在环顾四周的时候，我遇到过很多类似问题的帖子，但是没有人真的解决了这个问题。该修复程序确保您指定rails new的版本。
在确定我指定了哪个版本的rails之前。运行命令bundle exec rails g locomotive:install给了我所有类型的错误消息。
$bundle exec rails g locomotive:install
Usage:
rails new APP_PATH [options]
Options:
-r, [--ruby=PATH] # Path to the Ruby binary of your choice
我正在做的另一个错误：
rails (= 3.2.17) ruby depends on
railties (= 3.2.17) ruby depends on
rdoc (~> 3.4) ruby
sdoc (~> 0.4.0) ruby depends on
rdoc (4.0.0)
以下是终端的副本。万一有人陷入同一陷阱。

Problem:
No configuration could be found for a session named 'default'.
Summary:
When attempting to create the new session, Mongoid could not find a session configuration for the name: 'default'. This is necessary in order to know the host, port, and options needed to connect.
Resolution:
Double check your mongoid.yml to make sure under the sessions key that a configuration exists for 'default'. If you have set the configuration programatically, ensure that 'default' exists in the configuration hash.
create config/initializers/locomotive.rb
create config/initializers/carrierwave.rb
create config/initializers/dragonfly.rb
create config/mongoid.yml
route
mount Locomotive::Engine => '/locomotive', as: 'locomotive' # you can change the value of the path, by default set to "/locomotive"
remove public/index.html
===============================================================================
The Locomotive Engine has been correctly installed in your Rails application.
1. Edit the main config files:
- config/initializers/locomotive.rb
- config/initializers/carrierwave.rb
- config/initializers/dragonfly.rb
- config/mongoid.yml
- config/devise.yml
- config/routes.rb
2. Launch the server
> bundle exec unicorn_rails
3. Open your browser
> open localhost:8080
4. Follow the installation wizard steps
5. Enjoy !
这是Gemfile：
source 'https://rubygems.org'
gem 'locomotive_cms', '~> 2.4.1', :require => 'locomotive/engine'
gem 'rails', '3.2.17'
# Bundle edge Rails instead:
# gem 'rails', :git => 'git://github.com/rails/rails.git'
# Gems used only for assets and not required
# in production environments by default.
group :assets do
gem 'sass-rails', '~> 3.2.3'
gem 'coffee-rails', '~> 3.2.1'
gem 'compass-rails', '~> 1.1.3'
# See https://github.com/sstephenson/execjs#readme for more supported runtimes
gem 'therubyracer', :platforms => :ruby
gem 'uglifier', '>= 1.0.3'
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 'debugger'
答案 0 :(得分：1)
必须从rails目录中调用$ bundle exec rails g locomotive：install
。所以对于机车：
rails _3.2.17_ new myapp --skip-active-record --skip-test-unit --skip-javascript --skip-bundle
cd myapp
bundle
bundle exec rails g locomotive:install
然后按照说明编辑配置文件。
mongoid.yml生成器缺少默认值：＆amp; defaults条目。应该是：
defaults: &defaults
sessions:
default:
database: myapp_prod
username: name
password: pass
hosts:
- host:port
options:
identity_map_enabled: true
development:
sessions:
default:
database: myapp_dev
username: name
password: pass
hosts:
- host:port
options:
identity_map_enabled: true
test:
sessions:
default:
database: myapp_test
username: name
password: pass
hosts:
- host:port
options:
identity_map_enabled: true
production:
sessions:
default:
database: myapp_prod
username: name
password: pass
hosts:
- host:port
options:
identity_map_enabled: true
机车在开发中使用独角兽：
bundle exec unicorn_rails启动服务器
