Hirb没有正确显示在Rails 4中

Question

我安装了Hirb，并希望它附带漂亮的表格视图。 我检查过pry，Rails和Hirb的版本，他们应该工作。我也试图重新安装宝石。运行Hirb.enable后，我看不到漂亮的视图：

➜  awections git:(master) ✗ rails c
/Users/RJ/.rvm/gems/ruby-2.1.3/gems/activesupport-    4.2.0/lib/active_support/dependencies.rb:274:in `require'
2.1.3 (main):0 > Hirb.enable
=> true
2.1.3 (main):0 > Product.all
  Product Load (1.0ms)  SELECT "products".* FROM "products"

任何见解都将受到赞赏。
