Question

对于某些测试，我想尝试使用rails 5 alpha并使用生成器。

我只是创建一个新的应用程序（rails new test）

我更改了gemfile并添加/替换：

gem 'rails', github: "rails/rails"
gem 'arel', github: 'rails/arel'

我得到了这个错误：

~/c/test ❯❯❯ rails g model Model table_name:string model_name:string indexes:hstore
/Users/user/.rbenv/versions/2.2.2/lib/ruby/2.2.0/rubygems/dependency.rb:315:in `to_specs': Could not find 'railties' (>= 0) among 9 total gem(s) (Gem::LoadError)

如何安装轨道5的栏杆？

Answer 1

如果您按照以下步骤操作......

git clone https://github.com/rails/rails.git
cd rails/
bundle install
cd ../
./rails/railties/exe/rails new myapp --edge --dev

...然后cd进入myapp文件夹你应该看到......

ruby-2.2.2 marklocklear:myRails5App marklocklear$ rails -v
Rails 5.0.0.alpha

注意创建应用时的--edge和--dev选项应将Gemfile设置为指向正确的位置。

Answer 2

您可以将以下宝石列表添加到您的Gemfile中 -

gem 'rails', github: "rails/rails"

gem 'sass-rails', '~> 5.0'
gem 'uglifier', '>= 1.3.0'
gem 'coffee-rails', '~> 4.1.0'
gem "jquery-rails"
gem 'turbolinks', github: 'rails/turbolinks'

如果您想将postgresql用作数据库后端或其他，则可以使用Rails 5，turobolinks 3并添加pg。
