Question

我是capistrano和ruby的新手，使用cap deploy时遇到一些错误。我试图升级我的ruby版本和io-console，但是它们都没有帮助我解决问题。有人可以帮我解决吗？

在我的错误日志下面：

错误消息的路径看起来像您正在使用2.0 gem的Ruby 1.6.0和版本i18n。 i18n gem在该版本中使用弯曲的Heredoc语法（<<~）。语法是在Ruby 2.3中引入的。

这意味着您有两个选择：

将您的Ruby版本至少更新为2.3 或
降级i18n。 1.5.1似乎是不依赖Ruby 2.3的最新版本

部署capistrano时为什么会出现语法错误？
