在安装OpenCV期间创建虚拟环境时出现符号链接级别过多的错误？

Question

我一直在尝试使用以下安装指南安装OpenCV3:http://www.pyimagesearch.com/2015/06/15/install-opencv-3-0-and-python-2-7-on-osx/。尝试使用mkvirtualenv cv创建虚拟环境时出错。在

我用的是运行在约塞米蒂10.10.5的Mac电脑

给出的错误如下：

myuser=是im在我的笔记本中使用的用户的用户名

New python executable in /Users/myuser/.virtualenvs/cv/bin/python2.7
Traceback (most recent call last):

File "/usr/local/bin/virtualenv", line 11, in <module>

with open(dst, 'wb') as fdst:

IOError: [Errno 62] Too many levels of symbolic links: '/Users/myuser/.virtualenvs/cv/bin/python2.7'

我是python新手，我无法理解这个错误。有人能向我解释一下这个错误意味着什么，或者给我一个很好的解决方案吗。在

提前谢谢你！在
