我有两个Docker镜像需要交叉编译：libs和devicemanager，其中devicemanager镜像依赖于libs镜像。
$ docker buildx build --platform linux/arm/v7 --rm --file ./Dockerfile --tag libs:latest --load ..字符串
但是，当我尝试使用
$ docker buildx build --platform linux/arm/v7 --rm --file ./Dockerfile --tag devicemanager:latest --load ..型
我得到以下错误：
[+] Building 0.5s (4/4) FINISHED

=> => transferring dockerfile: 2.18kB 0.0s

4 | # STAGE 2 - BUILD

ERROR: failed to solve: libs:latest: pull access denied, repository does not exist or may require authorization: server message: insufficient_scope: authorization failed型devicemanager的Dockerfile看起来像这样：
# STAGE 1 - Pre-built libs
FROM libs:latest as libs-dev
# ...型
值得注意的是，当我不尝试使用buildx交叉编译，而是使用标准的build命令为我的原生架构构建映像时，一切都很好。我想知道可能缺少什么，使得一切都可以使用build而不是buildx。
- 编辑1：* 回应BMitch的评论，这里是使用创建
libs:latestDocker镜像时的构建日志

我还可以看到，在运行docker images时，libs:latest已经成功构建。

我相信这是buildx构建器目前的一个局限性。我找到了https://github.com/moby/buildkit/issues/2343，它有很多讨论，但还没有解决方案。
