go mod 安装bee 报错

``` go get github.com/beego/bee go: finding github.com/derekparker/delve/service/rpccommon latest go: finding github.com/derekparker/delve/service latest go: finding github.com/derekparker/delve/terminal latest go: finding github.com/derekparker/delve/service/rpc2 latest go: github.com/derekparker/delve@v1.2.0: parsing go.mod: unexpected module path "github.com/go-delve/delve" go: error loading module requirements ``` 我使用go mod安装bee时报这个错误，但是我已经使用```go get github.com/go-delve/delve``` 请问是什么原因呢？
