CentOS: RVM and no package libyaml available

Question

I'm trying to install RVM on a CentOS host and it fails with this error:

/usr/local/rvm/rubies/ruby-1.9.3-p194/bin/ruby: error while loading shared libraries: libruby.so.1.9: cannot open shared object file: No such file or directory
Libraries missing for ruby-1.9.3-p194: libruby.so.1.9. Refer to your system manual for installing libraries
Mounting remote ruby failed, trying to compile.

After some Googling it seems I need to manually install the libyaml package, to which the host says:

No package libyaml available.

Any ideas?

Try installing this using RVM :

rvm pkg install libyaml

It works on my CENTOS 6.3 VPS.

This installs `libyaml`, but not `libyaml-devel`. For that, it still returns "No package libyaml-devel available" for the defautlt CentOS repos. – Thilo Apr 17 '13 at 09:21

with the latest rvm (run rvm get head), libyaml is automatically fetched when installing Ruby (well, at least on 1.9.3).

You'll see if it has been installed by inspecting /usr/local as that's where rvm puts it...

I've managed to solve it by piecing together others' attempts. I followed these instructions, and despite getting an error that read:

Error running 'autoreconf -is --force', please read /usr/local/rvm/log/ruby-1.9.2-p320/yaml/autoreconf.log

I managed to install both the rake gem and the rails gem.
