Question

几天前，我开始玩Ionic 2和Angular 2，但是现在当我运行“ionic start myProjectName blank --v2”时，它总是会创建一个带有v3.0.1离子框架的新项目。即使我指定“--v2”，它也会使用Ionic 3.0.1和Angular 4，但我想使用带角度2的Ionic 2，因为我认为将Ionic 3和Angular 4用于生产网络应用程序还为时尚早。< / p>

这是我的命令“$ ionic info”输出：

Your system information:

Cordova CLI: 6.5.0
Ionic Framework Version: 3.0.1
Ionic CLI Version: 2.2.2
Ionic App Lib Version: 2.2.1
Ionic App Scripts Version: 1.3.0
ios-deploy version: Not installed
ios-sim version: Not installed
OS: macOS Sierra
Node Version: v6.10.0
Xcode version: Not installed

和我的package.json依赖项阻止：

 "dependencies": {
    "@angular/common": "4.0.0",
    "@angular/compiler": "4.0.0",
    "@angular/compiler-cli": "4.0.0",
    "@angular/core": "4.0.0",
    "@angular/forms": "4.0.0",
    "@angular/http": "4.0.0",
    "@angular/platform-browser": "4.0.0",
    "@angular/platform-browser-dynamic": "4.0.0",
    "@ionic-native/core": "3.4.2",
    "@ionic-native/splash-screen": "3.4.2",
    "@ionic-native/status-bar": "3.4.2",
    "@ionic/storage": "2.0.1",
    "ionic-angular": "3.0.1",
    "ionicons": "3.0.0",
    "rxjs": "5.1.1",
    "sw-toolbox": "3.4.0",
    "zone.js": "^0.8.4"
  },

[编辑] 如果这个云帮助其他人，我也会在Ionic论坛上发布这个问题。非常感谢https://forum.ionicframework.com/t/ionic-2-with-angular2/86072/2。

Answer 1

ionic blog

根据这个，

使用CLI的2.x版仍需要--v2标志来使用最新版本的框架（当前为3.0.1）创建应用程序。如果您使用的是CLI版本（3.0.0-beta.5是最新版本），它不需要任何标记，并将使用最新版本的框架（3.0.1）生成应用程序。

因此，不再可能使用最新的v2框架（我认为是2.2.0或2.3.0）创建一个新的应用程序。它现在是1. 。或3.0.0。

Answer 2

您只需将package.json更改为旧版本

即可

"dependencies": {
  "@angular/common": "2.4.8",
  "@angular/compiler": "2.4.8",
  "@angular/compiler-cli": "2.4.8",
  "@angular/core": "2.4.8",
  "@angular/forms": "2.4.8",
  "@angular/http": "2.4.8",
  "@angular/platform-browser": "2.4.8",
  "@angular/platform-browser-dynamic": "2.4.8",
  "@angular/platform-server": "2.4.8",
  "@ionic/storage": "2.0.0",
  "ionic-angular": "2.2.0",
  "ionic-native": "2.8.1",
  "ionicons": "3.0.0",
  "rxjs": "5.0.1",
  "sw-toolbox": "3.4.0",
  "zone.js": "0.7.2"

}，

然后运行>_ npm install

用Angular 2运行Ionic 2
