in /Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/cv2/.dylibs/libavutil.56.31.100.dylib我尝试了以下方法来导入它，但似乎都不起作用
import opencv
import cv4
import cv3
import cv
import opencv-python
etc...如有任何帮助，将不胜感激，并提前向您表示感谢

我相信您正在使用masOS。
这是最新的Pillow 5.1.0版本中的一个错误。
这是由于为了构建双轮而将Xcode从版本8升级到9.2造成的。
El Capitan10.11是Xcode8的“最小运行macOS”。
Sierra 10.12.6是Xcode 9.2的最小版本。
https://en.wikipedia.org/wiki/Xcode#Xcode_7.0_-9.x(since_Free_On-Device_Development
将来会有一个Pillow 5.1.1版本来修复这个问题。
同时，解决方法是: pip install 'pillow!=5.1.0‘
(或者升级您的macOS，或者从源代码构建。)
有关更多信息，请参阅https://github.com/python-pillow/Pillow/issues/3068

您将显示一个pip list和一个堆栈跟踪，表明您正在使用Python3.8。除非MacOS上出了什么奇怪的问题，否则您将需要使用pip3 (而不是pip)来安装opencv-python。在那之后
import cv2应该行得通。

显然OpenCV 4.1.x不喜欢El Capitan ..。将OpenCV降级为3.4.5.20
在所需的环境中：
pip install --force-reinstall opencv-contrib-python==3.4.5.20否则：
sudo -H python3 -m pip install --force-reinstall opencv-contrib-python==3.4.5.20页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
