未定义的方法“关闭！” 对于nil：NilClass

Question

I'm getting a really weird error with rails. It happens periodically every so often (and it seems to be when I wake up my computer after a long while)

undefined method `close!' for nil:NilClass
 (in /usr/local/rvm/gems/ruby-2.0.0-p247/gems/turbolinks-1.3.0/lib/assets/javascripts/turbolinks.js.coffee)

Eventually it will fix itself. It doesn't fix if I restart the server and it happens with different coffeescript files constantly. In the case above, it is turbolinks. However before I restarted the server and refreshed a few times it was history.js.coffee - What is going on here?

EDIT: Now after restarting it works magically. Obviously it's not a problem now but it's happening at random points and it is slowing down my workflow. It sounds like a permissions problem but they all seem correct.q

Answer 1

This is most likely because the CoffeeScript cannot be compiled on the fly.

In production check things like enough disk space and enough available memory.
