最近，我试图在Mac中安装pcl-python。 （github：https://github.com/strawlab/python-pcl）我在setup.py文件中找到注释，并更改了一些代码以适合Mac。
from Cython.Distutils import build_ext
line 570:ext_args['extra_compile_args'].append(["-stdlib=libstdc++"])
line 587:ext_args['extra_link_args'].append(["-stdlib=libc++"])
但是，当我在终端中输入python setup.py install时，发生了其他错误。这是我终端的输出
