How to get list of dependencies of non-installed RPM package?

Question

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?

Solution 1

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>

Solution 2

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.

Solution 3

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

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

Solution 4

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

Solution 5

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 :-)

How would I do the same if I have a local rpm file?

[Vi.]

Maybe extract the control file from rpm package and look into it?

[Ignacio Vazquez-Abrams]

If you have it downloaded then you use rpm -qp --requires <package file>.

[deesto]

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.

[Asclepius]

Works for URLs too.

[natxo asenjo]

if you ommit -q then you can query your configured repos: rpm -qR graphviz lists all the dependencies for me

[nlu]

If you use RHN, you need to add --plugins to the call to repoquery. See stackoverflow.com/questions/15433843/…

[haridsv]

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).

I don't think it's true that yum can't do this. See the answer below
