EPEL is self-reliant. Nothing in EPEL will depend on another other than
Base/Updates. You need to check which repo you're installing the package
from, and be careful with the package name itself. There shouldn't be
duplicate names.

In your example, the nodejs package is coming from SCL, so you would
need to use the scl tools to enable that utility (which then
appropriately updates your user's environment)

For example, 'scl enable nodejs010 bash' would give you a bash shell
with the appropriate environment for using the nodejs from SCL.
