Install rvm Ruby on Rails and Ruby on Kali Linux

It’s not as simple as described on the rvm website. By some reason it’s just does not work on Kali Linux.

1. Clean up your system first

$apt-get autoremove

2.whereis ruby – we will install a new version and overwrite the existing version instead of removing it.

ruby: /usr/bin/ruby /usr/lib/ruby /usr/bin/X11/ruby /usr/share/man/man1/ruby.1.gz

If you still want to remove it by any reason then you can use these commands if you want but it’s not recommended ;). Try do $apt-get remove ruby

If ruby are installed from source then you need to do the following to remove them.

rm -rf /usr/local/lib/ruby
rm -rf /usr/lib/ruby
rm -f /usr/local/bin/ruby
rm -f /usr/bin/ruby
rm -f /usr/local/bin/irb
rm -f /usr/bin/irb
rm -f /usr/local/bin/gem
rm -f /usr/bin/gem

3. apt-get install build-essential zlib1g zlib1g-dev libreadline6 libreadline6-dev libssl-dev

This is for root user installation.

$\curl -L | bash -s -- --ignore-dotfiles --autolibs=0 --ruby

This will install latest ruby 2.1.0 in writing this post.

root@amiOs:/home/ami# source /etc/profile.d/
root@amiOs:/home/ami# type rvm | head -n 1
rvm is a function

Yes it’s installed correctly!

This is quite important

root@amiOs:/home/ami# ruby -v
ruby 2.1.0p0 (2013-12-25 revision 44422) [x86_64-linux]

Ruby is now also installed to the correct version.

Now switch to global and update your gems.

root@amiOs:/home/ami# rvm gemset use global
Using ruby-2.1.0 with gemset global
root@amiOs:/home/ami# gem outdated
bigdecimal (1.2.3 < 1.2.5)

$echo “gem: –no-document” >> ~/.gemrc

This is to speed up gem installation as we don’t need docs files.

We will create a gemset now.

root@amios:/home/ami# rvm use ruby-2.1.0@rails4.0 –create (two dashes this need to be –create instead of -create)

  1. Why when i turn off my pc and i turn on this when i put on the terminal
    appears this message
    bash: rails: no se encontró la orden

  2. Is your rvm installed corectly?
    have u try to type the below?
    type rvm | head -n 1

    This should display the following
    rvm is a function

    If it is not displaying then you may check the rvm website for correct installation and it seems you will need add a line to your bashrc so the rvm is loaded during system startup

  3. Hi everything seemed to go smooth but if i restart or exit it seems to disapeer no ruby or rails can u help pls.

    • What about this .
      have u tried source it after reboot and see id rvm is loaded.

      This seems to be rvm not loading into shell after reboot
      home/ami# source /etc/profile.d/
      root@amiOs:/home/ami# type rvm | head -n 1
      rvm is a function

  4. hi thabks for the fast reply the two command do work but i have to use them everytime i open a bash window. Is there a way to make to perminent.? thanks

    • easiest way would be include this “source /etc/profile.d/” into your .bash_profile . This can be found in your home directory

  5. hi that worked a treat thanks for ur help. Great tutorial by the way im a noob to kali and managed fine thanks again.

  6. I am having trouble as i keep getting an error

    Any help would be appreciated.

  7. This was very helpful, thanks! Oh, the one snag I hit was this command, which needs to be space dash dash create, like this, rvm use ruby-2.1.0@rails4.0 –create … I am new to linux, so, this wasn’t immediately obvious.

  8. Hey ! Nice guide there, will be donating soon !
    Btw, i wanted to know about the DEPRECATION WARNING, it goea like this:
    DEPRECATION WARNING: Support for Rails < 4.1.0 will be dropped. (called from at /opt/metasploit/apps/pro/ui/lib/metasploit/pro/ui.rb:16)

    I get this everytime i run msfconsole on my kali linux, can u please tell me the problem and how to fix this ?!

    • Have you tried update your Rails to latest version which is 4.2 at the moment to have this info not displayed? Probably that will be the easiest way to get rid of it as long as the rails version is checked when the file executed 🙂

  9. aMi: this is about the only page online that has ruby, rvm and rails all good to go whether on arch, debian etc.
    very good job, thank you, kind regards, k1blz

  10. Installation works fine.

    But when i restart my machine and run
    ruby -v
    i get
    bash: ruby: command not found
    Seems a path to be added on reboot.

  11. Looking to Question by @tooter and perfect reply from @aMiGa….
    I had a query and searched for HOW TO INCLUDE THAT LINE TO .bash_profile to make it work permanently.

    So, here is the trick;
    echo ‘source /etc/profile.d/’ >>~/.bash_profile
