“go mod tidy”之错误“not a valid zip file”

执行 go mod tidy 时，遇到如下错误：

rpc imports
        github.com/zeromicro/go-zero/zrpc imports
        github.com/zeromicro/go-zero/zrpc/resolver imports
        github.com/zeromicro/go-zero/zrpc/resolver/internal imports

        k8s.io/kube-openapi/pkg/util/proto.test imports
        github.com/onsi/ginkgo/v2: zip: not a valid zip file

这个错误与 GOPROXY 的设置有关，当如下设置时就报上述错误：

GOPROXY="https://mirrors.aliyun.com/goproxy/,direct"

改为如下设置问题解决：

export GOPROXY="https://goproxy.cn,direct"
