python-3.x - 安装python-flask会显示错误[python setup.py egg_info失败，错误代码为1]

Question

我是python框架“ flask”的初学者，我遵循此link进行安装和演示App（创建虚拟环境）。

我在Windows平台上使用python 3.3.2

 python virtualenv.py flask

上面的命令执行得很好，所有文件都正确下载，但是当我执行时

 pip install flask==0.9

它给我以下错误

 Downloading/unpacking flask==0.9

请指导我正确安装

您有任何理由要专门安装0.9版吗？为什么不使用pip install flask，它将为Python 3.3.x安装最新的0.10.1及其依赖项？我尝试了一下，在virtualenv中运行良好，而安装0.9版给了我与您相同的错误。
