- 安裝Node.js npm
下載 node 最新版,安裝好后切換到淘寶鏡像源：
npm install -g cnpm --registry=http://registry.npm.taobao.org
npm install -g cnpm --registry=http://registry.npm.taobao.org
- 安裝Ionic2
cpm install -g ionic
需要注意的是，如果之前安裝過 Ionic 2 的 beta 版本，需要先卸載掉：
npm uninstall -g ionic
安裝完成后輸入以下命令看一下版本號(hào)：
ionic -version
2.1.0
目前最新版本是2.1.0。如果是 beta 版本的話，請(qǐng)重新安裝，確保安裝最新版。
3. 創(chuàng)建項(xiàng)目
打開 Node 命令行，首先 cd 到項(xiàng)目目錄，使用 start 命令來創(chuàng)建一個(gè)新App：
cd /d/javascript
ionic start MyIonic2Project tutorial --v2
語(yǔ)法:
ionic start 項(xiàng)目名稱 項(xiàng)目模板 版本項(xiàng)目名稱：自定義 項(xiàng)目名稱：[ tabs|tutorial|blank]，默認(rèn)會(huì)使用 tabs 模板 版本：--v2
參數(shù)必須要加，不然會(huì)建立 v1.x 版本的項(xiàng)目
如果失敗，有可能會(huì)出現(xiàn)以下信息：
Creating Ionic app in folder E:\Workspaces\Ionic2\MyIonic2Project based on tutorial project

Installing npm packages...
Error with start undefined
Error Initializing app: There was an error with the spawned command: npminstall
There was an error with the spawned command: npminstall
Caught exception:
undefined
Mind letting us know? https://github.com/driftyco/ionic-cli/issues
這說明 npm 安裝的時(shí)候失敗了，可以 cd 到項(xiàng)目目錄，使用之前設(shè)置過的 cnpm 命令：
cd MyIonic2Project
cnpm install
直到最后輸出類似以下信息：
√ All packages installed (477 packages installed from npm registry, used 2m, speed 77.14kB/s, json 549(3.42MB), tarball 3.38MB)
4. 在瀏覽器中運(yùn)行
ionic serve
輸出類似下面的內(nèi)容：
ionic serve
ionic-app-base@ ionic:serve D:\javascript\ionicFirst
ionic-app-scripts serve
keywords if/then/else require v5 option
[17:06:30] ionic-app-scripts 0.0.47

[17:06:53] watch ready in 22.08 s
[17:06:53] dev server running: http://localhost:8100/
接著瀏覽器會(huì)打開一個(gè)地址為 http://localhost:8100 的窗口，端口號(hào)根據(jù)當(dāng)前PC的實(shí)際情況可能會(huì)有變化，如果8100被占用了會(huì)使用8101等。
