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!

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.
How do I install RubyGems on my Mac?
I tried to run $ gem install rubygems-update with no luck . It returns
ERROR: While executing gem ... (Gem::FilePermissionError)
You don't have write permissions for the /Library/Ruby/Gems/2.0.0 directory.
Any help would be great. Thanks
I would highly suggest using a package manager and a Ruby Environment Manager.
On Mac:
brew update
brew install ruby
# If you use bash
echo 'export PATH=/usr/local/Cellar/ruby/2.4.1_1/bin:$PATH' >> ~/.bash_profile
# If you use ZSH:
echo 'export PATH=/usr/local/Cellar/ruby/2.4.1_1/bin:$PATH' >> ~/.zprofile
You can do that but I suggest using an Environment Manager for Ruby.
You have rbenv and RVM.
IMO go for rbenv:
brew install rbenv ruby-build
# bash
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bash_profile
echo 'eval "$(rbenv init -)"' >> ~/.bash_profile
# zsh
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.zprofile
echo 'eval "$(rbenv init -)"' >> ~/.zprofile
# list all available versions:
rbenv install -l
# install a Ruby version:
rbenv install 2.4.1
# set ruby version for a specific dir
rbenv local 2.4.1
# set ruby version globally
rbenv global 2.4.1
rbenv rehash
gem update --system
One more variant is to use brew-gem.
https://formulae.brew.sh/formula/brew-gem
https://github.com/sportngin/brew-gem
Just copy/paste from the documentation:
brew install brew-gem
Usage
brew gem install heroku
To install a specific version: brew gem install heroku 3.8.3
To install using a brew installed ruby(/usr/local/bin/ruby): brew gem install heroku --homebrew-ruby
And with a specific version: brew gem install heroku 3.8.3 --homebrew-ruby
To upgrade: brew gem upgrade heroku
To uninstall: brew gem uninstall heroku
To check information: brew gem info heroku
Note: Installed gems are listed in brew list with prefix of gem-, like gem-heroku.
After installing cocoapods as Tulon suggested the thing which worked for me was passing the --user-install flag to the gem install command e.g
gem install rubygems-update --user-install
from https://guides.cocoapods.org/using/getting-started.html#sudo-less-installation
You may have to install manually in which case (as per the official website):
Go to the official website and download the zip file
Unzip the file in a directory.
Then go to the directory in your terminal and run: ruby setup.rb
It is showing that you don't have the permission to write something in that directory. Instead use this directory :
sudo gem install -n /usr/local/bin cocoapods
It perfectly work for me.
(I am using macOS Sierra, version 10.12.6)
I'm using Rails 4.2 and wanted to update my Ruby version as well with rbenv.
I used Homebrew to install ruby-build and no matter how many times I try to update via brew, Ruby version 2.1.3 won't show when I run rbenv install --list.
Usually, follow these steps to install a new Ruby version with rbenv:
$ brew update
$ brew upgrade ruby-build
$ brew upgrade rbenv
Check which versions are available after updating:
$ ruby-build --definitions
Install a specific version (for example 2.1.3) with:
$ rbenv install 2.1.3
Or if you are interested into improved support for UTF8 characters in the irb console:
$ RUBY_CONFIGURE_OPTS=--with-readline-dir=`brew --prefix readline` rbenv install 2.1.3
After these steps I usually set the newest version as my global default:
$ rbenv global 2.1.3
If you installed rbenv and ruby-build with homebrew and when you do echo $(rbenv root), you get /usr/local/var/rbenv instead of /Users/<username>/.rbenv, here is how to fix the issue.
When you install rbenv with homebrew, homebrew says:
To use Homebrew's directories rather than ~/.rbenv add to your profile:
export RBENV_ROOT=/usr/local/var/rbenv
Don't do that. Remove that line from your profile. Make sure you refresh your terminal after.
Then remove any signs of rbenv in the /usr/local/var directory:
sudo rm -r /usr/local/var/rbenv
Now when I do echo $(rbenv root) I get /Users/<username>/.rbenv instead of /usr/local/var/rbenv.
That fixed it for me.
The recommended installation from (https://github.com/sstephenson/ruby-build) states that you should install ruby-build as an rbenv plug-in.
I uninstalled ruby-build via Homebrew (brew uninstall ruby-build)
Navigated to ruby-build on my local machine and deleted it
git clone https://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
Now, when I run rbenv install --list, I see Ruby 2.1.3. A quick installation of: rbenv install 2.1.3 and I am now free to use 2.1.3 where I like. This also worked for my teammate.
Please update by brew upgrade ruby-build and then you should see 2.1.3 in rbenv install --list
You need to update ruby build. After update you can install all current suported versions.
If you using rbenv installed via git use
cd "$(rbenv root)"/plugins/ruby-build && git pull
Or via home brew
$ brew upgrade ruby-build
$ brew upgrade rbenv
I installed rbenv via Homebrew on an OS X 10.9.3 MacBook Pro:
brew update
brew upgrade rbenv ruby-build
According to rbenv install --list on my laptop Ruby 2.1.0-dev is the latest.
Both rbenv and ruby-build are generally installed from Github by cloning; That's how the authors recommend we install it.
git clone https://github.com/sstephenson/rbenv.git ~/.rbenv
git clone https://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby-build
If you didn't do it that way I'd recommend that method. Then, you can simply do:
cd ~/.rbenv
git pull
cd plugins/ruby-build
git pull
If you have several plugins use:
cd plugins
for i in *
do
cd $i
git pull
cd -
done
I update every couple weeks just to pull in the latest fixes/changes.
I faced the same issue. I got the latest by running the following command:
brew upgrade --HEAD ruby-build
I had this issue on OS X 10.8.5 (so don't think OS related). I had tried updating rbenv & ruby-build via brew. 2.1.0-dev was still latest build available.
I had to force uninstall and re-install ruby-build via brew to fix the issue.
brew uninstall ruby-build --force
brew install ruby-build
I had the same issue. Even after running
brew upgrade rbenv ruby-build
I still didn't get ruby-2.1.2 on the available list.
Following how to update list of available ruby versions on linux, I updated ruby-build through the following commands
cd ~/.rbenv/plugins/ruby-build
git pull
(I'm using OS X 10.9.4 MacBook Air)
This happened to me today. "rbenv install -l' displays outdated list while "ruby-build --definitions" returns the correct list. The problem is fixed by executing following command:
rm -Rf ~/.rbenv/plugins/ruby-build
It seems there is an outdated version of ruby-build under ~/.rbenv/plugins. Not sure when it got generated.
This link
gives a good explanation of the two available options.
If you installed rbenv from the git repository:
$ cd ~/.rbenv/plugins/ruby-build
$ git pull
If you used Homebrew on OSX to install rbenv:
$ brew update
$ brew upgrade ruby-build
(Also running brew doctor might give you the exact solution.)
And if you have permission denied errors, this is my addition:
$ sudo chown -R $USER /usr/local; brew update
$ sudo chown -R $USER /usr/local; brew upgrade ruby-build
Then you'll be able to install the recent versions.
$ rbenv install --list
$ rbenv install 2.1.2
The selected answer will work fine, but the issue may have simply been caused by homebrew not having an up-to-date formula for ruby-build at the time. As of this posting, the appropriate ruby-build formula has been put into the latest version of homebrew. So running:
$ brew update
should get you version needed to get the latest ruby. Then, running rbenv install --list again should list 2.1.2 (and others).
So if anyone sees this later on, hopefully you can avoid having to maintain the individual repositories if you'd rather use homebrew for package management.
I've just updated ruby-build and ruby-install to latest versions and both have the latest ruby 2.1.2
Probably rbenv doing something nasty.
Following all the above, on OSX 10.11 it still wouldn't list the latest versions. What I did below worked for me- I removed the dir, re-installed from brew then I had to link in brew like this:
$ brew uninstall ruby-build --force
$ rm -Rf ~/.rbenv/plugins/ruby-build
and then
$ brew install ruby-build
$ brew link --overwrite ruby-build
and then I saw the most recent versions to build.
cd /home/[user]/.rbenv/plugins/ruby-build && git pull && cd -
Don't forget to replace [user] with your user
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 $SHELL -l
and that fixed the problem.
Answered on 2021
If you're getting that error, it's very likely you have accidentally skipped one of the installation instructions:
git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
echo 'export PATH="$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:
