在 OSX 10.11.3 中安装 virtualenvwrapper 时出现问题

Question

我是编程和 python 的新手，但已经学习了几个月。我的目标是为 Python3.5.1 安装 openCV3。为此，我一直在关注本教程：http://www.pyimagesearch.com/2015/06/29/install-opencv-3-0-and-python-3-4-on-osx/

我的问题是我似乎无法正确安装 virtualenvwrapper。当我重新加载我的 .bash_profile 时，终端告诉我“bash：/usr/local/bin/virtualenvwrapper.sh：没有这样的文件或目录”。

在安装阶段，终端返回如下：

Gwenns-New-MBP:~ gwennlaine$ pip3 install virtualenvwrapper
Requirement already satisfied (use --upgrade to upgrade): virtualenvwrapper in ./Library/Python/2.7/lib/python/site-packages

    DEPRECATION: Uninstalling a distutils installed project (six) has been deprecated and will be removed in a future version. This is due to the fact that uninstalling a distutils project will only partially uninstall the project.

我应该注意我已经尝试了许多不同的这种/替代方法来安装它，并且已经在谷歌上花了两天时间研究这个问题，但似乎没有任何效果！

对我做错了什么有什么想法吗？

提前致谢！

所以，我厌倦了尝试实现这一目标，所以我选择了另一条路线。我安装了pyenv。然后我安装了 pyenv-virtualenv 和 pyenv-virtualenvwrappers 作为插件。这使我能够创建一个稳定且隔离的虚拟环境来安装和编译 OPenCV3。与普通的 virtualenv 相比，有些命令有所不同，但总体而言，它实现了相同的目标！

看起来您正在尝试通过 python 3 安装 virtualenvwrapper，但 osx 使用的是 python 2.7。你有没有安装python3？
