cannot load github.com/ugorji/go/codec: ambiguous import: found github.com/ugorji/go/codec in multip

本文详细记录了解决在Go项目中因重复导入github.com/ugorji/go/codec模块而导致的编译错误过程。通过设置正确的下载代理，避免包下载出现问题，并使用特定版本的依赖，最终成功解决了ambiguous import的问题。

cannot load github.com/ugorji/go/codec: ambiguous import: found github.com/ugorji/go/codec in multiple modules

执行go build时出现此提示

build mps/guid-service/guid-api: cannot load github.com/ugorji/go/codec: ambiguous import: found github.com/ugorji/go/codec in multiple modules:
        github.com/ugorji/go v1.1.4 (F:\Go Project\pkg\mod\github.com\ugorji\go@v1.1.4\codec)
        github.com/ugorji/go/codec v0.0.0-20181204163529-d75b2dcb6bc8 (F:\Go Project\pkg\mod\github.com\ugorji\go\codec@v0.0.0-20181204163529-d75b2dcb6bc8)

 网上说的那个replace的方法在我这里无效

// replace github.com/ugorji/go v1.1.4 => github.com/ugorji/go/codec v0.0.0-20181204163529-d75b2dcb6bc8


 解决办法：自己碰到的问题，解决有效

1.设置好下载代理，防止包下载有问题

确保代理生效后，执行下面命令

go get github.com/ugorji/go@v1.1.2

下载ok后再go build，问题解决
