Windows环境安装dmPython（WHL方式）

一、简介

dmPython 是 DM 提供的依据 Python DB API version 2.0 中 API 使用规定而开发的数据库访问接口。dmPython 实现这些 API，使 Python 应用程序能够对 DM 数据库进行访问。
dmPython 通过调用 DM DPI 接口完成 python 模块扩展。在其使用过程中，除 Python标准库以外，还需要 DPI 的运行环境。

二、使用场景

应用服务器与数据库服务器分开规划，且应用服务器上不安装数据库，这种情况下安装dmPython。可以编译成WHL包。window下相同版本的python环境可以直接导入不需在进行编译。

三、注意事项

• 建议数据库软件包中自带的dmPython源码包，减少摸不着头脑的错误。
• 编译安装时，它会探测数据库软件目录，最好提前设置好DM_HOME环境变量。

四、具体操作

1. 拷贝DB服务器相关文件

推荐使用随同数据库软件包下的相关文件以及驱动包，不推荐使用第三方渠道的下载包或其他数据库版本的目录文件以及驱动包

拷贝数据库安装目录的三类目录文件到应用服务器上

• 数据库服务器上$DM_HOME/drivers
• $DM_HOME/bin目录
• $DM_HOME/include目录

2. 添加环境变量

将如下四个路径，加入到PATH中

3. 编译whl包
