在 Python 2.7 和 windows 7 机器（64 位）上。Shapely 模块 v. 1.2.16

该错误似乎与PyScripter IDE的使用有关。我在 Python shell 上尝试了以下代码，代码运行良好

from shapely.geometry import Polygon

p1 = Polygon([(0, 1), (1, 1), (1, 0), (0, 0), (0, 1)])
p2 = Polygon([(2, 4), (4, 4), (4, 2), (2, 2), (2, 4)])
p3 = Polygon([(0, 3), (3, 3), (3, 0), (0, 0), (0, 3)])


>>> p1.intersects(p2)
False
>>> p1.intersection(p2).area
0.0

>>> p1.intersects(p3)
True
>>> p3.intersection(p1).area
1.0

>>> p3.intersects(p2)
True
>>> p3.intersection(p2).area
