我將在我的rails 3應用程序上使用可讀性gem。我不能使用它在應用程序內的github頁面http://github.com/sspinc/readability上建議,雖然它在ruby控制檯上工作正常。如何在Rails 3.0.x上使用可讀性gem?
在Ruby控制檯:
> require 'open-uri'
=> true
> require 'readability'
=> true
> doc = Nokogiri::HTML(open('http://google.com'))
=> #<Nokogiri::HTML::Document:0x81345324 name="document"
> doc.to_readable
=> #<Nokogiri::XML::Element:0x813299a8 name="html"
# (expected result without any error)
在鐵軌上的控制檯:
> doc = Nokogiri::HTML(open('http://google.com'))
=> #<Nokogiri::HTML::Document:0x81c2baec name="document"
# (and so on.. expected result)
> readable = doc.to_readable
SyntaxError: /Users/apraditya/.rvm/gems/ruby-1.8.7-p299/gems/readability-0.1.5/lib/readability/js/readability.js:2: syntax error, unexpected '='
if(typeof console !== 'undefined') {

我證實,這不是一個JavaScript語法錯誤。根據主動支持錯誤判斷,它無法加載依賴關係,我懷疑Rails未能加載可讀性使用所需的gem(如harmony,johnson和envjs)來處理Ruby中的javascript和DOM。
所以我的猜測可能是錯誤的Gemfile中?這裏是我當前的Gemfile:
source 'http://rubygems.org'
gem 'rails', '3.0.3'
gem 'devise', '~> 1.1.5'
gem 'haml', '3.0.24'
gem 'simple_form'
gem 'cancan'
gem 'will_paginate', '~> 3.0.beta'
gem 'feedzirra', :require => [ 'feedzirra' ]
gem 'loofah', '1.0.0.beta.1'
gem 'compass', '~> 0.10.4'
gem 'meta_where', '~> 0.9'
gem 'populator'
gem 'simple-navigation'
gem 'readability'
我曾嘗試加入:需要可讀性選項來指定和諧,約翰遜和envjs;並reran'捆綁安裝'沒有任何錯誤,但我仍然有同樣的錯誤。
我也檢查過config/application.rb以要求Gemfile中的所有gem。用這條線
Bundler.require(:default, Rails.env) if defined?(Bundler)
所以,回到這個問題,我怎樣才能在Rails 3.0.x上使用可讀性?我錯過了什麼?如果有問題,我正在使用MacOS 10.6.5。
謝謝
你有沒有有沒有解決這個問題?我有這個寶石類似的問題。 – 2011-02-13 19:36:44
