我正在开始一个 Rails 教程,告诉我在创建新的演示应用程序时编辑 gemfile:
source 'https://rubygems.org'
gem 'rails', '3.2.3'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
gem :development do
gem 'sqlite3', '1.3.5'
end
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '3.2.4'
gem 'coffee-rails', '3.2.2'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
# gem 'therubyracer', :platform => :ruby
gem 'uglifier', '1.2.3'
end
gem 'jquery-rails', '2.0.0'
group :production do
gem 'pg', '0.12.2'
end
# To use ActiveModel has_secure_password
# gem 'bcrypt-ruby', '~> 3.0.0'
# To use Jbuilder templates for JSON
# gem 'jbuilder'
# Use unicorn as the app server
# gem 'unicorn'
# Deploy with Capistrano
# gem 'capistrano'
# To use debugger
# gem 'ruby-debug19', :require => 'ruby-debug'
当我尝试bundle install
使用文件时,bundle install --without production
按照说明使用,我收到此错误:
You need to specify gem names as Strings. Use 'gem "development"' instead.
当我返回文件并更改gem :development
为时,gem "development"
我被告知:
Could not find gem 'development (>= 0) ruby' in the gems available on this machine.
我是新手,当一组明确的指令似乎与另一组发生冲突并且两者都不起作用时,我真的不知道该怎么做,特别是因为我并不真正理解这些术语中的任何一个是什么意思。
非常感谢您的帮助,
