如何解决找不到指定的模块 ibm_db.so
尝试执行 ruby 脚本时，我得到以下堆栈跟踪：
Traceback (most recent call last):

我们正在运行：
- ruby 2.6.6p146（2020-03-31 修订版 67876）[i386-mingw32]
- Rails 3.2.22.5
该脚本从 db2 数据库中提取一些数据，因此我安装了 ibm_db 32 驱动程序并确保 RUBY_DLL_PATH 指向 C:\Program Files (x86)\IBM\sqlLIB\clidriver\bin。此目录中应存在多少个文件，哪些文件应位于该目录中？我只有 IBMLDAPauthclient.dll，这看起来不对，但这就是这里安装的。欢迎和赞赏有关如何解决此问题的任何想法。提前致谢。
