如何修复Windows上需要'ibm_db'gem的错误

Question

我在Windows 10 64位上运行Ruby 2.6.3p62 32位。 我使用Ruby Installer安装了它。 我已成功安装gem'ibm_db'，没有任何错误。 我从http://public.dhe.ibm.com/ibmdl/export/pub/software/data/db2/drivers/odbc_cli/nt32_odbc_cli.zip下载了DB2-clidriver，将其解压缩并将环境变量IBM_DB_HOME设置为其位置。 。 另外，我将IBM_DB_HOME \\ bin添加到PATH变量中。 当需要ibm_db时，出现以下错误：

C:\Users\myuser\Programs\Ruby26\bin>ruby -e "require 'ibm_db'"

最后一行提到的文件

C:/Users/myuser/Programs/Ruby26/lib/ruby/gems/2.6.0/gems/ibm_db-4.0.0-x86-mingw32/lib/mswin32/rb2x/i386/ibm_db.so

确实存在。

您的问题可能更适合ibm_db gem的Github 问题页面，因为您的问题与配置有关，与Ruby编程或Db2编程无关。

特别请参阅： https : //github.com/ibmdb/ruby-ibmdb/issues/83

看来ibm_db gem可能尚未在您的操作系统平台上支持您的Ruby版本，但是它可能支持较旧的Ruby版本。
