python - 将 lxml 安装到 virtualenv

Question

我正在尝试在 Windows 7 上使用 Python3.4 在 vi​​rtualenv 中安装最新的 lxml 模块。作为 Linux 的长期用户，这个过程应该很简单，但当然不是。我正在尝试安装最新的 lxml，目前没有适用于 Python3.4+ 的软件包因​​此，我获得了 libxml2 和 libxslt，但似乎无法识别它们。谁能指出我将所有内容链接在一起的正确方向。

我已经厌倦了 http://lxml.de/build.html 中的几乎所有内容以及我能想到的所有变体。任何帮助将不胜感激。

错误日志如下:

Answer 1

我从 Christoph's Gohlke's Python page 下载了 lxml-3.4.4-cp34-none-win_amd64.whl并使用

安装它

pip install lxml-3.4.4-cp34-none-win_amd64.whl 

它对我有用。
