推荐答案

tp_print 方法已从Python 3.9的API中删除.错误"'tp_print':不是'_typeobject''的成员；表示该代码适用于python< = 3.8.

The tp_print method was removed from the API in Python 3.9. Error "'tp_print': is not a member of '_typeobject'" means that the code is intended for Python <= 3.8.

降级到Python 3.8，然后重试.

Downgrade to Python 3.8 and try again.

更新. pyclipper 只是发布了1.2.1版，其中适用于Python 3.9的轮子.

Upd. pyclipper just released version 1.2.1 with wheels for Python 3.9.

PS.永远不要着急使用较新的主要Python版本，请等到所有第三方库都适应之后.

PS. Never hurry to a newer major version of Python, wait until all your 3rd-party libraries adapt.
