meteor 安装节点和NPM
示例
该快速入门是为MacOSXMavericks编写的，比其他安装说明更冗长。希望它可以涵盖一些边缘情况，例如设置路径和配置NPM，这可能会导致安装出现问题。
# install node
# as of OSX Mavericks, we need the GUI installer (?!)
# when a good command line alternative is found, we'll post it
http://nodejs.org/download/
# install npm
curl -0 -L https://npmjs.org/install.sh | sh
# check node is installed correctly
node --version
# check npm is installed correctly
npm -version
# find your npm path
which npm
# make sure npm is in your path
sudo nano ~/.profile
export PATH=$PATH:/usr/local/bin
