Question

我正在使用will_paginate gem来获取类似ajax的“see-more”链接。它在开发中工作但在生产中失败。

在我的生产日志中，我得到：

NoMethodError (undefined method `page' for []:ActiveRecord::Relation):

我已经尝试过，在生产应用程序的根目录中键入：

grep will_paginate Gemfile.lock

并获得：

will_paginate (3.0.4)
will_paginate

cap bundle：安装不会在我的VPS上安装will_paginate失败，但是当我尝试明确要求'will_paginate'时，钢铁在开发中工作并且在生产中失败，但这次整个网站，不仅仅是我的行动已经使用了will_paginate。这需要在unicorn.log中触发错误：

No such file to load will_paginate (LoadError)

所以我认为will_paginate不会在我的VPS上正确安装他的目录和捆绑安装，但为什么呢？

我试着输入：

gem list

那里没有will_paginate。所以我明确地说，在我当前的应用程序目录中。 gem install will_paginate 而这也没有解决问题。

所以我 gem uninstall will_paginate 并再次“限制部署” 在我之后宝石清单再一次没有will_paginate

端

任何人都可以帮我解决这个问题吗？

或许有人知道如何将所有文件（will_paginate所需的文件）显式添加到rails app。所以没有gem will_paginate

会有效

我被绑在：

bundle exec gem list

并在列表中找到will_paginate（3.0.4）。这意味着它已安装但不适用于我的应用程序？

最后，漫长的不眠之夜结束了。食谱是：

gem update --system (on both: server and local machine)

将本地ruby版本更新为服务器上的ruby版本，反之亦然

cap deploy:setup (don't now if it is necessary, but it works for me)
cap deploy && cap deploy:restart

和BAMM，它有效。

问题出在红宝石版本中。他们是不同的本地/远程机器。
