你打开提示，分步操作看看提示错误信息。这里信息太少了。 根据最后一行提示，应该是没有匹配的 /bin/sh 命令，是不是架构不对啊？要用 buildx 进行交叉编译

[pengyang1225]

执行docker buildx build --platform=linux/arm/v7 --build-arg OPENCV_VERSION=3.4.3 . -t debian10-python3-opencv3.4.3报错，我是本机要装交叉编译器吗？

[jiekechoo]

本机不需要任何交叉编译环境，镜像编译都是在 docker 容器里完成。自己编译实在不行，可以用 docker hub 里面的镜像包： 基础包：https://hub.docker.com/r/jiekechoo/debian10-python3-opencv3.4.3，自己再增加需要的包即可， 完整包：https://hub.docker.com/r/jiekechoo/rv1126-rknn_toolkit_lite1.7.1-ekuiper1.8.0
