我正在尝试将我现有的rails app（3.0.3）更新为3.1.0.beta1。我已经安装了rails gem并运行bundle命令来引入所有更新的gem。当我运行rake rails:update但我得到：
rake aborted!
undefined method `join_asset_file_contents' for module `ActionView::Helpers::AssetTagHelper'
我做错了什么？
跟踪输出

答案 0 :(得分：1)
join_asset_file_contents方法从
移开actionpack/lib/action_view/helpers/asset_tag_helper.rb
到
actionpack/lib/action_view/helpers/asset_tag_helpers/asset_include_tag.rb
这就是您看到此错误的原因。
是否可以使用--trace运行rake命令以查看为什么在调用图中执行join_asset_file_contents？
