我在尝试使用Go模块在Go 1.11中部署Google云功能时遇到问题。我的代码结构如下GOPATH：

└── example
    ├── models
    │   ├── go.mod
    │   └── models.go
    └── load
        ├── fn.go
        ├── go.mod
        ├── go.sum
        └── vendor
            └── ....

load / go.mod如下所示：

module github.com/example/load

require (
    github.com/example/models v0.0.0
)

replace github.com/example/models => ../models

当我尝试使用命令部署功能时

gcloud functions deploy load-data --entry-point GCSNewFileTrigger --runtime go111 --trigger-resource new_data --trigger-event google.storage.object.finalize

我收到以下错误：

Deploying function (may take a while - up to 2 minutes)...failed.                                                                                                                                                                     
ERROR: (gcloud.functions.deploy) OperationError: code=3, message=Build failed: go: parsing /models/go.mod: open /models/go.mod: no such file or directory
go: error loading module requirements

命令go mod vendor并go mod verify在本地成功运行，我可以models在load
