Puppet users - May 2009 - "Could not prefetch package provider 'yum': Command rpm is missing"

I have just installed Puppet on CentOS.  One of about 15 machines in
our organization.  Currently 5 have puppet installled, all CentOS.

On this particular machine, Puppet fails to run most of our recipes,
stating:

''Could not prefetch package provider ''yum'': Command
rpm is missing''

I''ve not had any issues with our other machines, and I can manually
run yum and rpm on the command line, without issue.

I''ve tried to look through the code for the providers/packages/*.rb,
but I''m not a Ruby super-star, and it doesn''t make sense.

Could someone shed some light on why Puppet might have trouble finding
''rpm'', and how I could further troubleshoot, and ultimately
fix this
problem?


Thanks,

Kyle Mallory

What version of puppet?  also what is your path set to.  I had a  
problem on an older version of puppet (can''t remember which one)  
where i had ''/etc'' on my path and puppet was trying to use
/etc/rpm
as the rpm command, but /etc/rpm is a directory and then failed.

It has been fixed in the more current versions (I''m currently running  
0.24.8 on my centos systems).

Thanks Jim,

Digging in, trying to get versions and paths, and all that stuff to
answer your questions, I found that my problem machine didn''t have
''which'' installed.  Apparently puppet relies on it to resolve
the
path.  Once I installed it, puppet ran fine.

Thanks again.

Kyle

FWIW, installing the puppet packages from EPEL¹ would (or certainly
should) have avoided this issue, as puppet requires facter and facter
requires which.  How did you install puppet?

(It is arguable that puppet should require which directly as well,
just to future proof against a time when facter no longer requires
which.  But that seems far fetched.  If facter is taught to do without
which, puppet probably would be by then as well.)

Puppet (and Facter) was installed by hand (I have a script to install
the latest from reductivelabs.com).  I wasn''t aware of EPEL, or that
it maintained a puppet package.  I''ve forwarded this on to our
internal repo manager to see if this is something that we can include
in our local mirrors.  This is certainly welcome news.

I thought it was strange the puppet required ''which'', and
didn''t have
a fall-back mechanism to just try executing the command directly, or
manually parsing the environment path to see if it existed there.
