Question

I’m new to Rails trying to complete this tutorial, but I can;t even get started.
http://ruby.railstutorial.org/ruby-on-rails-tutorial-book#sec-rails_server

I am at Step 1.2.5

I am supposed to start the server using: $ rails server

I’m getting this error whenever I try to run any rails command.

localhost:first_app home$ rails server
/usr/bin/rails:22: undefined method `gem' for main:Object (NoMethodError)

Running rails commands used to work, because I had completed other tutorials from other books in the past. However, somewhere along the steps in this tutorial something was messed up.

Is it possible that editing my bash_profile caused this?

My bash_profile looks like this now:

export PATH=/bin:/usr/bin:"$PATH"
[[ -s "$HOME/.rvm/scripts/rvm" ]] && source "$HOME/.rvm/scripts/rvm"  # This loads RVM into a shell session. 

I added this line to it: export PATH=/bin:/usr/bin:”$PATH” after following directions in step Listing 1.1. Creating a gem configuration file.

I’m not sure if this helps, but If I type:

$ which rails

I get:

/Users/home/.rvm/gems/ruby-1.9.3-p194@rails3tutorial2ndEd/bin/rails

Answer 1

typing

$  rvm use 1.9.3@rails3tutorial2ndEd --create --default. 

allowed me to continue.
