我正在關注Michael Hartl's book Ruby on Rails 3 Tutorail中的demo_app。該演示是一個簡單的支架用戶名:字符串email:字符串Javascript不適用於javascrip_inlcue-tag Rails 3.2.2

我得到一個錯誤,在我的application.html.erb文件:

Errno::EINVAL in Users#index 
Showing ~/demo_app/app/views/layouts/application.html.erb where line #6 raised: 
Invalid argument - cscript //E:jscript //Nologo //U /tmp/execjs20120323-4388-1an85xw-0.js 2>&1 
(in ~/demo_app/app/assets/javascripts/users.js.coffee) 

3: <head> 
4: <title>DemoApp</title> 
5: <%= stylesheet_link_tag "application", :media => "all" %> 
6: <%= javascript_include_tag "application" %> 
7: <%= csrf_meta_tags %> 
8: </head> 
9: <body> 

如果我chnage 6號線到:

<%= javascript_include_tag "default" %> 

該程序將運行完美,除非它不會允許我刪除用戶(大概是因爲它沒有運行javascript)。

你可以發佈app/assets/javascripts/users.js.coffee的內容嗎?同時確保您遵循本書Rails 3.2的版本 - http://ruby.railstutorial.org/ruby-on-rails-tutorial-book?version=3.2 – 2012-03-23 20:27:17

嘗試取消註釋寶石 'therubyracer'並運行捆綁,也最好使用最後一個穩定版本的紅寶石

我刪除了關於therubyracer和bundle install的評論,運行時遇到了libv8 gem的問題。錯誤:「安裝libv8時發生錯誤(3.3.10.4),並且Bundler無法繼續。 請確保'gem install libv8 -v'3.3.10.4''在綁定之前成功。 – glennm 2012-03-24 18:35:30

到解除停止libv8:混帳克隆[email protected]:fractaloop/libv8 CD libv8 --init 捆綁安裝 束EXEC耙編譯 – 2012-03-24 18:48:41

說,即使我已經有了計劃好的工作,混帳子模塊更新我應該仍然按照你的建議取消註釋gem therubyracer和卸載libv8? – glennm 2012-03-24 18:57:01

我搜索了周圍其他問題,討論了寶石therubyracer。我找到了一個答案,表明了Said Kaldybaev在此提出的建議。這對我沒有用。但有另一個建議,從app/assets/javascripts/application.js文件中刪除代碼

//= require_tree . 

刪除代碼使應用程序工作(包括銷燬功能)。
