Docker - 无法准备上下文：无法评估 Dockerfile 路径中的符号链接：GetFileAttributesEx

我今天刚刚下载了适用于 Windows 10 64 位的 Docker Toolbox。我正在浏览教程。我在尝试使用 Dockerfile 构建映像时收到以下错误。

Steps:

• 推出 Docker 快速入门终端。
• 创建后测试docker。
• 按照“构建您自己的映像”Web 链接中所述准备 Dockerfile
• 运行以下命令

docker build -t docker-whale .

Error: $ docker build -t docker-whale .

unable to prepare context: unable to evaluate symlinks in Dockerfile path: GetFileAttributesEx C:\Users\Villanueva\Test\testdocker\Dockerfile: The system cannot find the file specified.

BTW:我尝试了@提到的几个选项https://github.com/docker/docker/issues/14339 https://github.com/docker/docker/issues/14339

docker info

执行以下命令时，

检查 Dockerfile 是否存在于您当前的工作目录中。
