Question

I’m a beginner to Ruby on Rails tutorials and the last thing I did was create a new app, generate scaffolding without Tests (- T flag), installed RSpec, and initiated a git repo in the folder.

That was two hours ago. I open my laptop up, try to run:

 rails server

Now I’m seeing this error:

/Users/reneruiz/.rvm/rubies/ruby-1.9.2-p180/lib/ruby/site_ruby/1.9.1/
  rubygems/requirement.rb:72:in 'parse': Illformed requirement ["0.7.1."] (ArgumentError)

The full stack trace is here: http://cl.ly/4pQC

I did some Google searches and I can’t seem to find anyone else with the same problem.

I don’t know how or where to go from here. Would seriously appreciate some help.

Answer 1

Check your Gemfile for version requirements that look like “0.7.1.” It looks like Bundler is trying to check for a gem with a certain version and is choking on the trailing period. If you find the version in your Gemfile, fix it and then run bundle install on the command line, and see if it’ll start.
