【node.js】update

一。用n模块更新

1.首先安装n模块：

npm install -g n

2.升级node.js到最新稳定版

n stable

n后面也可以跟随版本号比如：

n v0.10.26或n 0.10.26

➜  test git:(master) ✗ npm install -g n
/usr/local/bin/n -> /usr/local/lib/node_modules/n/bin/n
n@2.1.0 /usr/local/lib/node_modules/n
➜  test git:(master) ✗ n stable
mkdir: /usr/local/n/versions/node: Permission denied
mkdir: /usr/local/n/versions/io: Permission denied

     install : node-v5.2.0
       mkdir : /usr/local/n/versions/node/5.2.0
mkdir: /usr/local/n/versions/node/5.2.0: Permission denied

  Error: sudo required

➜  test git:(master) ✗ node -v
v0.12.4
➜  test git:(master) ✗ sudo n stable
