1.建议先安装好Anaconda。
Scrapy第二(①)篇python环境之依赖管理器Anaconda(python3.9)_苍穹之跃的博客-
2.安装命令 (可能直接就安装成功了)
pip3 install opencv-python -i https://pypi.tuna.tsinghua.edu.cn/simple
3.如果有skbuild,cmake等依赖库报错,则先安装依赖。
pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple scikit-build
pip3 install -i https://pypi.tuna.tsinghua.edu.cn/simple cmake
4.再次安装即可
pip3 install opencv-python
pip3 install opencv-contrib-python -i https://pypi.tuna.tsinghua.edu.cn/simple
5.查看opencv-python版本
import cv2
if __name__ == '__main__':
version = cv2.__version__
print(version)
6.顺便把matplotlib也安装一下:
pip install matplotlib -i https://pypi.tuna.tsinghua.edu.cn/simple
