我使用下面的docker构建器交叉编译一个基于Alpine的docker映像：

Name:   builder_name
Driver: docker-container

Nodes:
Name:      builder_name0
Endpoint:  unix:///var/run/docker.sock
Status:    running
Buildkit:  v0.10.5
Platforms: linux/arm/v7*, linux/amd64*, linux/amd64/v2, linux/amd64/v3, linux/amd64/v4, linux/386

现在，运行命令时

$ docker buildx build --rm --platform linux/arm/v7 -t container_name:latest --file ./Dockerfile --load ..

运行时生成器无法安装redis-py

RUN pip3 install redis

以下是错误消息：

有人遇到过这样的问题吗？我尝试到处搜索uname -rs返回非零状态的情况，但什么都找不到。
