我第一次尝试使用橡胶部署到我的 AWS EC2。为了测试我现在只使用 t1.micro。

在 tcap Rubber:create_staging 之后编辑了 Rubber.yml 后，我得到了一个奇怪的橡胶错误

这是消息：

知道在哪里查找错误吗？这对我来说似乎是一个简单的问题，但我真的不知道在哪里看..

最好的，米

只需删除Rubber_env。

staging_roles: "#{known_roles.reject {|r| r =~ /slave/ || r =~ /^db$/ }.join(',')}"
# instead of
staging_roles: "#{rubber_env.known_roles.reject {|r| r =~ /slave/ || r =~ /^db$/ }.join(',')}"

有这个简单的修复https://github.com/rubber/rubber/pull/406/files。
