使用 Capistrano 部署后，Rails（Puma 和Passenger）找不到捆绑的宝石

Question

我一直在阅读 PragProg Agile Rails 5 一书。我挂断了部署。我使用 Apache 在本地进行了直接复制/粘贴部署。然而，当我使用 Capistrano 部署时，部署完成且没有错误，但在当前发布目录中运行 passenger 或 rails s 立即失败，说它找不到 listen gem。有什么线索可以触发这个吗？

我跑过bundle package 和bundle --deployment。都没有帮助。我不确定 Capistrano 的目录应该是什么样子，但供应商/缓存 gem 不在当前目录中，即使它们在开发目录中。

这是我在production.log 中得到的。

当我访问http://localhost:8080 时，Apache 只是说“从应用程序收到不完整的响应”。我已经确保密钥设置正确。

我刚刚重新运行了场景，并且一切正常：
