ruby-on-rails - Rails 应用程序无法在本地机器上的生产环境中运行

问题描述

在开发环境中它工作正常，但是当我在生产环境中运行应用程序时，它说我们很抱歉，但是出了点问题。如果您是应用程序所有者，请查看日志以获取更多信息。

生产日志说：

解决方案

我猜问题出在production.rb配置文件中：您应该允许 Puma 提供静态文件。

在生产服务器中，静态文件通常由 Nginx 提供，但如果您在本地计算机上运行 Puma，情况并非如此。

为此，请production.rb将此值设置为 true（或创建一个ENV名为 的变量RAILS_SERVE_STATIC_FILES）：

config.public_file_server.enabled = true
