JModelica 中的 Python/Pyomo 错误

Question

我已经为 JModelica(基于 python)安装了商业求解器包 (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

  File "C:\OCT-1.0b1\Python27\lib\site-packages\pkg_resources.py", line 2825, in

 <module>

    add_activation_listener(lambda dist: dist.activate())

    callback(dist)

    add_activation_listener(lambda dist: dist.activate())

    map(declare_namespace, self._get_metadata('namespace_packages.txt'))

  File "C:\OCT-1.0b1\Python27\lib\site-packages\pkg_resources.py", line 1836, in

 declare_namespace

    path = sys.modules[parent].__path__

KeyError: 'pyomo'

我通过 spyder/Anaconda2(64 位)使用 pyomo

如果有人能帮助我，那就太好了!

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