ruby-on-rails – Rails 5,主分支,使用发生器

对于某些测试,我想尝试rails 5 alpha并使用发生器.

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)

如何为轨道5安装铁路？

如果您按照这些步骤…

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

注意创建应用程序时的–edge和–dev选项应该将Gemfile设置为指向正确的位置.
