版本号
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
Every command给我同样的问题：
铁路-o models.dot -M
铁路-a -i -o full_models.dot -M
铁路-M |点-Tsvg> models.svg
铁路-C | neato -Tpng> controllers.png
最佳答案
铁路不适用于Ruby 1.9.2和Rails 3.0.10。 Railroady是高级维护版本。
