如何使用 python 安装 CPLEX？

Question

I am trying to install cplex for python 2.7.9. I downloaded IBM ILOG CPLEX Studio Preview 12.6.1 32bit and I tried to install it from Pycharm (using the GUI and the install package button) but I got this error message:

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.

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

Alternatively, I tried to install it from cmd.exe using python setup.py install and I got this output:

Please can anyone help me?

Answer 1

You might just want to set the path in your environment variables for python to tell that CPLEX is at this location. Like 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。
