sidekiq 突然停止工作
sidekiq suddenly stops working
我在 rails 应用程序中使用 sidekiq 到 运行 后台进程。
从昨天开始它运行良好，但现在当我尝试在命令行界面中使用 sidekiq 运行 它时，我得到

我在 6379 端口有 redis-server 运行ning。
我试过 gem update，但没有任何改变。
删除 gem bigdecimal 会消除 already initialized 警告，但 undefined method 错误仍然存在并导致 sidekiq 崩溃。
我在一天的研究中用谷歌搜索没有得到有用的结果。
提前致谢。

我建议采取以下步骤：
删除 ruby 的当前版本以及依赖它的所有库、gem 和文件。
通过 RVM 安装 ruby。在 RPi 上编译需要一生，但 可能 有助于避免 BigDecimal 错误。
在您的项目 require 'grape' 中，根据 issue #181 on GitHub， 可能 有助于解决 add_builtin_type 错误。
我无法在我的 Π 上重现错误。
