Ruby 之前没有插入这样的中间件：ActionDispatch:：Static（RuntimeError），仅在使用Nginx时插入

我正在尝试在docker容器中与乘客一起使用nginx。 如果我使用passenger standalone启动rails应用程序，它将正常工作：

bundle exec passenger start --engine=builtin --max-pool-size=6 --min-instances=3

但是，如果我尝试将nginx用于同一个rails应用程序，则会出现以下错误：

移除宝石

这是因为在actionDispatch:Static之前调用了font\u中间件

还请注意，fon_assets gem仅在资产未在生产中预编译的情况下才起作用。参考。如果使用nginx预编译和提供资产，请参考配置删除gem

config.service\u static\u文件的值是多少？您能否运行“bundle exec rake middleware”和“RAILS_ENV=production bundle exec rake middleware.”。通常情况下，使用ActionDispatch:：Static

config.service\u Static\u files

值为true，

bundle-exec-rake中间件

和

RAILS\u ENV=production bundle-exec-rake中间件

都在工作。能否列出带生产和不带生产的bundle-exec中间件。同时尝试禁用服务静态文件请检查上面的编辑，我已将

config.serve\u-static\u文件

设置为false，还是一样的问题config.service\u static\u文件的值是多少？您能否运行“bundle exec rake middleware”和“RAILS_ENV=production bundle exec rake middleware.”。通常情况下，使用ActionDispatch:：Static
