之前没有要插入的中间件：ActionDispatch::Static (RuntimeError) 仅在使用 Nginx 时
No such middleware to insert before: ActionDispatch::Static (RuntimeError) ONLY when using Nginx
我正在尝试在 docker 容器中将 nginx 与 passenger 一起使用。
如果我使用乘客独立启动 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，我会收到此错误：

删除 font_assets gem.
发生这种情况是因为 font_assets RackMiddleWare 在 ActionDisptach:Static 之前被调用。
另请注意，fon_assets gem 仅在资产未在生产中预编译时才有效。参考https://github.com/ericallam/font_assets#important .If assets are precompiled and served using nginx refer nginx 配置
@tessie 的回复可能是最好的。您可以删除 gem 并使用 rack-cors gem 或仅插入 headers 例如
config.public_file_server.headers = {
'Cache-Control' => "public, max-age=#{(config.assets.digest ? 1.year : 1.minute).to_i}",
'Access-Control-Allow-Origin' => '*',
'Access-Control-Allow-Headers' => 'x-requested-with',
'Access-Control-Allow-Methods' => 'GET',
'Access-Control-Max-Age' => '3628800',
}
