CentOS 6.5安裝Node.js, npm

CentOS上能夠經過下載*.tar.gz安裝包的方式本身解壓縮、編譯的方式安裝，同時還能夠採用EPEL的方式安裝：

Node.js and npm are available from the Fedora Extra Packages for Enterprise Linux (EPEL) repository. If you haven't already done so, firstenable EPEL.

To check if you have EPEL, run

yum repolist

if you don't see epel, install it via RPM (At the time of this writing, the last version is 6.8.)

rpm -Uvh http://download-i2.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm

And then run the following command to install node and npm:

sudo yum install nodejs npm --enablerepo=epel

or if this doesn't work for you install node separately:

sudo yum install npm --enablerepo=epel
