您使用的是其他编辑器，那么 使用你的命令提示符

Note:_
in command prompt you most be inside project folder

Answer 3

要在项目内生成组件、服务或管道，您必须位于所需文件夹内。例如，如果要为用户组件生成管道，则必须位于用户文件夹内。

在生成组件使用方面：

cd project
cd src/app

然后

ng generate component my-foo-component
