Capistrano 失败 - 没有当前目录/捆绑：未找到/回滚

Question

最近我将我的一个 Rails 应用程序移到了一个新配置的 EC2 ubuntu 实例。运行与旧服务器相同的 ruby​​ 版本，带有乘客的 apache。但是我仍然无法使用Capistrano 将应用程序部署到服务器。我仍然不知道该错误，所以我将我的部署日志粘贴在这里。这也是我的Capistrano recipe。感谢有人可以在这里找到问题。

Answer 1

简而言之，似乎在服务器上找不到 bundle 命令。

您可以通过 SSH 以“ubuntu”（部署文件中指定的用户）身份将其安装到服务器并尝试运行bundle。如果您收到 command not found 错误，则可能未安装 bundler 或 'ubuntu' 用户没有权限。

如果上述命令确实有效，那么当 cap 尝试执行其命令时，您的环境变量可能不会被加载。我必须在部署脚本中指定以下环境变量：

default_environment['PATH'] = '/usr/local/lib/ruby/gems/1.9.1/bin:$PATH'
default_environment['GEM_PATH']= '/usr/local/lib/ruby/gems/1.9.1'

显然，调整路径以适合您的服务器配置。

我希望这会有所帮助！
