如何使用 python 安装 CPLEX？

Question

我正在尝试为 python 2.7.9 安装 cplex。 我下载了 IBM ILOG CPLEX Studio Preview 12.6.1 32bit 并尝试从 Pycharm 安装它（使用 GUI 和安装包按钮），但我收到以下错误消息：

Figuring out CPlex setup.


Targeting 32bit platform.

Traceback (most recent call last):

  File "<string>", line 17, in <module>

  File "C:\Users\me\AppData\Local\Temp\pycharm-packaging0.tmp\pycpx\setup.py", line 148, in <module>

    "concert include directory", 'and', '', False)

  File "C:\Users\me\AppData\Local\Temp\pycharm-packaging0.tmp\pycpx\setup.py", line 145, in find_path

    % (name, (', '.join(goal_list))))

Exception: CPLEX concert include directory not found: please set environment variable CPLEX_PATH to point to the base of the CPlex/Concert installation. Attempting to find files: ilconcert/iloexpression.h, ilconcert/iloalg.h, ilconcert/iloenv.h, ilconcert/ilosolution.h.

Cleaning up...
Command python setup.py egg_info failed with error code 1 in C:\Users\me\AppData\Local\Temp\pycharm-packaging0.tmp\pycpx
Storing debug log for failure in C:\Users\me\pip\pip.log

或者，我尝试使用python setup.py install从cmd.exe安装它，我得到了这个输出：

请任何人都可以帮助我吗？

Answer 1

您可能只想在环境变量中为 python 设置路径，以告诉 CPLEX 位于此位置。 像 CPLEXhome/python/PLATFORM/。

Answer 2

您可能希望将 /cplex 目录从 IBM 安装路径复制到本地 python 模块路径。
