最近看到一篇用Visual Studio Code開發Angular2的文章,也是一篇入門教程,地址爲:使用Visual Studio Code開發Angular 2專案。這裏循序漸進的作了一遍,感受很方便,而且沒有遇到樓主的一些問題,應該是安裝環境有些不一樣。這裏只爲記錄一下。再次感謝!css
1、隨便新建一個目錄,這裏爲:F:\Visual Studio Code\angular2_1,並用Visual Studio Codehtml
2、依次新建以下四個文件,參考https://angular.cn/docs/ts/latest/quickstart.htmlnode
package.json 用來標記出本項目所需的 npm 依賴包。web
tsconfig.json 定義了 TypeScript 編譯器如何從項目源文件生成 JavaScript 代碼。typescript
typings.json 爲那些 TypeScript 編譯器沒法識別的庫提供了別的定義文件。npm
systemjs.config.js 爲模塊加載器提供了該到哪裏查找應用模塊的信息,並註冊了全部必備的依賴包。 它還包括文檔中後面的例子須要用到的包。json
1 { 2 "name": "angular-quickstart", 3 "version": "1.0.0", 4 "scripts": { 5 "start": "tsc && concurrently \"tsc -w\" \"lite-server\" ", 6 "lite": "lite-server", 7 "postinstall": "typings install", 8 "tsc": "tsc", 9 "tsc:w": "tsc -w", 10 "typings": "typings" 11 }, 12 "license": "ISC", 13 "dependencies": { 14 "@angular/common": "~2.0.1", 15 "@angular/compiler": "~2.0.1", 16 "@angular/core": "~2.0.1", 17 "@angular/forms": "~2.0.1", 18 "@angular/http": "~2.0.1", 19 "@angular/platform-browser": "~2.0.1", 20 "@angular/platform-browser-dynamic": "~2.0.1", 21 "@angular/router": "~3.0.1", 22 "@angular/upgrade": "~2.0.1", 23 "angular-in-memory-web-api": "~0.1.1", 24 "bootstrap": "^3.3.7", 25 "core-js": "^2.4.1", 26 "reflect-metadata": "^0.1.8", 27 "rxjs": "5.0.0-beta.12", 28 "systemjs": "0.19.39", 29 "zone.js": "^0.6.25" 30 }, 31 "devDependencies": { 32 "concurrently": "^3.0.0", 33 "lite-server": "^2.2.2", 34 "typescript": "^2.0.3", 35 "typings":"^1.4.0" 36 } 37 }
1 { 2 "compilerOptions": { 3 "target": "es5", 4 "module": "commonjs", 5 "moduleResolution": "node", 6 "sourceMap": true, 7 "emitDecoratorMetadata": true, 8 "experimentalDecorators": true, 9 "removeComments": false, 10 "noImplicitAny": false 11 } 12 }
1 { 2 "globalDependencies": { 3 "core-js": "registry:dt/core-js#0.0.0+20160725163759", 4 "jasmine": "registry:dt/jasmine#2.2.0+20160621224255", 5 "node": "registry:dt/node#6.0.0+20160909174046" 6 } 7 }
1 /** 2 * System configuration for Angular samples 3 * Adjust as necessary for your application needs. 4 */ 5 (function (global) { 6 System.config({ 7 paths: { 8 // paths serve as alias 9 'npm:': 'node_modules/' 10 }, 11 // map tells the System loader where to look for things 12 map: { 13 // our app is within the app folder 14 app: 'app', 15 // angular bundles 16 '@angular/core': 'npm:@angular/core/bundles/core.umd.js', 17 '@angular/common': 'npm:@angular/common/bundles/common.umd.js', 18 '@angular/compiler': 'npm:@angular/compiler/bundles/compiler.umd.js', 19 '@angular/platform-browser': 'npm:@angular/platform-browser/bundles/platform-browser.umd.js', 20 '@angular/platform-browser-dynamic': 'npm:@angular/platform-browser-dynamic/bundles/platform-browser-dynamic.umd.js', 21 '@angular/http': 'npm:@angular/http/bundles/http.umd.js', 22 '@angular/router': 'npm:@angular/router/bundles/router.umd.js', 23 '@angular/forms': 'npm:@angular/forms/bundles/forms.umd.js', 24 // other libraries 25 'rxjs': 'npm:rxjs', 26 'angular-in-memory-web-api': 'npm:angular-in-memory-web-api', 27 }, 28 // packages tells the System loader how to load when no filename and/or no extension 29 packages: { 30 app: { 31 main: './main.js', 32 defaultExtension: 'js' 33 }, 34 rxjs: { 35 defaultExtension: 'js' 36 }, 37 'angular-in-memory-web-api': { 38 main: './index.js', 39 defaultExtension: 'js' 40 } 41 } 42 }); 43 })(this);
3、按着「shift」鍵,右鍵項目文件夾,選擇「在此處打開命令窗口(W)」,鍵入DOS命令窗口,鍵入」npm install「,截圖以下:bootstrap
下載了好多文件,依賴的類庫可真多,以後的文件夾目錄以下:api
4、在根目錄下新建app文件夾,並依次建立下面三個文件app.module.ts、app.component.ts、main.ts;並在根目錄下新建html頁面——index.htmlangular2
1 import { NgModule } from '@angular/core'; 2 import { BrowserModule } from '@angular/platform-browser'; 3 import { AppComponent } from './app.component'; 4 @NgModule({ 5 imports: [ BrowserModule ], 6 declarations: [ AppComponent ], 7 bootstrap: [ AppComponent ] 8 }) 9 export class AppModule { }
1 import { Component } from '@angular/core'; 2 @Component({ 3 selector: 'my-app', 4 template: '<h1>My First Angular App</h1>' 5 }) 6 export class AppComponent { }
1 import { platformBrowserDynamic } from '@angular/platform-browser-dynamic'; 2 import { AppModule } from './app.module'; 3 const platform = platformBrowserDynamic(); 4 platform.bootstrapModule(AppModule);
1 <html> 2 <head> 3 <title>Angular QuickStart</title> 4 <meta charset="UTF-8"> 5 <meta name="viewport" content="width=device-width, initial-scale=1"> 6 <link rel="stylesheet" href="styles.css"> 7 <!-- 1. Load libraries --> 8 <!-- Polyfill(s) for older browsers --> 9 <script src="node_modules/core-js/client/shim.min.js"></script> 10 <script src="node_modules/zone.js/dist/zone.js"></script> 11 <script src="node_modules/reflect-metadata/Reflect.js"></script> 12 <script src="node_modules/systemjs/dist/system.src.js"></script> 13 <!-- 2. Configure SystemJS --> 14 <script src="systemjs.config.js"></script> 15 <script> 16 System.import('app').catch(function(err){ console.error(err); }); 17 </script> 18 </head> 19 <!-- 3. Display the application --> 20 <body> 21 <my-app>Loading...</my-app> 22 </body> 23 </html>
5、按照以下截圖,設定啓動做業:
設置成功以後,在啓動文件launch.json中作如上圖修改:${workspaceRoot}/node_modules/lite-server/bin/lite-server
6、在菜單欄中,點擊」查看「/」命令面板「或者快捷鍵」cltr+shift+p「,鍵入」configure「,選擇」任務:配置任務運行程序「,以後選擇」TypeScript-tsconfig.json 建立TypeScript項目「,以下圖:
按照教程博客所說,要task.json作如上圖修改,不然下面調試時若是出現錯誤沒有任何提示。
7、以上已經完成了全部的工做,開始調試。按下」ctrl+shift+b「,執行編譯,會將ts文件編譯爲js文件,以下圖:
若是編譯成功(如上圖),就能夠按」F5「了,以下圖:
可是若是編譯不成功,應該是沒有安裝tsc,使用命令」npm install -g typescript「安裝一下,以後再編譯就沒問題了,以下圖:
這裏徹底是按着上面的教程來的,有點很差意思,只做爲練習記錄,再次感謝!
