RVM supports most UNIX like systems and Windows (with Cygwin or Bash on Ubuntu on Windows). 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 GPG keys used to verify installation package:
The reason you can't do this is simple and two fold. Cd is not a program but an in-built command and sudo only applies to programs. Sudo foo means run the program foo as root. Sudo cd /path returns. Sudo: cd: command not found because cd is not a program. If it were possible to use sudo to cd to a protected directory then having run the command sudo cd /var/named you would be in that. Sudo apt-get install libmagic-dev libatlas-base-dev Then to compile the addon run the following from the root of the snowboy repository: npm install./nodemodules/node-pre-gyp/bin/node-pre-gyp clean configure build Compile a Java Wrapper # Make sure you have JDK installed. Cd swig/Java make.

∞Basic install∞Ubuntu
RVM have dedicated Ubuntu package, so please follow instructions posted here: https://github.com/rvm/ubuntu_rvm
If you need a different (newer) version of RVM, after installing base version of RVM check the Upgrading section.
∞Any other system
Install RVM (development version):
Install RVM stable with ruby:
Additionally with rails (poor man's railsinstaller):
Or with jruby, rails and puma:
To install without rubygems-bundler and rvm gems (and also remove those gems from both global.gems and default.gems):
To install with hirb gem (and also add it to global.gems):
To install with rails and haml gems (and also add them to default.gems):
Without autolibs:
For a progress bar when downloading RVM / Rubies:
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.
get.rvm.io is a redirect to https://raw.githubusercontent.com/rvm/rvm/master/binscripts/rvm-installer You could also use full path for the installer:
∞Installation
I recommend you read the installation script 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:
To get the latest development state:
Instruct RVM to not change the shell initializations files 'rc' / 'profile':
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:
Note: The Multi-User install instructions must be prefixed with the
sudo command. 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 asroot , rather than executing the installation instructions from a non-privileged user account.
Installing a specific version:
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 upgrading docs for more details on branch format.

Debugging installation process:
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:
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 important note regarding Multi-User Installs.
Please see the FAQ page for an important note regardingroot 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 upgrading docs.
∞2. Load RVM into your shell sessions as a functionSingle-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 :
Mixed mode (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 passenger 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:
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.
NOTE: Before reporting problems check
rvm notes as it might contain important information.
Congratulations! You have successfully installed RVM.∞Try out your new RVM installation
Below are some examples of how to install and use a Ruby under RVM.
Display a list of all
known rubies. NOTE: RVM can install many more Rubies not listed.
Install a version of Ruby (eg
2.1.1 ):
Use the newly installed Ruby:
Check this worked correctly:
Optionally, you can set a version of Ruby to use as the default for new shells. Note that this overrides the 'system' ruby:
