Ruby 2.0 is running, but Rails 4 doesn't see it.

[Alphonse 23]

What am I doing wrong??

****@ubuntu:~/ruby/things_i_bought$ rake db:migrate

Rails 4 prefers to run on Ruby 2.0.

You're running
ruby 1.8.7 (2011-06-30 patchlevel 352) [i686-linux]

Please upgrade to Ruby 1.9.3 or newer to continue.

Check:

$ which rake
$ `which rake` --version

I suspect you aren't executing the one in the Rails.root/bin directory.

ruby-2.0.0-p0/bin/rake

that's 2.0 correct?


Thanks for the help, BTW.

[Tamara Temple]

IDK. I'm out of ideas. :(

nope, thanks though

[Norbert Melzer]

Hmmm…

I don't see any output of `which ruby`, probably missordered PATH-variable? Please check.

sean@ubuntu:~/ruby/things_i_bought$ echo $PATH

and here's the relevent section of my .bashrc file:

PATH=$PATH:$HOME/.rvm/bin # Add RVM to PATH for scripting

[[ -s "$HOME/.rvm/scripts/rvm" ]] && . "$HOME/.rvm/scripts/rvm" # This
loads RVM

Also, when I type in `which ruby` it freezes the console.

"Also, when I type in `which ruby` it freezes the console. "

I think whatever ruby you think you're running is damaged.  Based on the rails output about needing 2.0 but having 1.8.7 I guessing you'ld be well served by uninstalling 2.0 and redoing the install.  How about if you type "ruby --version" in your console, does that also hang?

[Alphonse 23]

Okay, I tried that. I uninstalled all previous version of ruby with rvm.
Now the only version of ruby on my machine is 2.0:
sean@ubuntu:~/ruby$ rvm list

rvm rubies

=* ruby-2.0.0-p0 [ i686 ]

# => - current
# =* - current && default
# * - default

sean@ubuntu:~/ruby$

But, it's still not working. I also tried uninstalling and reinstalling
rails4 through gem. Now rails 4 is the only version of rails on my
machine. I think next I'll try uninstalling rake. Maybe it's rake.

Thanks anyway.

In that case you have a serious problem that is nothing to do with
ruby itself. All which does (AFAIK) is to look in the path for the
file to execute.

no that works. I was typing it with the grave accents. I guess grave
accents freeze my console.

sean@ubuntu:~$ which ruby
/home/sean/.rvm/rubies/ruby-2.0.0-p0/bin/ruby
sean@ubuntu:~$

Still, I don't know how to get Rails 4 to recognize Ruby 2....

1 check if you have .ruby-version file

2 check the contents of your Gemfile for references to ruby 1.8  or  Force it to use ruby 2.0

3 rm Gemfile.lock and rebuild

 

[Alphonse 23]

reinstalled rvm and rubygems. Now everything works.. Case closed. Thank
you everyone for the help. You have my eternal gratitude.
