【问题描述】：
我正在尝试在生产环境中从https://github.com/rails/web-console 运行 rails web-console。我知道有人警告不要这样做，但我打算使用它的应用程序是内部的，无法在生产环境中访问。
我使用的配置：
config.web_console.development_only = false
config.web_console.whitelisted_ips = %w(<IPs that should have permission>)
所以控制台最终在开发和测试中完美运行，但在生产中失败并出现非常奇怪的错误。

我可以修改 gem 以使其工作吗？或者有什么解决方法？
红宝石：v2.3.1 导轨：v4.2.1 网络控制台：v3.3.0
谢谢
更新：
我找到了解决问题的方法。它与 gem 如何处理日志记录有关。我仍然不确定为什么它在开发中有效，但在生产中无效。这是我为使其工作所做的工作
我将以下代码添加到 config/initializers/web_console.rb
WebConsole::View.class_eval do
def render(*)
super
end
end
基本上，我已经覆盖了位于 https://github.com/rails/web-console/commit/4ba9f5044f9322ea16f97e69b7167170c9c34522 的 render(*) 方法
感谢大家的帮助
