bash：bundle：即使安装了捆绑程序也找不到命令

Question

我正在AWS EC2实例上托管Rails应用，并通过Capistrano部署我的应用。在部署期间，我能够通过安装缺少的工具（如Monit）来解决错误。但是，我对此错误感到困惑：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时，终端会显示Could not locate Gemfile。我什至尝试重新安装捆绑程序gem install bundler，但仍然无法识别捆绑程序命令。我在下面列出了有关我的部署目标的详细信息。我不确定该怎么办，将不胜感激。

如果使用捆绑器，则应添加capistrano-bundler。参见GitHub issue
