Answer 1

You could try to download the ruby enterprise deb package on the phusion site. And install passenger through the package. Follow the instructions here. Or you could try the bash script found here.

Answer 2

Just goto Ruby Source Package , Unzip it.

Goto /your-ruby-dir/ext/zlib

ruby extconf.rb
make
sudo make install

If the packages are missing it will tell you, mainly libzlib related packages

I really didn't like any of these answers ... none really focused on the users actual needs and question ... just people telling what they did ... no context and it didn't even work for me ...

So, ..

I'm installing a new box Ubuntu 8.04 LTS 64-bit ...

So, I ...

cd ~  
wget ftp://ftp.ruby-lang.org//pub/ruby/1.9/ruby-1.9.2-p180.tar.gz  
tar -xvvf ruby-1.9.2-p180.tar.gz  
cd ruby-*  
./configure  
make  
install  
sudo make install  

And then I have this problem with ...

gem list

it doesn't work ... something about zLib not found crap ...

So, I actually READ the README and find that I need to edit a file ...

[my ruby source directory]/ext/Setup

and UN-COMMENT the line with zLib in it ... by removing the "#" in the first column

Then I run the commands again ... included here for reference ...

./configure
make  
install  
sudo make install  

and all is well ... it's logical ... and is devoid of "rvm" and other ... "just install more stuff to make it work" type solutions.

Answer 4

yes, and that didn't do the job either. Got this from another source, this finally did it for me where the other stuff failed.

wget http://www.blue.sky.or.jp/atelier/ruby/ruby-zlib-0.6.0.tar.gz
tar xvzf ruby-zlib-0.6.0.tar.gz
cd ruby-zlib-0.6.0
ruby extconf.rb && make
sudo make install

Reinstall ruby gems from source

Thanks anyway, guys.

Answer 5

If you come across this question trying to install Ruby using Ruby Version Manager (RVM) on Ubuntu 10.04 then there are instructions on installing zlib on the rvm web site http://rvm.beginrescueend.com/packages/zlib/

The steps are:

rvm pkg install zlib

(or rvm package install zlib if you get "ERROR: Unrecognized command line argument: 'pkg'" - older versions of rvm used the verb 'package' instead)

then

rvm remove 1.9.1
rvm install 1.9.1

Answer 6

Did you try apt-get install libzlib-ruby?

Also install rubygems from rubyforge. I don't like the rubygems package in Ubuntu.
