Question

ActiveSupport requires Ruby version >= 1.8.7 on Ubuntu

Answer 1

A:

sudo apt-get install ruby-full should work

It says ruby-full is already the latest version.

It probably means that the sources for apt-get are set to an older version of Ubuntu distribution which isn't updated with newer versions of packages anymore. You'd probably have to change your `/etc/apt/sources.list` to point to a newer version.

Do you know which sources to update to? Thanks.

I guess you should just change the distribution name. For example if you have `http://www.domain.ext/path/to/repository lucid main`, then **lucid** is the name of a distribution (Lucid Lynx). You probably have some older one, just change it to some other release (see http://en.wikipedia.org/wiki/Ubuntu_(operating_system)#Releases), like lucid, in all the lines where it can be found.

Answer 2

A:

Try rvm ruby version manager , http://rvm.beginrescueend.com/ .you can have multiple versions of ruby and gems are shared or unique to each version.

I tried RVM, but couldn't get it to work. "Using" a different Ruby didn't change the system version. I installed the RVM gem, if that's the wrong approach...

If you use RVM, you should not use sudo when installing gems in RVM-installed rubies.
