THREE version R141. Which CSG library to use is appropriate?

I plan to perform mesh operations, using THREE-CSGMesh, the console prompts me "export ‘Face3’ (imported as ‘THREE’) was not found in ‘three’

I think I found it,

Try @gkjohnson’s GitHub - gkjohnson/three-bvh-csg: A flexible, memory compact, fast and dynamic CSG implementation on top of three-mesh-bvh

thanks! I’ll try :smiling_face_with_three_hearts:

Going back today I ran the example from GitHub - manthrax/THREE-CSGMesh: Conversion of a CSG library for use with modern THREE.js again. And carefully looked at the source code, it is compatible. source lines 111 - 201, before I introduced the vue project and rashly posted it, sorry.
