I followed instructions on PDF where it says to execute:

sudo gem install rails –version=5.0.0.rc2 –no-ri –no-rdoc

but still when I do “rails –version” I get: Rails 4.2.5

Book it is not clear about how to change from the default install (Rails 4.2.5) to the one we installed with command given here.

Did you do the rm -rf * per the instructions? If not, you still have a Gemfile around that points to the old version of Rails. This command can be done after the gem install rails.

Oh,,, you are totally right, this worked. My bad, I guess it was too late at night when I was going over instructions lol.

Now, since I’m going over the electronic version of it I would have expect commands like rm -rf to be highlighted kind of like is done at $ sudo gem install rails --version=5.0.0.rc2 --no-ri --no-rdoc

Maybe that’s a good feedback or idea to enhance electronic version ?

Book is great and support is awesome, thank you so much.
