Question

I’ve been doing it over and over again on my Ubuntu1104 machine and something always keeps driving me nuts, like:

The program 'ruby' is currently not installed.  You can install it by typing:
sudo apt-get install ruby

And that even after installing ruby, which clearly stated “installed successfully”.
Also:

rvm list 

tells me:

rvm rubies

    ruby-1.9.2-p290 [ i686 ]

This:

which ruby
which gem

returns nothing.

So can someone please state the correct order to install ruby and it’s gems like rails and juggernaut. I believe that I have trouble with paths (the system can’t find successfully installed goodies) and rights (sometimes have to sudo and sometimes not, wich might be the cause for the path trouble I have). So please also give clear instructions on where to install and which rights to use.

I thought it’s RVM first (as stated in http://beginrescueend.com/rvm/install/):

1) bash < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer )
2) bash < <(curl -sk https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)
3) echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function' >> ~/.bash_profile

And then Ruby (which also installs gem):

4) rvm 1.9.2

And then the gems like rails and juggernaut

5) gem install rails
6) gem install juggernaut
...

Unfortunately I get a message as posted above, ‘gem not installed’ and ‘ruby not installed’.

Plus you can also install ruby first and then install RVM as a gem… confusing…

Cheers mates!

Answer 1

you did not intsalled rmv correctly:
what does

user$ type rvm | head -1
rvm is a function

If this is not what you see, then do :

echo '[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # Load RVM function' >> ~/.bashrc

restart bash and try again

after do

rvm --default use 1.9.2
