【问题描述】：

我开始使用 best_in_place gem。它在我的本地开发机器上运行良好，但是当我将代码部署到生产服务器时，我得到：

ActionView::Template::Error (undefined method `best_in_place' for #<#<Class:0xc088ef8>:0xba694a0>):
    76:               <% t.each do |ticket| %>
    77:                 <tr>
    78:                   <td><%= check_box_tag "tickets[ids][]", ticket.id, false, :class => "status_change" %></td>
    79:                   <td><%= best_in_place ticket, :position, {:inner_class => "input-mini", :type => :input} %></td>
    80:                   <td><%= ticket.id %></td>
    81:                   <td><%= ticket.job_number %></td>
    82:                   <td><%= link_to ticket.name, edit_ticket_path(ticket) %></td>
  app/views/tickets/index.html.erb:79:in `block (3 levels) in _app_views_tickets_index_html_erb___947812068_98658810'
  app/views/tickets/index.html.erb:76:in `block (2 levels) in _app_views_tickets_index_html_erb___947812068_98658810'
  app/views/tickets/index.html.erb:56:in `each'
  app/views/tickets/index.html.erb:56:in `block in _app_views_tickets_index_html_erb___947812068_98658810'
  app/views/tickets/index.html.erb:50:in `_app_views_tickets_index_html_erb___947812068_98658810'
  app/controllers/tickets_controller.rb:11:in `index'

好像没有安装gem。我确实确保我做了bundle install。

查看：

<td><%= best_in_place ticket, :position, {:inner_class => "input-mini", :type => :input} %></td>

【问题讨论】：

能否确认gem是否从Gemfile.lock安装？
gem 在 gemfile.lock 中列出
你能把 Gemfile 贴在你包含它的地方吗？
我刚刚编辑了我的问题以包含它
ssh 进入您的服务器并捆绑打开 best_in_place。如果它出错，则 bundle 不知道它。

【解决方案1】：

我最终不得不重启服务器并独立重启乘客。在此之后， best_in_place 起作用了。我不确定为什么会这样，但如果有人愿意扩展可能发生的事情，我会更改他们解决方案的正确答案。
