更新: 科林建议删除行// = require_tree.已经解决了这个问题.
我已经浪费了2天时间试图跟踪每个建议并解决我的问题.我试图按照Windows机器上的http://ruby.railstutorial.org书籍,并且不能为我的生活经历以下讨厌的错误.

我已经尝试了所有的建议,包括用msi安装nodejs,使用execjs 1.3.0和其他我甚至不记得的东西.这是gem文件
source 'https://rubygems.org'
gem 'rails', '3.2.8'
gem 'bootstrap-sass', '2.0.0'
gem …我正在通过入门教程(创建一个博客)和link_to Destroy无法正常运行.在终端中,它总是将其解释为#SHOW.
在阅读类似问题时,我了解到删除必须转换为POST以供浏览器解释.这似乎没有发生.
我也在Lynda.com Rails课程中使用Destroy遇到了同样的问题,所以它让我相信它是我开发环境中的东西.我在MacBook Pro Lion上使用Rails 4,Ruby 2.00p274,MySQL,WEBrick作为HTTP服务器.
在选择Destroy时的终端会话中:
Started GET "/posts/4" for 127.0.0.1 at 2013-08-09 13:45:20 -0600
Processing by PostsController#show as HTML
Parameters: {"id"=>"4"}
Post Load (0.6ms) SELECT "posts".* FROM "posts" WHERE "posts"."id" = ? LIMIT 1 [["id", "4"]]
Rendered posts/show.html.erb within layouts/application (0.4ms)
Completed 200 OK in 13ms (Views: 8.6ms | ActiveRecord: 0.6ms)
在ports-controller.rb中:
def destroy
@post = Post.find(params[:id])
@post.destroy
redirect_to action: :index
end
在index.html.erb中:
<% @posts.each do |post| %>
<tr>
<td><%= post.title %></td>
<td><%= post.text %></td> …我正在尝试将登录注销功能添加到我的rails应用程序中.为此,我添加了bcrypt用于密码加密的gem以及访问控制器.现在当我在本地运行它时,我收到一条错误消息.在添加上述功能之前,我的应用运行正常.
