可能重复:
"WARN无法确定响应体的内容长度."是什么意思以及如何摆脱它？

我刚刚升级到rails 3.2.2,现在在rails s,页面加载,我在日志中得到所有这些错误:

[2012-03-07 19:46:14] WARN  Could not determine content-length of response body. Set content-length of the response or set Response#chunked = true
[2012-03-07 19:46:14] WARN  Could not determine content-length of response body. Set content-length of the response or set Response#chunked = true

根据以前的SO线程,我尝试了以下内容:

/config/application.rb

config.assets.logger = false
config.assets.logger = nil

这些都没有奏效.有关如何针对此错误禁用此日志记录的任何想法？或者解决问题:)

谢谢
