Windows10上的docker图像构建“上下文取消”错误

我正在尝试构建一个简单的 r-base 官方 docker 映像，但它在 Windows 10 上给了我一个奇怪的“上下文取消”错误。

我试过拉图像（成功）然后构建它，但我遇到了同样的错误。我也试过重新安装 docker 或从 Docker Hub 构建任何其他映像（R 与否），但我也没有运气。奇怪的是，当我重新安装 docker 时，它在 shell 上运行了入门教程而没有问题。

可能会发生什么？

这是我的 dockerfile

FROM r-base:4.0.2
COPY . /usr/local/src/myscripts
WORKDIR /usr/local/src/myscripts
CMD ["Rscript", "main.R"]

和外壳输出
