While trying to use Spork following Learn Web Development with the Ruby on Rails Tutorial, it seems that the installed gem does not put enough permissions to the executable. http://ruby.railstutorial.org/chapters/static-pages?version=4.0#sec-spork

gem uninstall guard-spork; gem uninstall sporkしてbundle installしなおすとパーミションの問題が再発してくれる。

/var/lib/gems/1.9.1/gems/spork-1.0.0rc3/bin/spork は誰が作っているのだろう

sudo gem uninstall spork で消える

sporkrb/spork#180

ActiveRecord::ConnectionNotEstablished はどうやって解消しましたか？教えていただけるとありがたいです。。。
