问题描述

我正在尝试使用 Linux 环境在 docker 容器中运行 Rscript。我有一个看起来像这样的 Dockerfile：

FROM arm32v7/ubuntu
ENV DEBIAN_FRONTEND=noninteractive
RUN apt-get update && apt-get install -y r-base

然后在与我运行的 Dockerfile 相同的文件夹中：

docker build -t armr .

这给了我以下消息：

我使用的是带有 Raspbian lite (buster) 的 RaspBerry Pi 3。

我清除了收到的可能会干扰的包，修剪了我的 docker 并使用 apt-transport-https 进行了尝试。

任何帮助，我对 docker（或 raspBerry 或 R）完全陌生。
