由于Ruby on Rails是基于Ruby构建的,我担心在任何环境中使用Ruby构建软件是否相同.至少存在适用于Windows,Linux和Mac的Ruby版本.
那么,你可以用Ruby应用程序和Java应用程序做同样的事情吗？换句话说,跨平台是如何Ruby的？
编辑:我的意思是Ruby本身,而不是像jRuby一样在另一个虚拟机中运行Ruby .我是否期望在Ruby中开发比Java更多的跨平台陷阱或两者几乎相同？
我很抱歉询问可能是一个补救问题,但在学习rails时我试图按照本教程中的注释说明:
http://guides.rubyonrails.org/getting_started.html
我昨晚在本教程中发布了一个类似的问题并得到了一个迅速的回复,这对我帮助很大,所以我希望也能如此.先感谢您.
第5.14节:删除帖子
我被指示向index.html.erb页面添加删除链接
<h1>Listing Posts</h1>
<table>
<tr>
<th>Title</th>
<th>Text</th>
<th></th>
<th></th>
<th></th>
</tr>
<% @posts.each do |post| %>
<tr>
<td><%= post.title %></td>
<td><%= post.text %></td>
<td><%= link_to 'Show', post_path %></td>
<td><%= link_to 'Edit', edit_post_path(post) %></td>
<td><%= link_to 'Destroy', post_path(post),
method: :delete, data: { confirm: 'Are you sure?' } %></td>
</tr>
<% end %>
</table>
产生:
<td><a data-confirm="Are you sure?" data-method="delete" href="/posts/1" rel="nofollow">Destroy</a></td>
对我来说看起来不错,但是当我点击链接时,我既没有得到确认也没有指向删除操作.它会生成此HTTP操作

首先,我是一个完全初学者的轨道(只是为了让你得到我的初学者:我觉得自己只是在这里张贴的专家)这是我的第一个问题,所以请原谅我,如果我不是很明确.
所以,我是一个Windows 7用户,学习使用One Month课程的rails,我在尝试时遇到错误:

但我不知道该怎么做。那么我究竟如何“安装”一个 JavaScript 运行时呢？
这里也是我的 GemFile：
