Install Ruby 1.9.3 with libyaml on CentOS
Ruby 1.9.3-p0 makes psych—the replacement for 1.8.7’s YAML library, Syck—the default YAML parser. Psych is a wrapper around libyaml, so you’re going to need it installed and configured before installing Ruby.
If you install 1.9.3-p0 without libyaml, you’ll see warnings like this:
It seems your ruby installation is missing psych (for YAML output).
To eliminate this warning, please install libyaml and reinstall your ruby.
Installing libyaml
$ wget http://pyyaml.org/download/libyaml/yaml-0.1.4.tar.gz
$ tar xzvf yaml-0.1.4.tar.gz
$ cd yaml-0.1.4
$ ./configure --prefix=/usr/local
$ make
$ make install
Quick review of what’s going on: download and untar the source code, change to the directory and install the package. You may need to sudo the make install command. Your mileage may vary.
Installing Ruby 1.9.3-p0
$ wget http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p0.tar.gz
$ tar xzvf ruby-1.9.3-p0.tar.gz
$ cd ruby-1.9.3-p0
$ ./configure --prefix=/usr/local --enable-shared --disable-install-doc --with-opt-dir=/usr/local/lib
$ make
$ make install
After installing, you can verify that Ruby was installed with ruby -v. It’s also worth trying gem --version to make sure you don’t get any errors regarding psych.
I tried installing libyaml-devel and libyaml from Yum, but couldn’t get ruby installed and recognizing those packages. Out of frustration, I turned to installing libyaml by source and it Just Worked™.

If you don’t want to compile manually rbenv (with ruby-build) takes care of installing libyaml for you too
just a quick note, rvm will install libyaml for you too :)
Haris Amin* & *shapeshed: Great points! I should have pointed out this was for a server which isn’t using rvm or rbenv.Yup, rvm 1.9.2 installs it https://gist.github.com/1329273#gistcomment-60100
You should be able to get installed libyaml from EPEL packages [1]. Also, you should be able to build RPM packages for R1.9.3 from my spec file [2].

I get error running ‘make’ and error running ‘make install’ when I use rvm install 1.9.3
I cannot read the log since I do not understand it, but it is a log tied to the yaml-0.1.4 folder.
I would like to use RVM since I want to make gemsets and being a newbie it gives me some security …lol
Any suggestions on how I can let RVM know that ruby 1.9.3 is installed if I install from source using the above.
Thanks,
Tom.
@Tom: If you’re using RVM you won’t need to install libyaml from source. RVM will take care of that for you.
To install Ruby 1.9.3-p0 via RVM run
rvm install 1.9.3-p0Hi Brian,
Thanks for your reply to my earlier posting with respect to RVM install 1.93 and the subsequent errors as it tried to install yaml.
That was the problem …. RVM tried to install Yaml 0.1.4 and in the process it gave me two warnings, one after the other and subsequently it did not install Ruby 1.9.3 even though it indicated that the installation was complete.
The two warnings were, first “error running ‘make’” and the second was “error running ‘make install’”
Maybe it is something about my setup …. I have just downloaded Ubuntu 11.10 for windows and I installed GIT and then RVM and they both worked just fine then I thought I would use RVM to install Ruby 1.9.3.
I removed Ubuntu and now I am about to start all over … any other thoughts on this …. I know each installation is so different … but maybe you see a work around.
Thanks again,
Tom.

Hey Brian,
I found a temporary work-around, that is for some folks it worked, unfortunately for me it did not.
But if you are interested here is the link:

Great - thanks the libyaml build install worked for me - and fixed the same problem you described with the 1.9.3 install.
Hi! i’m repost you post: to my @urciibqo twitter
For Debian Lenny, first add to /etc/sudoers:
your_user ALL=NOPASSWD:/usr/bin/make
Thany you! Gerald
Correction.
Sorry - it should bei Debian 6 - Squeeze.
Best regards
Gerald
Thanks for the useful tip. I found that instead of
–with-opt-dir=/usr/local/lib
I need to run ./configure with
–with-opt-dir=/usr/local
(without the lib). Otherwise, strace shows the loader trying to load the libyaml library from /usr/local/lib/lib.
thanks for your article this helpfull with me
best regards
Why 1.9.3 is not yet recognize by rvm. Any ideas?
Thank you. After wasting time with apt yaml, I got here. Installing from source works great. Thanks.
Great tutorial, after a DAY trying to figure out how to install Ruby via other tutorials, this one was straight forward and easy to follow… you’re a life saver!!! TY!!! By the way could you also post a video for this?
I have installed libyaml and libyaml-devel from yum(EPEL on CentOS 5) and I run:
./configure –with-opt-dir=/usr/include/
Them, make and make install.
It works!
Thanks!
I was hitting my head against the wall until I tried Ruby 1.9.3-p0 not the latest Ruby 1.9.3-p125.
Thanks!
I got this working by changing the ruby configure line to:
./configure –prefix=/usr/local –enable-shared –disable-install-doc –with-opt-dir=/usr/local
This picks up the library and the include file itself, which is apparently important, now.
Thanks dude
Thanks Ryan, this worked great for me.
Thanks bro ..! it works
Followed it to a T, no errors, but when I check version it’s still at 1.8.5. :/
Hello
I had the same problem on openSUSE. After some searching, I found a blog post (http://blog.sethladd.com/2007/03/installing-openssl-support-for-ruby-on.html) that pointed me in the right direction. By following those instructions, I was able to install psych (and other stuff) with the libyaml available through my package manager.
I don’t know how/if the openSUSE packaged version differs from CentOS and whether or not this would work for other uses, but hopefully it helps someone!
Forrest, hopefully you solved this, but your PATH probably has /usr/bin ahead of /usr/local/bin, which is where these directions put the updated ruby. That’s what happened to me at least.
Thanks! This worked beautifully for me.
how can i test if the libyaml is installed correctly?
i have problems with the installation of libyaml and i think that it is the problem causes problems in my cpanel ( i can’t install ruby aplications with this error: “An unknown error was encountered when creating your rails application. “).
Thanks . I got it at the version of ruby 1.93p134 on CentOS5.8
Brian, you have no idea how much time (and money) you have just saved me.
I was about to give up and outsource the install, usually I am able to do this sort of thing myself, however after 3 hours of trying to figure out the Linux commands, I was ready to throw in the towel.Then, I stumbled upon this article. Thanks very much!
I´ve tried to complete the requierements of yeoman for almost 4 hours, most of the time was gone trying to successfully upgrade ruby. Thanks.
https://github.com/sstephenson/ruby-build/issues/119 check it out it worked for me and my comments are below - on Centos 6.3
Thanks, worked a treat!
thank you, man, it helped!
I was looking around on google, but could not find any satisfy answer, but your tips works great !!
Thanks :)
Hey, I made a gist out of this for anyone to use. Check it out here:
https://gist.github.com/4337899
I updated the ruby version to the latest, ruby 1.9.3-p327. Now you can just run: ‘curl -L https://gist.github.com/raw/4337899/82702babb65ab72b6b8dec63b5346ca3c6f32e65/ruby_1.9.3-p327_install.sh | bash’ and it’ll just work.
;)
Thank you for your help with this…
I also had to leave off /lib from –with-opt-dir=$HOME
This worked great a couple of months ago. Now, since I have 1.9.3-p0 installed: how do I update the ruby to 1.9.3-p392 ? Do I just follow the same ruby install steps above but replace with the p392 url? Will it overwrite the p0 ruby or do I have to uninstall p0 first and then install p392? Do I have to reinstall all gems again? Thanks.
Thanks for sharing, as adding libyaml via apitude on Ubuntu didn’t worked for me
Thanks a lot!!
If you installed libyaml and libyaml-dev via yum, you need –with-opt-dir=/usr.

Please suggest what needs to be done for installing ruby
Makes sense to me.
