我已经为 JModelica（基于 python）安装了一个商业求解器包 (OCT) --> 当我想通过“Ipython”打开 JModelica 时，我收到以下错误消息：

Traceback (most recent call last):

  File "C:\OCT-1.0b1\Python27\scripts\ipython-script.py", line 5, in <module>

    from pkg_resources import load_entry_point

    path = sys.modules[parent].__path__

KeyError: 'pyomo'

我通过 spyder/Anaconda2（64 位）使用 pyomo

如果有人可以帮助我，那就太好了！

您可以将 pyomo 安装到 virtualenv 并避免与 JModelica 冲突：
