我一直在使用这个工具进行测试，以便从mongo db迁移数据，这个问题我还没有找到解决方案......一直在寻找解决方案......但是没有到目前为止解决方案。请在下面找到堆栈跟踪..
mosql版本未知（但是当我尝试卸载mosql时，它提到了mosql-0.4.3的版本 ruby版本：ruby 2.2.4p230（2015-12-16修订版53155）[x64-mingw32]
我在此文件夹C：\ Ruby22-x64 \ lib \ ruby \ gems \ 2.2.0 \ gems \ mosql-0.4.3 \ lib \ mosql下对cli.rb进行了更改，以删除第27行的“USR2”从列表中修复运行mosql的问题。

您可能希望将{sql_literal或#sql_literal_append方法添加到BSON::ObjectId，以便Sequel知道如何对其进行字面化。
