macosx的opencv教程

我试图按照本教程安装opencv，但找不到~/.profile目录。它说我没有许可，当我进入它时，它说它找不到它，但当我看到它时。我不知道怎么找到它

当我尝试执行houghline时

 File "houghlines.py", line 10, in <module>
    from ctypes_opencv.cv import *
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/ctypes_opencv/__init__.py", line 18, in <module>
    from ctypes_opencv.cxcore import *
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/ctypes_opencv/cxcore.py", line 80, in <module>
    _cxDLL, _cvDLL, _hgDLL = detect_opencv()    
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/ctypes_opencv/cxcore.py", line 58, in detect_opencv
    cxDLL = cdll.LoadLibrary(find_lib('cxcore'))
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/ctypes_opencv/cxcore.py", line 54, in find_lib
    raise ImportError("OpenCV's shared library '%s' is not found. Make sure you have its path included in your PATH variable." % name)
ImportError: OpenCV's shared library 'cxcore' is not found. Make sure you have its path included in your PATH variable.

ImportError:找不到OpenCV的共享库“cxcore”。确保path变量中包含其路径。

可能不存在~/.profile“目录”。这是一个文件，您需要在用户目录中创建它
