You need to install <code>zlib</code> before compiling/installing Ruby. If you didn't do this, make sure to remove everything related to Ruby 1.9.1 from your <code>~/.rvm</code> folder (so that it will be build from scratch).

Install <code>zlib</code> using your favorite package manager:

<pre><code>sudo apt-get install zlib1g-dev
</code></pre>

You might also want to install the following packages as they are required by tools like OpenSSL, 
Nokogiri, IRB or SQLite:

<pre><code> libssl-dev libreadline6-dev libxml2-dev libsqlite3-dev
</code></pre>

Then install Ruby 1.9.1 again (nowadays I would suggest to use a newer version):

<pre><code>rvm install 1.9.1
</code></pre>

Watch for "compiling ...". This should take a while. If it doesn't, then Ruby 1.9.1 might still be cached 
in your <code>~/.rvm</code> folder.

I encountered this problem when trying to:

<blockquote>
 gem install gruff
</blockquote>

What actually worked for me (Ubunut 10.10, ruby MRI 1.8.7) is:

<ul>
<li>reading the rvm notes and installing the dependencies for my ruby version</li>
</ul>

<blockquote>
 sudo apt-get install build-essential bison openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev autoconf
</blockquote>

<ul>
<li>then following closely the steps described in <a href="https://rvm.io/packages/zlib/" rel="nofollow">https://rvm.io/packages/zlib/</a> </li>
</ul>

<blockquote>
 <ol>
 <li>rvm package install zlib</li>
 <li>rvm remove 1.8.7</li>
 <li>rvm install 1.8.7</li>
 </ol>
</blockquote>

So basically: just follow the rvm manual

blocks|key|3269749|text|另外，你也知道1.9.1是非常糟糕的，这就是为什么没有人认真使用它的原因，对吧？这对所提出的问题的重要性在于，许多人没有意识到这一点，并试图将其与Ruby+On+Rails等API一起使用。然而，正如rubyonrails.org/download声明的那样，Ruby+1.9.1不支持与Rails一起使用，因为它已经损坏。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3269750|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

Also, you do know that 1.9.1 is horribly broken which is why no one uses it seriously, right? The importance this has to the question asked is that many people do not realize this and attempt to use it with such APIs as Ruby On Rails. However, as rubyonrails.org/download states, Ruby 1.9.1 is not supported for use with Rails as it is broken.

On the latest Ubuntu (11.10) there is also an issue with readline.

<blockquote>
 Readline was unable to be required, if you need completion or history
 install readline then reinstall ruby.

So my entire rvm and latest ruby install process for ubunutu 11.10 was:

<pre><code># install rvm
sudo apt-get install curl
curl -L get.rvm.io | bash -s stable

# install dependencies
rvm pkg install zlib
rvm pkg install readline

# install additional dependencies -- follow instructions for your distribution/version
rvm requirements

# install ruby
rvm install [ruby-version]
</code></pre>

I'm posting this for my future reference and in case anyone else bumps into this issue as well.

blocks|key|314566|text|对我来说，解决方案非常简单:我忘记了关闭/重新打开shell，就像rvm安装程序告诉我的那样。在我这样做之后，zlib错误就消失了，我能够:+gem+install+bundler|type|unstyled|depth|inlineStyleRanges|entityRanges|data|314567|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

For me, the solution was very simple: I had forgotten to close/reopen the shell, as rvm setup had instructed me to do.
After I did that, the zlib error was gone and I was able to: gem install bundler

Trying to get Ruby 1.9.1 up and running with RVM on a fresh install (fedora). 

After doing <code>rvm install 1.9.1</code>, the rubygems error logs show that zlib can't be located

</blockquote>

However both the zlib runtime and development libraries are installed and up-to-date. 

I'm kinda stumped on this one at the moment.
