Does yum install dependencies too?

Have this casual doubt? Tried installing ruby on centos using yum. I got the 1.8.5 as the release version. (This is not the latest release though). It showed only two things to download. I am doubtful if this is right? I did a yum deplist ruby it listed lots of things!!!

Maybe you had most of the dependencies already installed. Yum should manage them automagically.

Did you check if the dependencies weren't already installed on your system?
(rpm -q <packagename>, or rpm -qva | grep <packagename>)

De deplist option shows all dependencies but doesn't check if the're installed. The latter proces is done during the actual installation.

apt-get in ubuntu was much better

@timvandijk039: This is wht I did in my console just now:

Code:

[root@chat ~]# rpm -q ruby
ruby-1.8.5-5.el5_3.7
[root@chat ~]# rpm -qva | grep ruby
ruby-irb-1.8.5-5.el5_3.7
ruby-libs-1.8.5-5.el5_3.7
ruby-1.8.5-5.el5_3.7
[root@chat ~]#

That good, but what I ment was to check for the packages that ruby depends on. For example:

Code:

rpm -qva | grep ruby-libs

The Ruby package depends on various other packages. One of them for example is glibc. The glibc package can be found on many systems by default so you won't be bothered with that information. But it still is a dependency for the Ruby package.

Hope this helps.
