為什么我不能為python安裝lxml？

Question

我已經下載了lxml的tarball，並正在使用ipython setup.py install嘗試安裝它。 不幸的是，它給了我很多錯誤消息：

src/lxml/lxml.etree.c:200651: error: ‘XML_XPATH_INVALID_OPERAND’ undeclared (first use in this function)

有人知道這是怎么回事嗎？ 顯然，cython會干擾安裝，但是我的系統上沒有安裝cython。 這是在centos 6.4操作系統上，ipython運行2.7。

lxml依賴於libxml2和libxslt 。 使用yum安裝開發頭文件：

yum install libxml2-devel libxslt-devel python-devel
