python3 openCV安装报错: Symbol not found: _clock_gettime

Question

谁能帮我解决在 python3 中导入 opencv 时出现的错误？

当我在 python3 中导入 cv2 时，我得到类似的东西

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-
packages/cv2/__init__.py", line 4, in <module>
from .cv2 import *

ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/cv2/cv2.cpython-36m-darwin.so, 2):

此外，我使用的是 python 版本 3.6.3

如果不想升级操作系统，可以安装较早版本的opencv:

pip install opencv-python==3.3.0.10
