docker compose：错误：无法选择包

Question

我遵循了这个： https: //docs.docker.com/compose/gettingstarted/

并得到：

Step 5/10 : RUN apk add --no-cache gcc musl-dev linux-headers

The command '/bin/sh -c apk add --no-cache gcc musl-dev linux-headers' returned a non-zero code: 3

有什么建议么？

Answer 1

我刚刚遇到同样的错误。对我来说，问题是以前缓存的数据。所以，

docker-compose build --no-cache

解决了这个问题。我猜它试图通过使用实际上不存在的缓存图像来构建它。
