python-3.x - 无法在 Windows 7 上安装 ibm_db

Question

我在安装 ibm_db 时遇到问题。我收到“当该文件已存在时无法创建文件:'tests' -> 'test_2'”

我使用的是 Windows 7 x64，Python 3.6。目的是使用 SQLAlchemy 连接到 db2 数据库。我已经安装了 ibm-db-sa 数据库。

任何关于如何解决这个问题的想法都会很棒。

将评论转化为答案。

这是 Win7 上 ibm_db v2.0.8 的一个已知问题，由于已修复，您可以安装修复版本或以前的版本。此外，任何高于 v2.0.8 的 ibm_db 版本都将包含此修复。

2020 年 6 月 20 日:ibm_db v3.0.2 发布。

参见 github report

安装固定版本:

pip install "ibm-db==2.0.8a" (任何高于 2.0.8 的版本)

要安装以前的版本:

pip install "ibm-db<2.0.8"
