ruby-on-rails - unicorn 陷入循环 : Refreshing Gem list

Question

我正在使用 Rails 4.0.0、Ruby 2.3 和 Unicorn。

我的应用程序运行良好，直到我尝试在我的 Gemfile 中添加一个 Nem gem 的那一天。一切都在本地像魅力一样工作，但是当我使用 Capistrano 部署到 DO 时，我陷入了错误循环:

我不知道到底发生了什么，因为我可以在本地使用这个新 Gem 中的代码，但是在部署时它不会加载，也不会安装。

在谷歌上搜索似乎可能是语法问题，但不知道如何确定，因为很久以前我还没有添加 Gem，所以语法错误可能太老了。是否有一些工具可以检查是否存在语法错误？我觉得这很奇怪，因为它在本地工作。

类似的问题在这里。当您使用 unicorn:reload 更改 Gemfile 时会发生这种情况不会运行您的新代码。

解决了重新启动 unicorn 而不是重新加载它的问题。

如果您使用的是 Capistrano，请将部署后触发器从invoke 'unicorn:reload'到:

invoke 'unicorn:stop'
invoke 'unicorn:start'

根据 https://github.com/tablexi/capistrano3-unicorn/issues/45 unicorn:restart工作不正常。
