Ruby on rails ActiveStorage:：FileNotFoundError但该文件实际存在
我正在开发Rails 6.0.21应用程序（ruby 2.5.5），并使用puma 3.12.2作为开发web服务器和带有本地磁盘服务的ActiveStorage 我的应用程序不时会出现错误，并出现Ruby on rails ActiveStorage:：FileNotFoundError但该文件实际存在,ruby-on-rails,puma,rails-activestorage,Ruby On Rails,Puma,Rails Activestorage,我正在开发Rails 6.0.21应用程序（ruby 2.5.5），并使用puma 3.12.2作为开发web服务器和带有本地磁盘服务的ActiveStorage 我的应用程序不时会出现错误，并出现ActiveStorage:：FileNotFoundError。实际文件存在于磁盘上。模型正确响应。附件 重启puma解决了这个问题，之后它又会随机出现……有些天比其他天更频繁。 这在Apache上发生，mod_乘客也是这样 我做错什么了吗 稍后编辑：下面是我对puma、活动存储和错误的标准配置 A

# Puma can serve each request in a thread from an internal thread pool.
# The `threads` method setting takes two numbers: a minimum and maximum.
# Any libraries that use thread pools should be configured to match
# the maximum value specified for Puma. Default is set to 5 threads for minimum
# and maximum; this matches the default thread size of Active Record.

# Specifies the `port` that Puma will listen on to receive requests; default is 3000.
#
port ENV.fetch("PORT") { 3000 }
# Specifies the `environment` that Puma will run in.
#

# Specifies the `pidfile` that Puma will use.
pidfile ENV.fetch("PIDFILE") { "tmp/pids/server.pid" }
# Specifies the number of `workers` to boot in clustered mode.
# Workers are forked web server processes. If using threads and workers together
# the concurrency of the application would be max `threads` * `workers`.
# Workers do not work on JRuby or Windows (both of which do not support
# processes).
#
# workers ENV.fetch("WEB_CONCURRENCY") { 2 }
# Use the `preload_app!` method when specifying a `workers` number.
# This directive tells Puma to first boot the application and load code
# before forking the application. This takes advantage of Copy On Write
# process behavior so workers use less memory.
#
# preload_app!
# Allow puma to be restarted by `rails restart` command.
