找不到项目Gopkg.toml，请使用dep init初始化清单-在项目使用docker时从dep转到go模块

如何解决找不到项目Gopkg.toml，请使用dep init初始化清单-在项目使用docker时从dep转到go模块

当前正在尝试从dep迁移到go模块。

已经在我的项目源文件夹中运行了go mod vendor tidy，go build，一切似乎都很好。

但是，当我尝试通过运行docker-compose up启动项目时，会得到一个

could not find project Gopkg.toml,use dep init to initiate a manifest

我的Dockerfile是否缺少任何其他cmd？
