当我执行 bundle exec script/server -p3001 时，出现以下错误/stacktrace =(

我该如何解决这个问题？我的意思是，它指向的语法真的很奇怪……但这在 1.8.7 中有效 =\

最佳答案

检查语法，我遇到了类似的问题:

syntax error, unexpected '{', expecting ';' or '\n' (SyntaxError)
              def hash_for_{:create=>:post, :delete=>:pos...

我在 routes.rb 文件中为 :collection 键发送数组而不是散列。所以我有这个:

:collection => [ :next => :get, :prev => :get, :sort => :post ]

并更改为:

:collection => { :next => :get, :prev => :get, :sort => :post }

希望这有助于...
