Install bundler with rbenv/ruby-build

Question

I've installed rbenv and downloaded a ruby using ruby-build, e.g.

rbenv global 1.9.3-p448
gem env # This show my customized ruby gem paths instead the system one, 
        # so it works!

Then I install bundler,

# gem install --no-ri --no-rdoc bundler

ERROR:  Loading command: install (LoadError)

    cannot load such file -- zlib

ERROR:  While executing gem ... (NameError)

    uninitialized constant Gem::Commands::InstallCommand

If I don't use rbenv and use my system ruby, I can install bundler. but how to install when I am using rbenv?

What is the output of `which ruby` and `which gem` when rbenv ruby selected? Did you do `rbenv rehash` after installing ruby with ruby-build? — Yuri Golobokov, Jun 13 '14 at 12:22

Maybe related to this similar question with RVM

Try installing zlib first :

APT :

sudo apt-get install zlib1g-dev

YUM :

sudo yum install zlib-devel

Then reinstall ruby

I had a same problem when I was using lodash-rails with Rails,

This is an usual problem when you have standalone ruby along with rbenv OR RVM OR any version managers , Its always good and stable to remove all ruby installations in your system and use only rbenv OR RVM as your ruby platform .

People use rbenv or RVM so that they can switch between any ruby version as per the requirement .

Possible reason for your problem : -

I think bundler is trying to install some dependency and that particular dependency is referring to system env path which set in your

.bashrc     OR 
.bash_profile     OR 
.profile file

normally bundler checks for gem path which might have been set in any of your bash profile files .

set that gem path to your .rbenv/version/versionnumber/gems folder .

in your home directory . Check in the above listed files and see if you have any ruby references , if so remove just remove them .

I have a bash script that makes ruby/rails install easy on debian/ubuntu. It also installs many dependencies that you might need.

You can find it here: https://github.com/yoones/railsondeb

If you encounter any problem, don't hesitate to let me know (an issue will do).
