Gemfile:22: 语法错误，意外的 tIDENTIFIER，期望输入结束

Question

When I run bundle install against the gemfile source below, I get a gemfile syntax error that points to the 'better errors' gem which is the second to last line.

When I run ruby -c Gemfile. I get the following message

Gemfile:22: syntax error, unexpected tIDENTIFIER, expecting end-of-input gem 'better_errors'

Any ideas?

source 'https://rubygems.org' 
ruby '2.0.0'
gem 'rails', '4.0.0'
 # Rails defaults
gem 'sqlite3'
gem 'sass-rails', '~> 4.0.0' 
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.0.0' 
gem 'jquery-rails'
gem 'turbolinks'
gem 'jbuilder', '~> 1.2'

# learn-rails
gem 'activerecord-tableless' 
gem 'bootstrap-sass'
gem 'figaro'
gem 'gibbon'
gem 'google_drive'
gem 'high_voltage'
gem 'simple_form', '>= 3.0.0.r  
group :development do
    gem 'better_errors'
    gem 'quiet_assets'
end 

Thank you for any assistance and time.

Answer 1

You missed the closing ' here :

gem 'simple_form', '>= 3.0.0.r <~~~
group :development do
    gem 'better_errors'
    gem 'quiet_assets'
end

Corrected

gem 'simple_form', '>= 3.0.0.r'
group :development do
    gem 'better_errors'
    gem 'quiet_assets'
end

Answer 2

After your version number specification for gem "simple_form" :

">= 3.0.0.r\ngroup :development do\n    gem "

(which is already invalid), you cannot continue another token better_errors without having a comma (which would be invalid anyway).
