我最近丢失了我的硬盘，目前正在重建我的笔记本电脑（运行 Mountain Lion）开发系统。今天下午我去安装virtualenvwrapper，遇到了一些奇怪的事情，阻止我安装virtualenvwrapper。
我做了以下事情：
- 已安装设置工具。
- 使用 easy_install-2.7 安装 pip。
- 使用 pip-2.7 安装虚拟环境。
当我使用 pip-2.7 安装 virtualenvwrapper 时，我得到以下信息（见下文）。-2.5,-2.6,-2.7后缀对山狮来说似乎是新事物？我已经尝试过没有后缀的相同过程，但这也不起作用。
我之所以发帖，是因为我怀疑这里有些地方出了问题，并且想在它成为一个更隐蔽的问题之前深入了解它。
下载并安装 2.7 的新版本并设置我的路径以使用它对我来说更好吗？
