I've added the EPEL repository and attempted to install npm (since it is not included in the standard repos), but get the following error:
Error: Package: nodejs-devel-0.10.33-1.el7.x86_64 (epel) Requires: c-ares-devel(x86-64) No package c-ares-devel available. when I try to install that.
Adding RPMForge repo does not help.
yum --skip-broken install npm just skips the npm package.
The c-ares package is installed but does not seem to meet the c-ares-devel dependency.
