尝试使用 easy_install 为 Python 2.7 安装 caldav。lxml 失败了，我找到了它的二进制安装程序，适用于除 2.7 之外的所有 Python 版本。
使用 easy_install 我得到以下信息：
Running lxml-2.3.4\setup.py -q bdist_egg --dist-dir c:\users\jimste~1\appdata\lo
cal\temp\easy_install-vhvbst\lxml-2.3.4\egg-dist-tmp-qs4ol2

lxml 如果失败。知道如何在 Windows 上为 Python 2.7 安装它吗？
