我正在使用cygwin for python。我无法安装lxml，因为它显示一些库缺失错误。

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

有人可以帮忙吗？
您缺少libxml2的devel包
$ cygcheck -p libxml/xpath.h
Found 7 matches for libxml/xpath.h
libxml2-devel-2.9.3-1 - libxml2-devel: GNOME XML library (development) (installed binaries and support files)
libxml2-devel-2.9.4-1 - libxml2-devel: GNOME XML library (development) (installed binaries and support files)
libxml2-devel-2.9.4-2 - libxml2-devel: GNOME XML library (development)
...
安装libxml2-devel软件包的正确方法是使用cygwin安装程序
