cmake opencv3 with python2 on ubuntu get ImportError multiarray.so: undefined symbol: _Py_ZeroStruct

Question

我尝试使用 cmake-gui 在 ubuntu 上为 python2.7 构建 opencv3。我的 numpy(1.8.2) 是由 pip 安装的（实际上，我也尝试过 apt-get 但错误仍然存在）。每次我使用 cmake-gui 到 Configure 时，它都会抛出：

Error in sys.excepthook:
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/apport_python_hook.py", line 63, in apport_excepthook
    from apport.fileutils import likely_packaged, get_recent_crashes

    import apt_pkg
ImportError: /usr/lib/python2.7/dist-packages/apt_pkg.so: undefined symbol: _Py_ZeroStruct

Original exception was:
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/usr/local/lib/python2.7/dist-packages/numpy/__init__.py", line 153, in <module>

    from . import multiarray
ImportError: /usr/local/lib/python2.7/dist-packages/numpy/core/multiarray.so: undefined symbol: _Py_ZeroStruct**strong text**

_Py_ZeroStruct好像有问题。我已尝试重新安装 numpy，但没有成功。

我也试图忽略这个错误并保留 make && sudo make install 结果是我可以正确安装我的 OpenCV3 但我不能使用 python 的 cv2（没有名为 [ 的模块=24=]). 因此我认为这个错误是我必须解决的关键问题。

我想通了：

我应该确保 dist-package 或 site-package 路径中的 none 在 $PYTHONPATH

中
