No such file or directory @ rb_sysopen - tmp/pids/puma.pid
我正在尝试启动 puma，但在最后一步失败，如下所示：

无法在其他地方找到解决方案，它们都与不同的事物有关。
可以解决手动创建必要的文件夹，然后服务器进程可以创建pid文件。
mkdir -p tmp/pids
您可以在 config/puma.rb 中添加：
require "fileutils"
FileUtils.mkdir_p("tmp/pids")
当我第一次通过 rails app:update 添加 puma.rb 文件到 Heroku 应用程序的 rails 5.2 时发生此错误。
# Specifies the `pidfile` that Puma will use.
pidfile ENV.fetch("PIDFILE") { "tmp/pids/server.pid" }
通过添加 tmp/pids/.keep 文件解决，
$ touch tmp/pids/.keep
并更新 .gitignore 文件如下。
# Ignore all logfiles and tempfiles.
/log/*
/tmp/*
!/log/.keep
!/tmp/.keep
# Ignore pidfiles, but keep the directory.
/tmp/pids/*
!/tmp/pids/
!/tmp/pids/.keep
