python - 错误 : Could not build wheels for opencv-python which > use PEP 517 and cannot be installed directly

Question

嘿，
我有一个与此处显示的问题非常相似的问题 ERROR: Could not build wheels for scipy which use PEP 517 and cannot be installed directly .
我正在使用jetson Nano(ubuntu 18.04)。
错误

我试过这个来解决问题，但它没有帮助:

(heartkillayolotest2)christopher@ccz:~/heartkillayolotest2/heartkillayolotest2$pip3 install --upgrade pip Requirement already up-to-date: pip in./lib/python3.6/site-packages (20.2.3)

和

(heartkillayolotest2)christopher@ccz:~/heartkillayolotest2/heartkillayolotest2/yolo-v3$pip3 install --upgrade pip Requirement already up-to-date: pip in/home/christopher/heartkillayolotest2/heartkillayolotest2/lib/python3.6/site-packages(20.2.3)

不幸的是，错误仍然发生。
有人可以帮助我吗？

在尝试了此线程和其他线程中的大多数建议选项之后，包括最流行的:在安装 openCV 之前尝试“pip install --upgrade pip setuptools wheel”。
最终对我有用的是:

pip install --no-use-pep517 opencv-python
