Unable to install RVM system-wide on Ubuntu 12.04

Question

I can do a user installation of RVM on Ubuntu 12.04 using the following command:

$ \curl -L https://get.rvm.io | bash -s stable --ruby

And it works.

However, I would like to do a system-wide install of RVM so it will be installed in /usr/local/rvm. But when I add sudo, the installation just hangs, like so:

$ \curl -L https://get.rvm.io | sudo bash -s stable --ruby
[sudo] password for guarddoggps:   % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100   184  100   184    0     0    475      0 --:--:-- --:--:-- --:--:--   828
100 20511  100 20511    0     0  30262      0 --:--:-- --:--:-- --:--:-- 30262

So how can I get a system-wide install on Ubuntu 12.04?

Answer 1

If I understand your question, you can either do the entire command as root with

sudo -i
curl -L https://get.rvm.io | bash -s stable --ruby

Or, break the command into two commands -

curl -L https://get.rvm.io > install.rb
sudo bash -s stable --ruby < install.rb
rm install.rb

Answer 2

Per the documentation :

For a Multi-User install you would execute the following:

user$ \curl -sSL https://get.rvm.io | sudo bash -s stable

There are instructions for using RVM all over the internet, but the only real, truly accurate, source is the RVM site itself. RVM is a fast-moving target and the internet is a vast heap of stale information, so trust the authors for information on how to install it or use it before you trust others.

It's really important to read the entire Installation page.
