ruby-on-rails - Capistrano 3 + Sprockets 3 + Rails 4.2.1 不会部署？

Question

我运行了 bundle update 并将 sprockets 更新为 3.0.0。

当我尝试通过 Capistrano 3 进行部署时，出现以下错误:

我四处寻找可能遇到相同问题的人，似乎没有任何问题或评论...

老实说，我什至不确定 sprockets、sprockets-rails 与 rails 有何关系。这让我很困惑......例如，默认的 Gemfile 带有一个新的 Rails 4.2.1 应用程序说 中允许 sprockets 3.0.0 Gemfile.lock，但是当你转到 sprockets 2->3 升级指南时，它显示 //= include 已被删除，但它就在 应用程序中.js 文件。

所以，也许我遗漏了什么，但我不太确定如何解决这个问题。

如果您使用的是 capistrano-rails，请尝试更新到 1.1.3。这为我解决了这个问题。

capistrano-rails CHANGELOG:

1.1.3 (Apr 18 2015)
- Fixed no_release behaviour (https://github.com/capistrano/rails/pull/95)
- Allow assets manifest backup with folder "manifests" (https://github.com/capistrano/rails/pull/92)
- Handle Sprocket 3 manifest filename
