报错是因为go代理的问题
ChainMaker 的 Go 依赖（如 chainmaker.org/chainmaker/common/v2）通常需要从 ChainMaker 的私有 Go 代理 下载，而不是 proxy.golang.org。运行以下命令检查当前代理设置：
 

go env | grep GOPROXY

如果输出是：

GOPROXY=https://proxy.golang.org,direct

需要修改为 ChainMaker 的代理（如 https://goproxy.io 或公司内部代理）：

go env -w GOPROXY="https://goproxy.cn,direct"
