如何修复在 Windows 上需要 'ibm_db' gem 的错误

Question

我是运行 Ruby 2.6.3p62 32 位 Windows 10 64 位。我使用 Ruby 安装程序安装了它。我成功安装了 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，解压缩并将环境变量 IBM_DB_HOME 设置到它的位置。另外，我在 PATH 变量中添加了 IBM_DB_HOME\bin。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 Github issues ibm_db gem 的页面，因为您的问题涉及配置而不涉及 [=24] =] 编程，或为 Db2 编程。

具体见：https://github.com/ibmdb/ruby-ibmdb/issues/83

看来 ibm_db gem 可能还不支持您 operating-system 平台上的 Ruby 版本，但它可能支持旧版本的 Ruby.
