Installing RVM
RVM supports most UNIX like systems and Windows (with
or ). The basic requirements are bash, curl, gpg2 and overall GNU version of tools - but RVM tries to autodetect it and install anything that is needed.
Install GPG keys
As a first step install
used to verify installation package to ensure .
gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6BABB82D39DC0E3 7D2BAF1CF37B13EBD0E739499BDB
Note: hkp://keys.gnupg.net can sometimes timeout you may want to use different keyserver, for example:
hkp://pgp.mit.edu
Basic install
RVM have dedicated Ubuntu package, so please follow instructions posted here: /rvm/ubuntu_rvm
If you need a different (newer) version of RVM, after installing base version of RVM check the
Any other system
Install RVM (development version):
\curl -sSL https://get.rvm.io | bash
Install RVM stable with ruby:
\curl -sSL https://get.rvm.io | bash -s stable --ruby
Additionally with rails (poor man's ):
\curl -sSL https://get.rvm.io | bash -s stable --rails
Or with jruby, rails and puma:
\curl -sSL https://get.rvm.io | bash -s stable --ruby=jruby --gems=rails,puma
To install without rubygems-bundler and rvm gems (and also remove those gems from both global.gems and default.gems):
\curl -sSL https://get.rvm.io | bash -s stable --without-gems="rvm rubygems-bundler"
To install with hirb gem (and also add it to global.gems):
\curl -sSL https://get.rvm.io | bash -s stable --with-gems="hirb"
To install with rails and haml gems (and also add them to default.gems):
\curl -sSL https://get.rvm.io | bash -s stable --with-default-gems="rails haml"
\curl -sSL https://get.rvm.io | bash -s -- --autolibs=read-fail
For a progress bar when downloading RVM / Rubies:
echo progress-bar && ~/.curlrc
Point to be noted is, there is a backslash before curl.
This prevents misbehaving if you have aliased it with configuration
in your ~/.curlrc file.
If you're an existing RVM user and you don't want RVM to attempt to setup
your shell to load RVM, you can opt out of this at install time by exporting
rvm_ignore_dotfiles=yes, or opt out permanently by setting this in your rvmrc.

Installation explained
There are three different ways to install and configure RVM.
Single-User installations (recommended) -
For an isolated install within a user's $HOME, not for root.
Multi-User installations -
For server administrators -
For an installation usable by all users on the system -
Please note that Single-User supersedes Multi-User.
This also used to be called the System-Wide Install.
Using this type of installation without
knowledge how umask works is a big security risk.
Mixed mode installations -
For an installation usable by all users on the system -
with isolated rubies/gemsets within a user's $HOME.
Installation instructions are exactly the same as for
Multi-User installations, the difference is in users environment.

You could also use full path for the installer:
\curl /rvm/rvm/master/binscripts/rvm-installer | bash -s stable
Installation
I recommend you
yourself. This will give you a chance to understand what it is doing before
installing, and allow you to feel more comfortable running it if you do so.
1. Download and run the RVM installation script
Installing the stable release version:
\curl -sSL https://get.rvm.io | bash -s stable
To get the latest development state:
\curl -sSL https://get.rvm.io | bash
Instruct RVM to not change the shell initializations files 'rc' / 'profile':
\curl -sSL https://get.rvm.io | bash -s -- --ignore-dotfiles
Please note that from this point it is user responsibility to add sourcing rvm to appropriate files.
For a Multi-User install you would execute the following:
\curl -sSL https://get.rvm.io | sudo bash -s stable
Note: The Multi-User install instructions must be prefixed with the
However, once the install is complete, and the instructions to add users to the
rvm group is followed, the use of either sudo or rvmsudo is no longer required. The sudo command
is only to temporarily elevate privileges so the installer can complete its work. If you need to
use sudo or rvmsudo after the install is complete, some part of the install directions were not
properly followed. This usually is because people execute the install as root, rather than
executing the installation instructions from a non-privileged user account.
Installing a specific version:
\curl -sSL https://get.rvm.io | bash -s -- --version latest
\curl -sSL https://get.rvm.io | bash -s -- --branch [owner/][repo]
Prefix the 'bash' portion with 'sudo', of course, if you wish to apply
this to a Multi_user Install. Please feel free to check out our
for more details on branch format.
Debugging installation process:
\curl -sSL https://get.rvm.io | bash -s -- --trace
If the rvm install script complains about certificates
you need to follow the displayed instructions.
Single-User Install Location: ~/.rvm/
If the install script is run as a standard, non-root user, RVM will install into the current users's home directory.
Modification of user configuration files (*rc / *profile) - RVM by default will modify
user startup files, although it is not recommended you can disable automated process
and do this manually:
\curl -sSL https://get.rvm.io | bash -s -- --ignore-dotfiles
echo "source $HOME/.rvm/scripts/rvm" && ~/.bash_profile
Multi-User Install Location: /usr/local/rvm
If the install script is run prefixed with sudo, RVM will automatically
install into /usr/local/rvm. Please see the troubleshooting page for an
Please see the FAQ page for an
root only installs.
External tutorials
Note that that any outside tutorials are NOT supported whether they work or not.
Tutorials are great, however we have spent massive amounts of man hours debugging the installation process.
Please use the install process(es) from this site only, as this is the only supported installation types and methods.
To update an existing RVM installation
It is safe to simply re-run the installation script again, or you can
follow the .
2. Load RVM into your shell sessions as a function
Single-User:
The rvm function will be automatically configured for every user on the system if you install as single user.
Read the output of installer to check which files were modified.
Multi-User:
The rvm function will be automatically configured for every user on the system if you install with sudo.
This is accomplished by loading /etc/profile.d/rvm.sh on login.
Most Linux distributions default to parsing /etc/profile which contains
the logic to load all files residing in the /etc/profile.d/ directory.
Once you have added the users you want to be able to use RVM to the rvm group, those users MUST log out and back in
to gain rvm group membership because group memberships are only evaluated by the operating system at initial login time.
Zsh not always sources /etc/profile so you might need to add this in /etc/**/zprofile:
source /etc/profile
Mixed mode (user gemsets):
After following above instructions for Multi-User.
Select a user as a manager - he will be responsible for installing new
rubies. This user should never run the command introduced below. If
this happens, remove/rename the ${HOME}/.rvmrc, logout and then relogin.
Otherwise you won't be able to install/upgrade new rubies correctly.
For each user that want to use RVM, an additional command needs to be run (once) for each user:
rvm user gemsets
Gemsets created by these users will be hosted in their HOME directory.
It's not possible to use global gemsets from system without using tricks
like manually linking directories and they should not be used in mixed-mode.
Please bear in mind that 'system' in this context does not refer to your
distribution's ruby packages, but to the RVM Multi-User installation.
You have two possibilities to manage RVM. The first one is to add
managers to the rvm group. The second one is to use separate managers
with rvmsudo and privilege escalation. Note that it is not safe to use
rvmsudo from mixed mode user. Both can be mixed without any
side-effect. It is however very important to not enable mixed-mode
gemsets or rubies for the managers. RVM is using a custom umask
(umask u=rwx,g=rwx,o=rx) when installing gemsets, rubies, updating
itself, etc. This should not impact your system. But if you prefer to
avoid RVM messing around with your umask, you can comment the umask line
in /etc/rvmrc.
This mode should also works with passenger, please follow
instructions.
3. Reload shell configuration & test
Close out your current shell or terminal session and open a new one
(preferred). You may load RVM with the following command:
source ~/.rvm/scripts/rvm
If installation and configuration were successful, RVM should now load
whenever you open a new shell. This can be tested by executing the
following command which should output rvm is a function as
shown below.
type rvm | head -n 1
rvm is a function
NOTE: Before reporting problems check rvm notes as it might
contain important information.
Congratulations! You have successfully installed RVM.

Troubleshooting Your Install
When you run
curl -sSL https://get.rvm.io | bash -s stable
and got the notice
curl: (60) SSL certificate problem: unable to get local issuer certificate

More details here: http://curl.haxx.se/docs/sslcerts.html
ca-certificates need to be installed:
apt-get install ca-certificates
If you open a new shell and running:
type rvm | head -1
does not show rvm is a function, RVM isn't being sourced correctly.
Ensure that RVM is sourced after any path settings as RVM manipulates the path.
If you don't do this, RVM may not work as expected.
If you are using GNOME on Red Hat, CentOS or Fedora, ensure that the
Run command as login shell option is checked under the
Title and Command tab in Profile Preferences.
