apt-cache show <package> shows also it's dependencies.

yum info <package> does not show dependencies, but it obviously know them.

How to ask yum for dependencies of specified package?

81

yum doesn't have that capability. Use the repoquery tool from the yum-utils package instead.

repoquery --requires <package>

OR to also see which additional RPM packages are needed to satisfy the dependencies, use --resolve

repoquery --requires --resolve <package>
  • How would I do the same if I have a local rpm file? – Usman Ismail Apr 23 '12 at 15:38
  • Maybe extract the control file from rpm package and look into it? – Vi. Nov 26 '12 at 10:56

    If you have it downloaded then you use rpm -qp --requires <package file>. – Ignacio Vazquez-Abrams Nov 26 '12 at 12:27
  • If you use RHN, you need to add --plugins to the call to repoquery. See stackoverflow.com/questions/15433843/… – nlu Dec 21 '16 at 11:39
  • What does --resolve actually do? Running repoquery --requires --resolve on a package that is already installed should return an empty list right, since all dependencies are already satisfied? When I tried it on a package that is already installed, I got a few listed, including itself (all of these are already installed). – haridsv Dec 7 '18 at 9:25

Use deplist command,

yum deplist <package>

From yum's manual:

Produces a list of all dependencies and what packages provide those dependencies for the given packages.

Update for dnf

To do the same thing with dnf, we can do

dnf repoquery --requires <package>

As man yum2dnf said:

Alternative to Yum deplist command to find out dependencies of the package is dnf repoquery --requires using repoquery plugin.

    Unfortunately, this will return a list of all possible providers of each dependency, which can end up returning many hundreds or thousands of lines, instead of a simple list of the names of dependent packages. – deesto Aug 8 '13 at 20:00

If you have a local RPM, you can get a list of dependencies via:

rpm -qpR mediawiki-1.4rc1-4.i586.rpm

    Works for URLs too. – A-B-B Aug 27 '14 at 22:19
  • if you ommit -q then you can query your configured repos: rpm -qR graphviz lists all the dependencies for me – natxo asenjo May 4 '15 at 13:12

If you need the list of packages needed, use:

dnf repoquery --requires --resolve`

In the case of firefox, by running:

sudo dnf repoquery --requires --resolve firefox

If you want to install a package and it's dependencies via yum, try the localinstall option instead if install. The localinstall install a package and finds any dependencies and downloads them:

$ yum -y localinstall <package>

I am no yum guru but this works fine for me, makes it easy to install including dependencies :-)
