Golang Cloud功能和本地依赖项

Question

I am trying to deploy to google cloud using deploy command and my code refers local package using the github url. I getting below when deploying using gcloud deploy command. So in this example. My endpoints package refers to local package price using the full git url. What am I missing here ?

package endpoints

import (
    "encoding/json"
    "fmt"
    "github.com/piscean/pricing/price"
    "net/http"
)

func LawnPricing(w http.ResponseWriter, r *http.Request) {

    m, err := price.Pricing()

    c, err := json.Marshal(m)

    w.Write(c)
    r.Body.Close()
}

ERROR: (gcloud.functions.deploy) OperationError: code=3, message=Build failed: /tmp/sgb/gopath/src/serverlessapp/vendor/endpoints/pricing.go:6:2: cannot find package "github.com/piscean/pricing/price" in any of: /tmp/sgb/gopath/src/serverlessapp/vendor/github.com/piscean/pricing/price (vendor tree) /go/src/github.com/piscean/pricing/price (from $GOROOT) /tmp/sgb/gopath/src/github.com/piscean/pricing/price (from $GOPATH) /tmp/sgb/gopath/src/serverlessapp/vendor/endpoints/zipcode.go:5:2: cannot find package "github.com/piscean/pricing/zip" in any of: /tmp/sgb/gopath/src/serverlessapp/vendor/github.com/piscean/pricing/zip (vendor tree) /go/src/github.com/piscean/pricing/zip (from $GOROOT) /tmp/sgb/gopath/src/github.com/piscean/pricing/zip (from $GOPATH)

You should use the dependency package management tool for this called as dep.

Install dep by using the command:

go get -u github.com/golang/dep/cmd/dep

This would create the binary of dep in the GOBIN directory. Navigate to directory where main package is present and execute the command:

For Windows: %GOBIN%\dep.exe init

For Linux: $GOBIN\dep init

This would create Gopkg.toml and Gopkg.lock files along with the vendor folder that would solve your issue.
