如何使用 python 安裝 CPLEX？

Question

我正在嘗試為 python 2.7.9 安裝 cplex。 我下載了 IBM ILOG CPLEX Studio Preview 12.6.1 32bit 並嘗試從 Pycharm 安裝它（使用 GUI 和安裝包按鈕），但我收到以下錯誤消息：

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.

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，我嘗試使用python setup.py install從cmd.exe安裝它，我得到了這個輸出：

請任何人都可以幫助我嗎？

Answer 1

您可能只想在環境變量中為 python 設置路徑，以告訴 CPLEX 位於此位置。 像 CPLEXhome/python/PLATFORM/。

Answer 2

您可能希望將 /cplex 目錄從 IBM 安裝路徑復制到本地 python 模塊路徑。
