Python - ibm_db 模块安装：“link.exe”失败，退出状态为 1120

Question

希望所有人都做得很好！我正在尝试将我的 DB2 与 python 连接，以便我可以通过 PyCharm 开发数据库事务。

我在我的机器上安装了 Python 3.6.1（32 位版本）。

而且，我正在尝试安装“ibm_db”模块以从 Python 执行 DB2 数据库相关事务，所以我运行了这个命令

我在我的机器上安装了 Visual Studio（Visual C++ 2015 构建工具），因为它是必需的，我得到了上述错误。

我的操作系统是：Windows 10 64bit

有人可以帮忙吗？

检查 DB2 SQLLIB 32/64 位， 我认为你需要像 python 这样的 32 位版本。
