ruby-on-rails - bash：bundle：即使安装了捆绑器，也找不到命令

问题描述

我在 AWS EC2 实例上托管一个 Rails 应用程序，并使用 Capistrano 部署我的应用程序。在部署期间，我已经能够通过安装缺少的工具（如 Monit）来解决错误。但是，我被这个错误难住了：puma stderr: bash: bundle: command not found. 我看到捆绑器已安装在服务器上，但是当我键入bundle终端时显示Could not locate Gemfile. 我什至尝试过重新安装 bundler gem install bundler，但仍然无法识别 bundle 命令。我在下面列出了有关我的部署目标的详细信息。我不知道该怎么做，如果有任何帮助，我将不胜感激。

解决方案

似乎某些 puma 设置已被覆盖。我将以下行添加到deploy.rb:set :rbenv_map_bins, %w{rake gem bundle ruby rails puma pumactl}以克服此错误。
