Question

I want to install ruby on my Linux Mint 12.

I am following this tutorial and this one.

when I run rvm install 1.9.3 I see this error:

Installing Ruby from source to: /usr/share/ruby-rvm/rubies/ruby-1.9.3, this may take a while depending on your cpu(s)...

ruby-1.9.3 - #fetching 
ruby-1.9.3 - #extracting ruby-1.9.3- to /usr/share/ruby-rvm/src/ruby-1.9.3
ERROR: Error running 'bunzip2 < '/usr/share/ruby-rvm/archives/ruby-1.9.3-.tar.bz2' | tar xf - -C /usr/share/ruby-rvm/tmp/rvm_src_4428', please read /usr/share/ruby-rvm/log/ruby-1.9.3/extract.log
ERROR: There has been an error while trying to extract the source.  
Halting the installation.
ERROR: There has been an error fetching the ruby interpreter. Halting the installation.

How to fix it?

EDIT: @ka8725

bunzip2 is installed. When i run cat /usr/share/ruby-rvm/log/ruby-1.9.3/extract.log

I see

ANOTHER EDIT @EVERYONE 🙂

here whats happening guys:

rvm requirements outputs unrecognized error etc. However rvm notes will show me the needed stuff that i should install. BUT when i install these things, rvm will be removed
and so i have to reinstall lol!! 🙂 once, twice, ten times, forever:) this what would happen

these are the packages that i need

 sudo apt-get install build-essential bison openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev

Answer 1

Uninstall and reinstall rvm with

bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)

For posterity, I’ll add that the part of the error that says

Installing Ruby from source to: /usr/share/...

is what got me thinking about a broken installation of rvm which, as I said, is normally entirely contained in the ~/.rvm directory.
