无法在Windows上安装python lxml(和libxml2)

*****
Could not find function xmlCheckVersion in library libxml2. Is libxml2 installed?

我试图从这里(ftp://ftp.zlatkovic.com/libxml/)下载Windows的二进制文件并将它们添加到路径但它似乎没有帮助.

尝试使用以下错误日志安装时,手动下载lxml wheel(http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml for cp34)文件也会失败：

我在x64 win7机器上使用python34 32bit.
