Rails Capistrano 生产部署运行错误的命令行导致错误 'invalid option --daemon'

Question

我一直在尝试修复这个错误，但我找不到解决方案。我正准备使用 nginx、puma 和 capistrano 将 Rails 应用程序部署到生产环境，但是当运行此命令行 bundle exec cap production deploy:initial 时我收到错误消息。在初始化 'PUMA:START' Top Task 后，我的终端立即抛出一条错误消息并退出进程。

shared/bundle/ruby/2.6.0/gems/puma-5.2.2/lib/puma/cli.rb:50:in `initialize': invalid option: --daemon (OptionParser::InvalidOption) puma stderr: Nothing written Tasks: TOP => puma:start (See full trace by running task with --trace)

我认为这是由之前执行的错误命令行引起的：

00:00 puma:start
      01 RBENV_ROOT=$HOME/.rbenv RBENV_VERSION=2.6.5 $HOME/.rbenv/bin/rbenv exec bundle exec puma -C /home/usr/myapp/shared/puma.rb --daemon

我试图通过修改部署过程命令来找到解决此问题的方法，但我没有找到任何相关的东西。

我将留下我的 Capfile、deploy.rb、nginx.conf 和 gems，这样您可能会更好地了解问题所在。

我怀疑您使用的 puma gem 版本（可能 > 5.0+）不支持 --daemon 选项。

这已在 capistrano-puma documentation 中突出显示。 puma cli 命令行解析器将抛出错误，因为 --daemon 不是受支持的选项之一。您可以检查 Gemfile.lock 的 puma 版本以验证这一点。

事实上，capistrano-puma 并不会阻止您使用高于 5.0 的版本 puma。但是，gem 用户负责插件兼容性要求。
