今天上服务器 更新一下 gem 发现 sprockets 3.7.0 死活升级不过
手动执行结果如下
gem install sprockets -V -v 3.7.0 --source=https://gems.ruby-china.org/
GET https://gems.ruby-china.org/specs.4.8.gz
302 Moved Temporarily
GET https://gems-ruby-china.b0.upaiyun.com/specs.4.8.gz
304 Not Modified
ERROR: Could not find a valid gem 'sprockets' (= 3.7.0) in any repository
GET https://gems.ruby-china.org/prerelease_specs.4.8.gz
302 Moved Temporarily
GET https://gems-ruby-china.b0.upaiyun.com/prerelease_specs.4.8.gz
304 Not Modified
然后检查 sprockets-3.7.0.gemspec.rz 结果正常
curl -I https://gems-ruby-china.b0.upaiyun.com/quick/Marshal.4.8/sprockets-3.7.0.gemspec.rz

发现 又拍云创建时间是 X-Upyun-Created-Date: Mon, 27 Jun 2016 09:11:27 GMT 过期时间是 Expires: Tue, 16 Aug 2016 20:20:22 GMT
那么这期间的更新就没有了 着时间跨度似乎有点太长了吧 
@huacnlee 看看 是不是得处理一下
更新一下 ruby.taobao.org 还能安装 XD
gem install sprockets -v 3.7.0 --source=https://ruby.taobao.org/
Successfully installed sprockets-3.7.0

谢谢提醒，之前只请求了 /specs.4.8 看没什么内容以为没东西，所以就缓存了。原来内容都在 /specs.4.8.gz 里面。
刚刚已经调整了一下配置，设置这个文件以及其他 *.4.8.gz 的文件缓存有效期 15 分钟。
