I want to download the latest Ruby release(version 3.0.0), using RVM but I am faced with the following error when running rvm install 3.0.0:
Unknown ruby interpreter version (do not know how to handle): 3.0.0
I have also tried 3 & 3.0, but gives the same error.
According to this page, it should be available through RVM. I'm already using RVM to manage my ruby versions, so I don't want to use rbenv ... nor do I want to install from source.
How can I get Ruby version 3.0.0 installed using RVM?
If you have not updated rvm do that first RVM Upgrading
rvm get stable
# or
rvm get master # for even newer versions not in stable 3.0.0 in this case
To see all available rubies run
rvm list remote all
# or
rvm list known # as pointed out in the comments
you should see ruby-3.0.0 in the list of available rubies
Then run
rvm install ruby-3.0.0
In many parts of the world, the current time is holiday time. RVM is maintained by unpaid volunteers in their spare time, who might choose to spend time with their families.
Therefore, it might take a while for a new release of RVM to come out.
Also, there are a couple of bugs related to YARV 3.0.0 not working on the RVM bug tracker, obviously those will need to be fixed before a new release of RVM that supports YARV 3.0.0 can be released.
According to the RVM offline installation docs, the required extension to install any Ruby version is .tar.bz2.
Taking a look at the Ruby's 3 FTP folder, the .tar.bz2 is available only for the preview1 release. Neither the rc1 nor the official has that extension available yet.
I think we gotta wait for some maintainer to update the FTP folder with that extension.
First you need to upgrade the RVM. Then try to install the needed version again ->
rvm get master && rvm install 3.0.0
You can just rename the .tar.gz file to be a .tar.bz2 and everything will work. Here's the steps:
As stated in previous answers, update rvm to the latest stable version with:
rvm get stable
Download the release 3.0.0 gz file from: https://cache.ruby-lang.org/pub/ruby/3.0/ruby-3.0.0.tar.gz
Move the downloaded file into your .rvm/archives folder and rename it to a .bz2 in the process:
mv ~/Downloads/ruby-3.0.0.tar.gz ~/.rvm/archives/ruby-3.0.0.tar.bz2
Make sure you've got at least gcc v8 installed, or newer. This is required due to the multi-threaded concurrency features of Ruby 3. I used gcc-10, which on my Mac I had installed with Homebrew. If you do use a newer version of gcc then you'll need to set the CC environment variable:
export CC=gcc-10
With everything now in place, install as usual, which will automatically find the appropriate .bz2 file in your archives folder:
rvm install ruby-3.0.0

My current Ruby version is 2.2.3 and I want to upgrade it to 2.3.0.
I use rbenv using this guide: gorails.com/setup/ubuntu/16.04
How do I upgrade my Ruby version? And when I upgrade, does it affect anything that I need to be aware of?
This answer had been written to address the original question, which did not specify rbenv as a preferred approach. Although the question changed after this answer was written, the answer has been retained to help users that may be using RVM to upgrade/manage their Ruby installations.
See the rbenv answer for details on using rbenv for the same purpose.
Use RVM or another Ruby version manager. This is far superior to installing a new system Ruby in most cases.
If you're upgrading your system Ruby, you have a number of things to keep in mind:
what other dependencies are there on that Ruby version?
are all of the gems going to be available after upgrade?
which applications are using the existing Ruby version and what can/will break after upgrade?
are there any other users using the existing Ruby that need to be aware of (and prepare for) the change?
With a Ruby version manager, you eliminate most of these concerns. You can run multiple Ruby versions on the same machine, which gives you the ability to test backward and forward compatibility. It also lets you experiment with the newer Ruby versions to make sure that they're fully stable for use.
You can install RVM using this method from any bash shell:
\curl -sSL https://get.rvm.io | bash -s stable
or update it to the most recent stable version by using:
rvm get stable
Once RVM is installed (or updated), you can install any Ruby version you choose, by doing the following:
rvm install 2.3.0
or upgrade from one version to another:
rvm upgrade 2.2.3 2.3.0
You can see which Ruby versions are installed by using this:
rvm list
You can also check to see which versions of Ruby that you can install on RVM by using this command:
rvm list known
Switch to a specific installed Ruby version by using the use command:
rvm use 2.3.0
and then switch back to an older version when you need to:
rvm use 2.2.3
Check out the RVM documentation for more features. You'll be surprised at how useful RVM actually is. There's a whole lot more to it than just what's shown here.
To upgrade your Ruby version using rbenv, you can use these steps. Some will only be necessary based on your environment. Plugins are an important aspect of this, if you have any installed.
Update rbenbv
First, you'll want to make sure that your rbenv version is updated. If you have the update plugin installed, you can update rbenv and all installed plugins using a single command:
rbenv update
Using the update plugin is highly recommended. However, if you are not using the update plugin, you can manually update rbenv in this way:
cd ~/.rbenv
git pull
Update plugins
If you have manually updated rbenv, you'll also need to update the plugins manually, as well. Make sure to follow the update instructions for each plugin.
One plugin that's very important to update at this point (if you have it installed) is the ruby-build plugin, which provides build support for Ruby under rbenv. This may improve the experience installing a new Ruby version in the next step.
Install Ruby version
After you have updated rbenv, you can install the new Ruby version:
rbenv install -v 2.3.0
Remove Ruby version
rbenv will allow you to manage and use multiple Ruby versions on a single machine. This is a huge benefit. However, if you no longer want the older Ruby version installed, you can remove it like this:
rbenv uninstall 2.2.3
Note that you can always re-install the Ruby version after uninstalling it, and use rbenv to manage the versions separately. This is good practice when working with multiple projects.
I already have ruby version 2.0 but for a project, I need version 1.9.3-p448. When I try to run the ruby build I get the following:
ruby-build: definition not found: 1.9.3-p448
You can list all available versions with `rbenv install --list'.
If the version you're looking for is not present, first try upgrading
ruby-build. If it's still missing, open a request on the ruby-build
issue tracker: https://github.com/sstephenson/ruby-build/issues
The highest 1.9.3 version that comes up when i run rbenv install --list is 1.9.3-p429 and I can't figure out how to do a manual install. All of the documentation I have read only has instructions from the start but nowhere addresses this issue.
I had a similar problem and I uninstalled ruby build then reinstalled it and it worked. Hope that works!
You need to upgrade rbenv. 1.9.3-p448 is available in the current version.
So far I only know how to do commands like
rvm 2.0.0
Fortunately Google tells me
The current stable version is 2.0.0-p247.
But shouldn't I be able to use rvm to do that step for me? I can't figure out how to just tell rvm to install the latest version of ruby, without manually specifying it.
it is enough to:
rvm get stable
rvm use ruby --install --default
it will update rvm, check for latest ruby - install it if missing - and set as default
I don't know of a way to have rvm just install the latest version automatically, but here's three simple commands using just rvm:
rvm reload
rvm list known # This will show all the available versions, including the latest
rvm install <latest_version> # Replace <latest_version> with the latest shown by the last command
rvm install ruby-head should install the last known version.
I just installed Ruby 2.0.0 using rbenv and set it to the global ruby version for my system. Since 2.0 is compatible with 1.9.3, I tried to start up a Rails project with it, but got the following error. I did rbenv rehash after installing 2.0
The `rails' command exists in these Ruby versions:
1.9.3-p327
Does this mean that every gem I installed on my system with 1.9.3 has to be reinstalled if I wish to use it with 2.0?
As seen here:
You need to reinstall bundler for each version of Ruby you use. See Ruby versions where you have it installed:
rbenv whence bundle
See your current version:
rbenv version
Install bundler for that version, if missing:
gem install bundler
Yes. Rbenv (and RVM) have separate "gem home" directories for each installed version of Ruby. There may be ways to symlink certain directories to get them to share, but this will likely lead to problems, particularly with gems that include native C extensions, which may or may not compile and run cleanly in multiple versions.
If you have a Gemfile, easiest thing is to just bundle install again for Ruby 2.0, giving you duplicate copies of many gems and Ruby-2.0 compiled versions of any native gems.
Another solution to this is to copy (or reinstall) the gems from your previous version to the newly installed version. How to do that is answered in detail in this question, which has two scripts -- one to install from local cache, one to reinstall from the internet (mine).
I have created a new user account on my mac and I am trying to update to the current version of ruby on it (1.9.2) from the snow leopard default of 1.8.7. Can somebody point me to tutorial or explain the best method to update Ruby on my mac from 1.8 to 1.9.2? Thanks
As The Tin Man suggests (above) RVM (Ruby Version Manager) is the Standard for upgrading your Ruby installation on OSX: https://rvm.io
To get started, open a Terminal Window and issue the following command:
\curl -L https://get.rvm.io | bash -s stable --ruby
( you will need to trust the RVM Dev Team that the command is not malicious - if you're a paranoid penguin like me, you can always go read the source: https://github.com/wayneeseguin/rvm ) When it's complete you need to restart the terminal to get the rvm command working.
rvm list known
( shows you the latest available versions of Ruby )
rvm install ruby-2.3.1
For a specific version, followed by
rvm use ruby-2.3.1
or if you just want the latest (current) version:
rvm install current && rvm use current
( installs the current stable release - at time of writing ruby-2.3.1 - please update this wiki when new versions released )
Note on Compiling Ruby: In my case I also had to install Homebrew Link to get the gems I needed (RSpec) which in turn forces you to install Xcode (if you haven't already) https://itunes.apple.com/us/app/xcode/id497799835 AND/OR install the GCC package from: https://github.com/kennethreitz/osx-gcc-installer to avoid errors running "make".
Edit: As of Mavericks you can choose to install only the Xcode command line tools instead of the whole Xcode package, which comes with gcc and lots of other things you might need for building packages. It can be installed by running xcode-select --install and following the on-screen prompt.

Note on erros: if you get the error "RVM is not a function" while trying this command,

I'll make a strong suggestion for rvm.
It's a great way to manage multiple Rubies and gems sets without colliding with the system version.
I'll add that now (4/2/2013), I use rbenv a lot, because my needs are simple. RVM is great, but it's got a lot of capability I never need, so I have it on some machines and rbenv on my desktop and laptop. It's worth checking out both and seeing which works best for your needs.
With brew this is a one-liner:
(assuming that you have tapped homebrew/versions, which can be done by running brew tap homebrew/versions)
brew install ruby193
Worked out of the box for me on OS X 10.8.4. Or if you want 2.0, you just brew install ruby
More generally, brew search ruby shows you the different repos available, and if you want to get really specific you can use brew versions ruby and checkout a specific version instead.
I know it's an older post, but i wanna add some extra informations about that.
Firstly, i think that rvm does great BUT it wasn't updating ruby from my system (MAC OS Yosemite).
What rvmwas doing : installing to another location and setting up the path there to my environment variable ... And i was kinda bored, because i had two ruby now on my system.
So to fix that, i uninstalled the rvm, then used the Homebrew package manager available here and installed ruby throw terminal command by doing brew install ruby.
And then, everything was working perfectly !
The ruby from my system was updated !
Hope it will help for the next adventurers !
I'll disagree with The Tin Man here. I regard rbenv as preferable to RVM. rbenv doesn't interfere drastically with your shell the way RVM does, and it lets you add separate Ruby installations in ordinary folders that you can examine directly. It allows you to compile Ruby yourself. Good outline of the differences here: https://github.com/sstephenson/rbenv/wiki/Why-rbenv%3F
I provide instructions for compiling Ruby 1.9 for rbenv here. Further, more detailed information here. I have used this technique with easy success on Snow Leopard, Lion, and Mountain Lion.
Dan Benjamin's Hivelogic article Installing Ruby, RubyGems, and Rails on Snow Leopard is the recommended place to go although the article is for 1.8, so here's a Ruby 1.9-specific install on Snow Leopard. Watch out for the 64-bit thing... either go all 64-bit 'fat' (as is - for example - Apache on OS X, which can cause problems with 32-bit libraries) or check any gems you're likely to use to make sure they're okay for 64-bit.
This command actually works
\curl -L https://get.rvm.io | bash -s stable --ruby
As previously mentioned, the bundler version may be too high for your version of rails.
I ran into the same problem using Rails 3.0.1 which requires Bundler v1.0.0 - v1.0.22
Check your bundler version using: gem list bundler
If your bundler version is not within the appropriate range, I found this solution to work: rvm #global do gem uninstall bundler
Note: rvm is required for this solution... another case for why you should be using rvm in the first place.
There are several other version managers to consider, see for a few examples and one that's not listed there that I'll be giving a try soon is ch-ruby. I tried rbenv but had too many problems with it. RVM is my mainstay, though it sometimes has the odd problem (hence my wish to try ch-ruby when I get a chance). I wouldn't touch the system Ruby, as other things may rely on it.
I should add I've also compiled my own Ruby several times, and using the Hivelogic article (as Dave Everitt has suggested) is a good idea if you take that route.
