ruby 2.0 rails gem install error “cannot load such file — openssl”

Question

I am using osx 10.8.2 installed ruby 2.0 and.... got this when trying to run \"sudo gem install rails\"

$         


        

Answer 1

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.

Answer 2

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.

Answer 3

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.

Answer 4

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

1. 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.

Answer 5

This worked for me which is similar to some of the other answers already posted.

rvm pkg install openssl
rvm reinstall all --force

Answer 6

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
