sidekiq突然停止工作

Question

我正在使用sidekiq在Rails应用程序中运行后台进程。
从昨天开始，它运行良好，但是现在，当我尝试在命令行界面中使用sidekiq运行它时，

我确实在端口6379中运行了Redis redis-server 。
我尝试了gem update ，但是它什么也没改变。
删除gem bigdecimal会摆脱already initialized警告，但是undefined method错误仍然存​​在，并导致sidekiq崩溃。
谷歌搜索它并没有从我一天的研究中发现有用的结果。
提前致谢。

我建议采取以下步骤：

• 删除当前版本的ruby以及所有依赖它的库，gem和文件。

• 通过RVM安装ruby。 在RPi上进行编译需要花费一生的时间，但可能有助于避免BigDecimal错误。

• 在您的项目中，请根据GitHub上的问题181 require 'grape' ， 可能会有助于解决add_builtin_type错误。

我无法在Π上重现错误。
