Ruby 2.2.3 has been dead for a while and yet I've been asked to look at a legacy project in order to update and fix it.
I can't get 2.2.3 to install in order to get a local env up and running on either MacOS or Ubuntu.
The error seems to be down to an openssl rubygems issue:
from rubygems.install.log
Exception `LoadError' at /Users/user/.rvm/rubies/ruby-2.2.3/lib/ruby/2.2.0/rubygems.rb:1222 - cannot load such file -- rubygems/defaults/operating_system
Exception `LoadError' at /Users/user/.rvm/rubies/ruby-2.2.3/lib/ruby/2.2.0/rubygems.rb:1231 - cannot load such file -- rubygems/defaults/ruby
/Users/user/.rvm/src/rubygems-3.0.8/lib/rubygems/core_ext/kernel_require.rb:54:in `require': cannot load such file -- openssl (LoadError)
Does anyone have any suggestions on how proceed?
On MacOS using rbenv instead of rvm solves this issue and has allowed me to move onto another host of dependency issues.
$ brew update && brew upgrade
$ brew doctor
Solve all brew doctor warnings, then proceed further
$ brew uninstall ruby
$ brew install rbenv
$ brew install ruby-build
$ echo 'export RBENV_ROOT=/usr/local/var/rbenv' >> ~/.bash_profile
$ echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.bash_profile
$ rbenv install -l
$ rbenv install 2.2.3
$ rbenv global 2.2.3
I've been setting up some ruby dependencies throughout a day on my Lubuntu (18.04) in VM. I installed ruby 2.4.0 and then installed rbenv and set 2.4.0 as global version to be used (probably reverse order). Then I installed bundler and started installing dependencies for my Sinatra app. Since I needed some native extension I also installed libpq-dev via sudo apt-get install, installed pg gem and ran bundler again. And then I have
Command 'ruby' not found, but can be installed with:
sudo apt install ruby
Same with bundle or gem commands.
I can see that I have rbenv in /home/michalvantuch/.rbenv/bin/rbenv and also /home/michalvantuch/.rbenv/versions/2.4.0/.
My path:
/home/michalvantuch/.rbenv/plugins/ruby-build/bin:/home/michalvantuch/.rbenv/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games
My bash history:
bundle install
gem install pg -v '0.21.0' --source 'https://rubygems.org/'
vi /home/michalvantuch/.rbenv/versions/2.4.0/lib/ruby/gems/2.4.0/extensions/x86_64-linux/2.4.0-static/pg-0.21.0/mkmf.log
sudo apt-get install libpq-dev
gem install pg -v '0.21.0' --source 'https://rubygems.org/'
bundle install
gem list --local
cd /home/michalvantuch/.rbenv/bin/
ls -lah
C rbenv -> ../libexec/rbenv
cd rbenv -> ../libexec/rbenv
cd rbenv
cd ../libexec/
ls -lah
pwd
cd ..
I'm weary and not sure how to fix this. Did I mess up with the system privileges ?
Complete setup commands for rbenv in linux machines
Initial setup
git clone https://github.com/rbenv/rbenv.git ~/.rbenv
cd ~/.rbenv && src/configure && make -C src
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc
~/.rbenv/bin/rbenv init
check whether eval "$(rbenv init -)" is present in ~/.bashrc. If not present run the following command
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
Then,
source ~/.bashrc
mkdir -p "$(rbenv root)"/plugins
git clone https://github.com/rbenv/ruby-build.git "$(rbenv root)"/plugins/ruby-build
source ~/.bashrc
rbenv rehash
Now, rbenv installed. Now install your ruby version ( change the version below to your version). And set that to global version. (Use latest stable version as global as it is a good practice. You can set local versions differently depending on your working project)
rbenv install 2.5.1
rbenv global 2.5.1
Finished.
So, it turns out I figured it out myself.
What I was missing (rbenv doctor helped me) was to have shims in my PATH. Adding
eval "$(rbenv init -)"
did the trick.
I recently created a Linode server with Ubuntu 12.04 LTS
as the admin user aurelien I installed rbenv (in my case 1.9.3-p194 for my older rails 3.2 app).
Afterwhich I ran gem install passenger and was placed in the directory ~/.rbenv/shims
After that I ran rbenv rehash
and to install nginx:
I couldn't run passenger-install-nginx-module because it asked to use with sudo. When I tried sudo passenger-install-nginx-module it told me command not found.
Then I found this post PhilT's answer
and tried running sudo bash -c "source ~/.bashrc && passenger-install-nginx-module"
/home/aurelien/.rbenv/shims/passenger-install-nginx-module
I went through the entire passenger/nginx installation and pressed "enter" when it asked for the prefix directory.
in my root directory cd ~/home/aurelien and I can't find /opt/nginx.
Did it correctly create these directories?
The only directories/files I have on the root are these:
. .. apps .bash_history .bash_logout .bashrc .cache .gem .gitconfig .profile .rbenv .ssh .viminfo
EDIT: My .bashrc file
export RBENV_ROOT="${HOME}/.rbenv"
if [ -d "${RBENV_ROOT}" ]; then
export PATH="${RBENV_ROOT}/bin:${PATH}"
eval "$(rbenv init -)"
fi
# If not running interactively, don't do anything
[ -z "$PS1" ] && return
The answer posted before by PhilT had the correct code for installing nginx together with passenger:
gem install passenger
rbenv rehash
sudo bash -c "source ~/.bashrc && passenger-install-nginx-module"
The fault in your explanation above is that /opt/nginx is not in user's home directory (~/home/aurelien/opt/nginx), but in the root directory (plainly /opt/nginx.), as nginx is a system-wide install.
(Note: In some other systems nginx also has config files placed in /etc/nginx instead)
In Ubuntu 10.04 I just installed rbenv.
The install command is not present.
rbenv 0.4.0-49-g8b04303
Usage: rbenv <command> [<args>]
Some useful rbenv commands are:
commands List all available rbenv commands
local Set or show the local application-specific Ruby version
global Set or show the global Ruby version
shell Set or show the shell-specific Ruby version
rehash Rehash rbenv shims (run this after installing executables)
version Show the current Ruby version and its origin
versions List all Ruby versions available to rbenv
which Display the full path to an executable
whence List all Ruby versions that contain the given executable
See `rbenv help <command>' for information on a specific command.
For full documentation, see: https://github.com/sstephenson/rbenv#readme
What am I missing?
The install command is not embedded into rbenv, it comes from the ruby-build plugin. You can install it using the command:
git clone https://github.com/rbenv/ruby-build.git "$(rbenv root)"/plugins/ruby-build
On Mac OS X you can install it through homebrew:
brew install ruby-build
On Debian (version >= 7) and Ubuntu (version >= 12.10) both rbenv and ruby-build can be installed using apt-get (or aptitude):
sudo apt-get update
sudo apt-get install rbenv ruby-build
On FreeBSD ruby-build is available in the Ports Collection, it can be install both as a binary package or build from the port:
# Using pkgng rbenv will be installed
pkg install ruby-build
# Building ruby-build form Ports will install rbenv only if the RBENV option is set
cd /usr/ports/devel/ruby-build
make install
I found that when using rbenv from a global directory, it's necessary to export the RBENV_ROOT variable, otherwise it won't load the plugins.
export RBENV_ROOT="/usr/local/rbenv"
if [ -d "${RBENV_ROOT}" ]; then
export PATH="${RBENV_ROOT}/bin:${PATH}"
fi
As everyone mentioned problem is missing ruby-build. For older versions of OS ruby-build may not be available as an apt package. In that case install using original instructions, which should've omitted the word Optional in this:
(Optional) Install ruby-build, which provides the rbenv install
command that simplifies the process of installing new Ruby versions.
git clone git#github.com:rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
# OR use http
git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
Simply install ruby-build in ubuntu:
sudo apt-get install ruby-build
And add
eval "$(rbenv init -)"
To your ~/.bashrc
I had installed the ruby-build plugin before and installed ruby 1.9.3-p327 using
$ rbenv install 1.9.3-p327
A few days later I tried to install ruby 2.0.0-p247 using
$ rbenv install 2.0.0-p247
but I received the error message
rbenv: no such command 'install'
All I had to do was to run
$ exec $SHELL -l
and that fixed the problem.

If you're getting that error, it's very likely you have accidentally skipped one of the installation instructions:
git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
exec $SHELL
Replace .bashrc with whatever shell you're using, for example .zshrc, or just manually access your shell config file and paste this line:
export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"
I strong advise against re-installing/installing Ruby via brew or apt-get just to get around this issue. The whole point of using rbenv is to make your life easier in future when there is ruby version upgrade, or when you're working on different rails projects that require different version of ruby.
It looks like ruby-build is not present. Run this command :
git clone https://github.com/rbenv/ruby-build.git "$(rbenv root)"/plugins/ruby-build
Anyone finding their way here with this issue on OSX and already having installed ruby-build via homebrew (like me), you may solve this by just upgrading ruby-build:
brew update
brew upgrade ruby-build
This fixed the problem for me.
This issue also happens in Linux when doing a stand-alone installation of ruby-build, if the ruby-build executable is not found in the path. If installing under /usr/local, try for example:
PATH=/usr/local/bin:$PATH /usr/local/bin/rbenv install ...
I came to this solution, but looking for a macOS solution that uses MacPorts.
So, here the same command using MacPorts:

I have tried to follow the installation instructions from:
Github Gollum
I have a fresh lion install and installed xcode command line tools. Then I did the following:
homebrew < -- ran script from website
brew doctor
brew install git
brew install rbenv
brew install ruby-build
echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
rbenv install 1.9.3-p362
rbenv rehash
rbenv global 1.9.3-p362
gem install gollum
mkdir ~/gollum_test
cd ~/gollum_test
git init
gollum
I get -bash: gollum: command not found
I'm new to all the tools above, so I don't know what I've missed.
Solved, I had to run
rbenv rehash
again!
