捆绑安装不适用于gem'sqlite'和'pg'

Question

I was about to deploy my app so i was updating the gem file to be.

group :development do
  gem ‘sqlite3’
end

group :production do
  gem ‘pg’
  gem 'rails_12factor'
end

When i run the bundle install i get an error saying 'Undefined local variable or method `'sqlite3'' for Gemfile' which is weird because previously sqlite was the only gem in the file.

Thanks

Use single ' or double quotes " around gem names like you've done for rails_12factor . Update your Gemfile as follows:

group :development do
  gem 'sqlite3'
end

group :production do
  gem 'pg'
  gem 'rails_12factor'
end
