似乎找不到它

推荐答案

您可以通过查看etree来获取版本:

You can get the version by looking at etree:

>>> from lxml import etree
>>> etree.LXML_VERSION
(3, 0, -198, 0)

其他感兴趣的版本可以是:etree.LIBXML_VERSION，etree.LIBXML_COMPILED_VERSION，etree.LIBXSLT_VERSION和etree.LIBXSLT_COMPILED_VERSION.

Other versions of interest can be: etree.LIBXML_VERSION, etree.LIBXML_COMPILED_VERSION, etree.LIBXSLT_VERSION and etree.LIBXSLT_COMPILED_VERSION.
