While installing, some errors are displayed. The command I am using is:
sudo gem install rails --include-dependencies
or
sudo gem install rails --no-rdoc --no-ri
In both cases, it is the same error. I think my rubygems may not be installed properly?
ERROR: Loading command: install (LoadError) no such file to load -- zlib ERROR: While executing gem ... (NameError) uninitialized constant Gem::Commands::InstallCommand
I have installed ruby-1.9.2-p0 and rubygems-1.3.7
One more thing: Do I have to cd into the ruby or rubygems directory and then install rails or can I do it from default directory?
Open command prompt and please let us know the results
verify Ruby version
ruby -v
verify gem version
gem -v
Use command
gem install rails
verify the rails version
rails -v
$ sudo apt-get install ruby1.9 gem1.9
checkout below mentioned link that would help you to install rails3 using rvm on ubuntu box
http://www.jaikeerthi.in/2010/11/install-rails-ubuntu/
You have to install zlib1g and zlib1g-dev
sudo aptitude install zlib1g zlib1g-dev
Some GEMs compile some binaries at installation time and need other libraries (such as zlib) be installed on the system.
Assuming that you are installing on Ubuntu 14.04...
First install rbev to pick a Ruby version for your application.
sudo apt-get update
Install the rbenv and Ruby dependencies with apt-get:
sudo apt-get install git-core curl zlib1g-dev build-essential libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev python-software-properties libffi-dev
Now let's install rbenv
cd
git clone git://github.com/sstephenson/rbenv.git .rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
git clone git://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bash_profile
source ~/.bash_profile
And now let's install Ruby:
rbenv install -v 2.2.3
rbenv global 2.2.3
Verify that Ruby is installed with this command:
ruby -v
Install bundler to manage gems:
gem install bundler
Now we are set to install Rails:
gem install rails
Then run
rbenv rehash
It's good to verify if the Rails is installed properly:
rails -v
Make sure to install database and Javascript runtime afterwards...

I am trying to install Ruby on Rails on my local machine for development purposes, but I have hit upon an error. I can't quite tell, but it seems like it might be a gem error. Though, this is my first time trying to use all three, Ruby, Gem and Rails, so I'm not sure.
Running the command "sudo gem install rails -V" these are the last few lines printed after the error is hit:
Building native extensions. This could take a while...

sudo apt-get install git-core

rvm install ruby-2.0
curl -L https://get.rvm.io | bash -s stable --rails
and it works fine. This will (currently) install Ruby 2.0 and rails 4.0 however.
I am very new to Linux (been living in MS world for many years). I thought I'd try something different, like ruby on rails under linux. Been trying to get a dev machine set up, and I must say, it's been quite overwhelming! Here is what I have done so far, and my current problem that I cannot figure out:
Installed Linux Mint 15 (was this a bad choice? the only reason I ask is all the difficulties I've had so far)
Ran the update manager and installed all updates.
Install git
sudo apt-get install git
Install rbenv
git clone https://github.com/sstephenson/rbenv.git ~/.rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
Install ruby-build as a rbenv plugin
git clone https://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
Install opensssl (the ruby install fails if I don't do this)
sudo apt-get install libssl-dev
Install ruby
rbenv install 2.0.0-p247
Set my ruby version
rbenv global 2.0.0-p247
Install rails
gem install rails
This fails with
Fetching: i18n-0.6.5.gem (100%)

ERROR: While executing gem ... (OpenSSL::SSL::SSLError)

So apparently, there's still something not quite right with the ssl lib? Either that or I've taken a wrong step somewhere? Please help, thanks!
I am pretty new in linux world.
I was having exactly the same problem after following the same steps.
In my case it got solve just doing:
gem update --system
After that the rails installation gave me no prob.
Hope is just that!
I'm running rails 4 with ruby 2.0 on Linux Mint 15.
I did:
sudo apt-get install git
sudo apt-get install curl

sudo apt-get install git-core
source ~/.rvm/scripts/rvm
bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts /rvm-installer)

rvm install ruby-2.0
curl -L https://get.rvm.io | bash -s stable --rails
and it worked for me. Maybe this helps
I am using osx 10.8.2 installed ruby 2.0 and....
got this when trying to run "sudo gem install rails"
$ sudo gem install rails
ERROR: Loading command: install (LoadError)

I had ruby 1.9.x and rails 3.2.x working alright before
You have to install OpenSSL first and recompile ruby again:
RVM:
rvm pkg install openssl
rvm reinstall ruby-2.0.0-p0 --with-gcc=gcc-4.7 --with-openssl-dir=$rvm_path/usr
If you're using RVM please follow:
$ brew install automake
$ rvm pkg install openssl
$ rvm requirements run
$ rvm reinstall all --force
$ gem install rails
It worked for me.
I had very bad time with this ERROR.
Finally i done with it. There is only Once solution either you are with RVM or without RVM.
Make sure you have installed OpenSSL first BEFORE installing ruby.
RVM
Uninstall rvm
rvm implode
or
rm -rf ~/.rvm
Don’t forget to remove the script calls in your .bashrc and/or .bash_profile (or whatever shell you’re using).
sudo apt-get install zlib1g zlib1g-dev build-essential openssl libssl-dev libmysqlclient18 libmysqlclient-dev libyaml-dev curl git-core python-software-properties libpq-dev nodejs
Then install RVM, post ruby.
OR
rvm pkg install openssl
rvm reinstall ruby-2.0.0-p0 --with-gcc=gcc-4.7 --with-openssl-dir=$rvm_path/usr
WITHOUT RVM
First you should find where Ruby is:
whereis ruby
will list all the places where it exists on your system, then you can remove all them explicitly. Or you can use something like this:
rm -rf /usr/local/lib/ruby
rm -rf /usr/lib/ruby
rm -f /usr/local/bin/ruby
rm -f /usr/bin/ruby
rm -f /usr/local/bin/irb
rm -f /usr/bin/irb
rm -f /usr/local/bin/gem
rm -f /usr/bin/gem
THEN
sudo apt-get install zlib1g zlib1g-dev build-essential openssl libssl-dev libmysqlclient18 libmysqlclient-dev libyaml-dev curl git-core python-software-properties libpq-dev nodejs
apt-get -y update
apt-get -y install build-essential zlib1g-dev libssl-dev libreadline6-dev libyaml-dev
cd /tmp
wget http://cache.ruby-lang.org/pub/ruby/2.0/ruby-2.0.0-p247.tar.gz
tar -xvzf ruby-2.0.0-p247.tar.gz
cd ruby-2.0.0-p247/
./configure --prefix=/usr/local
make
make install
I hope this help you.
I fix this error for ruby 2.1.2 as follow.
rvm pkg install openssl
rvm reinstall ruby-2.1.2 --with-openssl-dir=$rvm_path/usr
On OSX, with rbenv and homebrew, the following worked for me:
brew install openssl
CONFIGURE_OPTS=--with-openssl-dir=$(brew --prefix openssl) rbenv install whatever-ruby-version
This worked for me which is similar to some of the other answers already posted.
rvm pkg install openssl
rvm reinstall all --force
When installing ruby 2.0, it is possible that rubygems 2.0 installation did not complete ok, because of openssl.
Make sure you provide a valid path to the openssl config file; you could:
find . -type f -name "openssl.cnf"
path is usually $HOME/.rvm/usr or $HOME/.rvm/usr/ssl
Then
[sudo] rvm reinstall ruby-2.0.0-p0 --with-openssl-dir=[openssl.cnf path] --verify-downloads 1
Make sure rubygems installation complete successfully.
Might be a better way to fix that path without reinstalling, but this should do it.
Make sure to check out this page on the rvm site: https://rvm.io/packages/openssl/
Running
rvm requirements run
gave me:
Missing required packages: autoconf, automake, libtool, pkg-config, apple-gcc42, readline, libxml2, libxslt, libksba, openssl, sqlite
after brew install autoconf automake ...
I was able to rvm reinstall 2.0.0 without openssl errors
I had the same problem with the same OS version. I use rvm and followed the steps in this command:
$ rvm requirements
Following those instructions, I ran:
$ brew update
$ brew tap homebrew/dupes
$ brew install bash curl git
$ brew install autoconf automake apple-gcc42 libtool pkg-config openssl readline libyaml sqlite libxml2 libxslt libksba
I had the same problem earlier, tried all of the snippets about and none of them worked out. After looking around for a bit the following worked for me:
$ rvm remove 2.0.0 # get rid of unsuccessful installation
$ rvm get head --autolibs=3 # get the latest RVM and build required libs
$ rvm requirements # just in case, install all other required stuff
$ rvm install ruby-2.0.0
$ rvm --default use ruby-2.0.0
What does rvm get head --autolibs=3 do exactly? I'm guess it automatically downloads dependencies, but I was hoping for a clear answer.
I encountered the same openssl error on Fedora when trying to use gem install <package>. It seems you need to install additional packages with yum/dnf
sudo dnf install rubygems rubygem-bundler ruby-devel mariadb-devel
After running the above command, gem install <package> should now work.
just went through the same problem. Takes a bit time but, upgrading openssl with
brew upgrade openssl#1.1
worked for me. Version might be different in the future, type brew install openssl to see which version you can upgrade to. I hope it helps.
If you have libssl1.1, your problem may be that these older versions of ruby (2.4 is the cutoff) are only compatible with libssl1.0.
For debian/ubuntu, please ensure that apt-get install libssl1.0-dev succeeds.
If you are using ruby-install, it will take the same openssl argument as rvm:
ruby-install ruby-2.0.0-p247 -- --with-openssl-dir=/usr/local/opt/openssl
I'm trying to install rails on Ubuntu 10.10, but get File not found: lib every time. Ruby and Rubygems have been installed correctly. I've seen this problem posted all over the web but no solutions work for me. I reinstalled rdoc and I still get the same result.

I wrote a detailed how-to guide on installing Ruby and Rails on Ubuntu 10.10 that will help you with this.
Guaranteed, or your money back!
You should avoid the packaged version of Ruby (i.e., avoid the version of Ruby that comes from apt-get install ruby). The Debian packaging system (which Ubuntu uses) conflicts with what Ruby expects.
Instead, you should install Ruby from source.
There's a nice tool called RVM to help you do this.
# Install prerequisites
$ sudo apt-get install git curl wget
# Download and install RVM
$ bash < <( curl http://rvm.beginrescueend.com/releases/rvm-install-latest )
# Install RVM into your .bash_profile
$ cat >> ~/.bash_profile <<-PROFILE
> [[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm"
> PROFILE
# Load RVM into the current shell
$ rvm reload

# Install Ruby
$ rvm install ruby-1.9.2-p180 # latest version as of now
$ rvm use ruby-1.9.2-p180 --default
# Check it
$ ruby -v
$ which ruby
$ gem install rails
is there any way to install Ruby 1.9.2 or 1.8.7 + Rails 3 on my debian squeeze?
You probably don't want to use RVM on a production machine. Its $PATH magic will break in non-obvious places (e.g. cron jobs), and you'll be up a creek.
You could simply build from sources and use checkinstall to create a .deb for yourself. Here's a tutorial for Ubuntu that should translate pretty well into debian.
First install rubygems, I think it's the only Debian package. Then (as Ruby gems):
rvm (install with it ruby 1.9.2, or Ruby version you want)
bundler
rails
And then you can manage application gems with Bundler.
Have you looked at railsready-debian-lenny (it is claimed to work on Squeeze too)? Don't forget to install dependencies pointed in readme.md
The steps below outlines installing Ruby On Rails as a normal user.
Check first if the user has sudo rights. To do this try executing a simple command
$sudo ls -a
[sudo] password for unlimit:
unlimit is not in the sudoers file. This incident will be reported.
If you see a message like above, you will need to add the user to the sudoer file, this can be done by
$echo 'unlimit ALL=(ALL) ALL' >> /etc/sudoers
Check if you have ruby installed. Execute the command below
$ruby -v
-[bash]: ruby:command not found
If you see something like this, this means ruby is not installed. Install it
$sudo apt-get install ruby
Install additional libraries
$sudo apt-get install build-essential
$sudo apt-get install curl
$sudo apt-get install libssl-dev
Install rvm
$curl -L get.rvm.io | bash -s stable
Set the rvm path
$source $HOME/.rvm/scripts/rvm
You should add this to the .bashrc file.
Fetch the latest rvm and reload it
$rvm get head && rvm reload
Install ruby 1.9.3
$rvm install 1.9.3 --with-openssl-dir=$HOME/.rvm.usr
I needed to install the readline lib
$sudo apt-get install libreadline-dev
Get the rails gem
$gem install rails -v 3.2.3
Check if you have rails
$rails -v
Rails 3.2.3
Get the readline package
$rvm pkg install readline
Get sqlite3
$sudo apt-get install sqlite3 libsqlite3-dev
You are all set to create your first rails app
$rails new app HelloWorld
You can find more info http://unlimit.in/installing-ruby-on-rails-on-debian.html
The best way to install Ruby and any Gems you like is with RVM. It will compile the latest version of Ruby for you and give you tools to manage gemsets.
Relying on the distribution's packages is usually a bad idea, because they are typically out-of-date.
