Ubuntu新更新后rvm的Ruby安装问题

Question

I am on the way to install rails. I am using Ubuntu 12.04 LLTS

vipin@vipin-Satellite-C640:~$ uname -a
Linux 3.11.0-18-generic #32~precise1-Ubuntu SMP Thu Feb 20 17:54:21 UTC 2014 i686 i686 i386 GNU/Linux

First I followed this .

but when i tried

rails -v

The program 'ruby' can be found in the following packages:
 * ruby1.8
 * ruby1.9.1
Try: sudo apt-get install <selected package>  

I reinstall ruby by

vipin@vipin-Satellite-C640:~$ rvm reinstall 2.1.0

Now I tried

ruby -v

again same result

vipin@vipin-Satellite-C640:~$ ruby -v
The program 'ruby' can be found in the following packages:
 * ruby1.8
 * ruby1.9.1
Try: sudo apt-get install <selected package>

I tried to uninstall rvm

vipin@vipin-Satellite-C640:~$ sudo apt-get --purge remove ruby-rvm
[sudo] password for vipin: 
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package ruby-rvm is not installed, so not removed
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

UPDATE : I was able to successfully created apps with rails in Ubuntu. Now I updated and upgraded the Kernel.

You have broken version of RVM. Ubuntu does something to RVM that produces lots of errors, the only safe way of fixing for now is to:

sudo apt-get --purge remove ruby-rvm
sudo rm -rf /usr/share/ruby-rvm /etc/rvmrc /etc/profile.d/rvm.sh

open new terminal and validate environment is clean from old RVM settings (should be no output):

env | grep rvm

if there was output, try to open new terminal, if it does not help then restart your computer.

install RVM :

\curl -L https://get.rvm.io | 
  bash -s stable --ruby --autolibs=enable --auto-dotfiles

If you find you need some hand-holding, take a look at Installing Ruby on Ubuntu 12.04 , which gives a bit more explanation.
