我正在尝试在Mac上安装OpenCV-python,并且使用了以下内容:
$ pip安装opencv-python
这给了我以下错误:
$pip install opencv-python
Collecting opencv-python

matplotlib 1.3.1 requires nose, which is not installed.
matplotlib 1.3.1 requires tornado, which is not installed.
Installing collected packages: numpy, opencv-python
Found existing installation: numpy 1.8.0rc1
Cannot uninstall 'numpy'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
然后我确实尝试了
pip install --upgrade matplotlib
,它没有改变任何东西。它只是告诉我:matplotlib 2.2.2 requires backports.functools-lru-cache, which is not installed.
matplotlib 2.2.2 has requirement numpy>=1.7.1, but you'll have numpy 1.8.0rc1 which is incompatible.
当我发现有很多方法可以在互联网上安装openCV-python时,例如:
https://www.pyimagesearch.com/2015/06/15/install-opencv-3-0-and-python-2-7-on-osx/
并且我在其他Mac上安装了代码,但是在代码中出现了很多导入cv2问题。
如果有人有很好的解决方案或推荐来安装openCV-python,我将非常高兴。
谢谢
最佳答案
总而言之,macOS预先安装了Python,因此您不应该对已安装的软件包感到困惑,因为某些系统实用程序依赖于它们。
https://docs.python.org/3.7/using/mac.html
您应该看看venv或virtualenv。
您可以阅读以下答案:https://stackoverflow.com/a/41972262/4796844,它将使您掌握基础知识。
简而言之,要解决您的问题:
$ python3 -m venv ./project-name
$ . ./project-name/bin/activate
$ pip install opencv-python
离开虚拟环境,只需:
$ deactivate
