Problem with loading the hpricot gem

Question

I have a problem with loading the hpricot gem. I'm using it in a rake task and put a require "hpricot" in it. But it doesn't load with a error message: no such file to load -- hpricot But I'll see it in my gem list but don't know why the rake task doesn't recognize it. Does anybody has experience with that kind of problem with the hpricot gem?

output of gem list -d hpricot :

Answer 1

I solved the problem. I forgot to add the hpricot gem to the gem file of my rails app. After I added the gem to the gemfile and ran a bundle install , everything works fine.

Answer 2

请先添加require 'rubygems'然后再要求使用hpricot。
