Error Parsing 'Gemfile'

Question

I am working on a learning rails project on

http://railsapps.github.io/installrubyonrails-mac.html

I am on the Rails Example Applications section, but when I run

bundle install --without production  

I receive this error:

 [!] There was an error parsing `Gemfile`: no .<digit> floating literal anymore; put 0 before dot - ruby ‘2.3.0’
              ^
    /Users/eric.park/workspace/learn-rails/Gemfile:2: syntax error, unexpected tFLOAT, expecting '('
    ruby ‘2.3.0’
                 ^. Bundler cannot continue.

     #  from /Users/eric.park/workspace/learn-rails/Gemfile:2
     #  -------------------------------------------
     #  source 'https://rubygems.org'
     >  ruby ‘2.3.0’
     #  gem 'rails', '4.2.5'
     #  -------------------------------------------

I am new to rails, so if anyone can explain what this error generally means, and how I can address it if it shows up again that would be really helpful.

Answer 1

It is the quotation problem.

Try manually typing the sentence again with either single quote or double quote.

ruby '2.3.0' or ruby "2.3.0"

This should fix it.
