问题描述
我使用的是python3和我自己编译的[Renderman][1]。
这个库使用了 boost_python，它通过 cpp 制作了 python 库。
test.py
import librenderman as rm
engine = rm.RenderEngine(44100,512,512)
$python test.py
JUCE v5.2.0
Traceback (most recent call last):
File "test.py",line 3,in <module>
engine = rm.RenderEngine(44100,512)
TypeError: __init__() should return None,not 'nonetype'
我搜索了一下，发现这是因为 python 2/3 差异。
然后检查链接库
$otool -L librenderman.so

我应该在哪里以及如何解决这个问题？？
虽然我熟悉python3，但不熟悉python2和boost-python
任何建议都有帮助。
