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 并重试.

Downgrade to Python 3.8 and try again.

更新.pyclipper 只是发布版本 1.2.1 带轮子适用于 Python 3.9.

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

附注.不要急于使用更新的 Python 主要版本，等到所有 3rd 方库都适应后再使用.

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