铁路不工作。给我带来问题，即 /railroad-0.5.0/lib/railroad/app_diagram.rb:54:in `disable_stdout'：未初始化的常量

Question

这是各种输出

railroad -M | dot -Tsvg > models.svg
/Users/me/.rvm/gems/ruby-1.9.2-p290/gems/railroad-0.5.0/lib/railroad/app_diagram.rb:54:in `disable_stdout': uninitialized constant AppDiagram::PLATFORM (NameError)

版本

me$ ruby -v
  ruby 1.9.2p290 (2011-07-09 revision 32553) [x86_64-darwin11.1.0]
me$ rvm -v
  rvm 1.8.0 by Wayne E. Seguin ([email protected]) [https://rvm.beginrescueend.com/]

me$ rails -v
  Rails 3.0.10

每个命令 都给了我同样的问题：

• railroad -o models.dot - M

• 铁路 -a -i -o full_models.dot -M

• 铁路 -M |点-Tsvg> models.svg

• -C |尼托-Tpng>控制器.png

Answer 1

Railroad 不适用于 ruby​​ 1.9.2 和 Rails 3.0.10。 Railroady 是高级维护版本..

Answer 2

编辑 /Users/me/.rvm/gems/ruby-1.9.2-p290/gems/railroad-0.5.0/lib/railroad/app_diagram.rb 第 54 行，并将 PLATFORM 更改为 RUBY_PLATFORM。
