《ionic2常见问题汇总之安装篇》

如何安装ionic？

## 系统包管理器，安装npm
apt-get install npm nodejs

## 修正nodejs快捷方式
ln -s /usr/bin/nodejs /usr/bin/node

## 更换国内软件源
npm -g install nrm

nrm ls

nrm use taobao

npm install -g npm@3.8.0

## Nodejs包管理器，安装ionic
npm -g install cordova

npm -g install ionic@beta

ionic@beta安装Error无法运行怎么解决？

windows 解决方案

npm install -g npm@3.8.0

npm cache clean

npm install -g cordova

npm install -g ionic@beta

debian 解决方案

npm install -g npm@3.8.0

npm cache clean

npm install -g cnpm --registry=http://registry.npm.taobao.org

cnpm install -g cordova

cnpm install -g ionic@beta

安装提示root用户没有权限访问node-pre-gyp？

sudo cnpm -g install ionic@2.0.0-beta.20 --unsafe-perm

如何生成第一个ionic项目？

## 生成ionic1项目
ionic start project-name

## （可尝试）生成ionic2项目
ionic start project-name --v2

## 运行测试项目
cd project-name
ionic serve -l

生成ionic@beta.23项目报错

Installing npm packages...

Unable to run spawn commandError: spawn npm ENOENT (CLI v2.0.0-beta.23)

回滚至 beta 22版本即可

I have the exact same issue. Worked in beta 22.

Reverting to the earlier beta resolved the issue:

npm -g install ionic@2.0.0-beta.22

生成ionic@beta项目报错

npm install package Error

进入项目执行npm包安装命令

cd project-name

cnpm install

无法在真机运行 ionic run android

原因分析：

cordova@5.0.0版本过低，需要升级

npm -g install cordova
ionic platform add android
ionic run
cordova run android

gulp3中graceful-fs版本过低

错误信息

(node:2396) fs: re-evaluating native module sources is not supported. If you are using the graceful-fs module, please update it to a more recent version.
[1]    2396 bus error (core dumped)  gulp

I believe you need to downgrade your node version as Node SASS is not currently up-to-date with Node v6

需要将node降级到 v5版本

npm install -g n
n 5.12.0
