使用角度2而不是角度4使用角度cli

Question

如何使用角度cli而不是角度4創建角度2應用？

https://github.com/angular/angular-cli

我的package.json：

"dependencies": { 
    "@angular/animations": "^4.0.0", 
    "@angular/common": "^4.0.0", 
    "@angular/compiler": "^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", 
    "@angular/router": "^4.0.0", 
    "core-js": "^2.4.1", 
    "rxjs": "^5.1.0", 
    "zone.js": "^0.8.4" 
    }, 
    "devDependencies": { 
    "@angular/cli": "1.1.1", 
    "@angular/compiler-cli": "^4.0.0", 
    "@angular/language-service": "^4.0.0", 
    "@types/jasmine": "2.5.45", 
    "@types/node": "~6.0.60", 
    "codelyzer": "~3.0.1", 
    "jasmine-core": "~2.6.2", 
    "jasmine-spec-reporter": "~4.1.0", 
    "karma": "~1.7.0", 
    "karma-chrome-launcher": "~2.1.1", 
    "karma-cli": "~1.0.1", 
    "karma-jasmine": "~1.1.0", 
    "karma-jasmine-html-reporter": "^0.2.2", 
    "karma-coverage-istanbul-reporter": "^1.2.1", 
    "protractor": "~5.1.2", 
    "ts-node": "~3.0.4", 
    "tslint": "~5.3.2", 
    "typescript": "~2.3.3" 
    } 

我試圖改變角度的版本，但它仍然無法正常工作

Answer 1

在你的package.json - >依賴性陣列變化角版本2.4.1和重建您的項目。

詳細答案： -

1）使用Cli創建新項目。

ng new my-newapp 

2）改變目錄

cd my-newapp 

3）更新的package.json - >依賴關係。角版本更改爲2.4.1和更改路由器3.4.1

例如： -

{ 
    "name": "my-newapp", 
    "version": "0.0.0", 
    "license": "MIT", 
    "scripts": { 
    "ng": "ng", 
    "start": "ng serve", 
    "build": "ng build", 
    "test": "ng test", 
    "lint": "ng lint", 
    "e2e": "ng e2e" 
    }, 
    "private": true, 
    "dependencies": { 
     "@angular/common": "2.4.1", 
    "@angular/compiler": "2.4.1", 
    "@angular/compiler-cli": "2.4.1", 
    "@angular/core": "2.4.1", 
    "@angular/forms": "2.4.1", 
    "@angular/http": "2.4.1", 
    "@angular/platform-browser": "2.4.1", 
    "@angular/platform-browser-dynamic": "2.4.1", 
    "@angular/router": "3.4.1", 
    "@angular/upgrade": "2.4.1", 
    "@angular/material": "2.0.0-beta.0", 
    "bootstrap": "^3.3.7", 
    "concurrently": "^3.1.0", 
    "core-js": "^2.4.1", 
    "hammerjs": "^2.0.8", 
    "reflect-metadata": "^0.1.9", 
    "rxjs": "^5.0.2", 
    "systemjs": "^0.19.41", 
    "zone.js": "^0.7.4" 
    }, 
    "devDependencies": { 
    "@angular/cli": "1.0.0", 
    "@angular/compiler-cli": "^4.0.0", 
    "@types/jasmine": "2.5.38", 
    "@types/node": "~6.0.60", 
    "codelyzer": "~2.0.0", 
    "jasmine-core": "~2.5.2", 
    "jasmine-spec-reporter": "~3.2.0", 
    "karma": "~1.4.1", 
    "karma-chrome-launcher": "~2.0.0", 
    "karma-cli": "~1.0.1", 
    "karma-jasmine": "~1.1.0", 
    "karma-jasmine-html-reporter": "^0.2.2", 
    "karma-coverage-istanbul-reporter": "^0.2.0", 
    "protractor": "~5.1.0", 
    "ts-node": "~2.0.0", 
    "tslint": "~4.5.0", 
    "typescript": "~2.2.0" 
    } 
} 

4）重新安裝所有組件（可選： - 前執行這個命令，你可以刪除節點模塊文件夾）

npm install 

5）啓動瀏覽器

ng serve 

注： - 在我的系統同時執行納克服務我通過添加一個空行到app.module.ts面臨的問題

ERROR in AppModule is not an NgModule 

你解決這個問題。
