It looks like your rubygems source is corrupted.
Assuming you really need to use ubuntu packages, try purging the
package and re install it.

However, if you can use something like RVM[1] or rbenv[2] to install
and manage ruby.

Hope this helps.

Cheers.

I think this is what you need...
apt-get install zlib1g-dev

but if that doesn't work, then try this...
apt-get install libzlcore-dev

If you installed rubygems it would seem impossible for the command
update_rubygems not to be found. Perhaps it is not installed.

Perhaps someone is familiar with Ubuntu's ruby packages and can guide
you with what it is that isn't working right. Generally, the
distribution packages lag too far behind and seem to be an obstruction
which is one of the reasons why things like rvm have become popular.

I suppose the way to install it would be...
sudo apt-get install rubygems

On my ubuntu 10.04 LTS (but not using any Ubuntu ruby packages
whatsoever because I use the enterprise ruby packages)

If rubygems package is installed, you should be able to easily run 'sudo
update rubygems'

I strongly suggest that for rails on Ubuntu you use the method from
http://ryanbigg.com/2010/12/ubuntu-ruby-rvm-rails-and-you/
as an earlier poster already suggested. You are in for a great deal
of pain trying to do it using the ubuntu repositories.

thank Colin..
i already try this suggestion before but still not working and i cannot
install sinatra and thin using this method.

hi Craig.. i can execute sudo gem update_rubygems after i uninstall rack

i hope somebody can help me with this kind of problem..

[mkristian]

I use $HOME/.gemrc

install: --user-install --no-ri --no-rdoc --bindir /home/kristian/bin
update: --user-install --no-ri --no-rdoc --bindir /home/kristian/bin

which installs all gems in my user directory - no sudo needed. BUT
bundler does not obey this setting and ask for sudo password and
installs them into the system.

I think the easiest way to get rubygems and bundle working "locally"
is setting something like

export GEM_HOME=$HOME/.gems
export GEM_PATH=$HOME/.gems

then rubygems and bundler works fine together.

I just tried this on ubuntu 11.10 where I do have
$ gem envir

and there is no problem to install sinatra and thin. from that thread
I conclude you do not have the right version of rubygems installed try
to install the version from 11.10

I can only suggest once that again that you start from the beginning
using rvm (if you have installed rubygems from the repository then
uninstall it and manually install an appropriate version) and when you
come to a problem come back and ask about that particular problem.
When I suggested previously that you did this you just said "i already

try this suggestion before but still not working and i cannot install

sinatra and thin using this method." which is not very specific.

This may not fix the problem but once you are using rvm you will be
better aligned with most people here (I believe) and will therefore be
more likely to find a solution.

I also produced an even more detailed Ruby on Rails installation
tutorial for Ubuntu 11.04, 11.10:
http://www.mirceagoia.com/2011/11/ruby-on-rails-installation-ubuntu-linux-mint/
It's 35 pages long and free to get it. Covers many situation which
Ryan Bigg didn't.

rubygems manualy and extract to .rvm/src. then install rvm 1.9.2
again.the rubygems install successfull but when i test gem by trying to
install rails the same error display.i also try the zlib troubleshooting
on part8 provide by
http://www.mirceagoia.com/2011/11/ruby-on-rails-installation-ubuntu-linux-mint/
tutorial but it still not working.below is all the output.

I don't know if this effects you or not, but if you're behind OpenDNS
then you're likely having issues because of them. I had this issue
myself just today (which is how I stumbled on this forum post) and the
resolution for me was to add the following to my hosts file:

205.251.203.201 production.cf.rubygems.org

if you go to production.cf.rubygems.org in your web browser, and this is
your issue, you'll get an OpenDNS message which essentially claims
production.cf.rubygems.org distributes malware/viruses. Adding the hosts
file entry allowed me to bypass opendns entirely for the one site. This
is only a temporary fix, though. I've sent mail to the email address in
the OpenDNS error page for production.cf.rubygems.org and it would be a
good idea if anyone else affected by this did the same so that the root
cause can be taken care of.

thank you very much Damian M.
but my problem is different,however
your reply really point me to the solution.

[Bob B.]

Awesome that DNS fix in etc/hosts worked for me

Finally ..
$ sudo gem install rails
Fetching: i18n-0.6.0.gem (100%)
Fetching: multi_json-1.0.4.gem (100%)
..

Many thanks Damian!!

Excuse, how did you solve the question? I meet the same question today..

[wu volity]

I need your help,Please..What is the meanning of '205.251.203.201' in
'205.251.203.201 production.cf.rubygems.org'.

It is an ip address. At one time it may have been (or may still be,
but I suspect not) a valid ip address for production.cf.rubygems.org.
But since the email you got this from is two years old it may no
longer be valid.

Perhaps if you explained what your actual problem is (preferably in a
new thread rather than an ancient one) someone may be able to help.

Thanks!

I believe that's a production IP for CloudFront so it should in theory
be valid for RubyGems still but that line as it's printed in the
quotes look like a hosts file line, perhaps somebody trying to stick
the region?
