请帮助我.预先感谢.

推荐答案

lxml需要C/C ++库libxml，libxstl，因此您必须首先安装它.但是它们不是Python模块，而是标准库-可能是libxml.dll，libxstl.dll.

lxml needs C/C++ libraries libxml, libxstl so you have to install it first. But they are not Python modules but standard libraries - probably libxml.dll, libxstl.dll.

lxml可能还需要此库或C/C ++头文件* .h的源代码和C/C ++编译器来编译lxml

lxml may need also source code for this libraries or C/C++ header files *.h and C/C++ compiler to compile lxml

对于Windows，存在具有预编译模块的非官方Windows Python扩展包二进制文件还有lxml

For Windows exists Unofficial Windows Binaries for Python Extension Packages with precompiled modules and there is lxml

注意:这可能是一个重复的问题.您可以看到此 stackoverflow
