npm should be run outside of the node repl, in your normal shell

Node版本：v0.12.4

在安装 npm install -g -supervisor是出现：

npm ERR! addLocal Could not install D:\Program Files\nodejs
npm ERR! Windows_NT 6.3.9600
npm ERR! argv "D:\\Program Files\\nodejs\\\\node.exe" "D:\\Program Files\\
\\node_modules\\npm\\bin\\npm-cli.js" "install" "-g" "-supervisor"
npm ERR! node v0.12.4
npm ERR! npm v2.10.1
npm ERR! code EISDIR
npm ERR! errno -4068

npm ERR! EISDIR, read

npm ERR! Please include the following file with any support request:

也就是说，想要运行node命令，需要在系统的shell中，比如windows的cmd。node自带的那个叫repl，不能在其中运行npm命令，只能运行js语句

需要在其它的CMD文件命令行下运行

npm install -g supervisor即可；
