I'm trying to use rubber to deploy to my AWS EC2 for the first time. For testing im just using a t1.micro right now.
我第一次尝试使用rubber部署到AWS EC2上。测试im时，只使用t1。现在微。
I get a weird error with rubber after having edited rubber.yml after tcap rubber:create_staging
在编辑了橡胶之后，我发现了一个奇怪的错误。yml后tcap橡胶:create_staging

Any idea where to look for an error? It seems like a simple problem to me but I dont really have a clue where to look..
知道在哪里查找错误吗?这对我来说似乎是个简单的问题，但我真的不知道该往哪儿看。

Just remove rubber_env.
只是删除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(',')}"
There is this simple fix https://github.com/rubber/rubber/pull/406/files.
