我正在嘗試使用Go Buildpack在 Heroku 上放置一個 Go 應用程序，當它是基本的東西時這很好，但是一旦我做一個本地包，它就不會編譯。這是一個示例設置：結構+ship  +foo      foo.go  main.gomain.gopackage mainimport (  "os"  "fmt"  "net/http"  "ship/foo")func main() {  foo.Bar()  port := os.Getenv("PORT")  http.HandleFunc("/", root)  http.ListenAndServe(":" + port, nil)}func root(w http.ResponseWriter, r *http.Request) {  fmt.Fprint(w, "Aloha, world!")}foo.gopackage foofunc Bar() {}推git push heroku masterInitializing repository, done.Counting objects: 20, done.Delta compression using up to 8 threads.Compressing objects: 100% (13/13), done.Writing objects: 100% (20/20), 1.53 MiB | 586.00 KiB/s, done.Total 20 (delta 2), reused 0 (delta 0)-----> Fetching custom git buildpack... done-----> Go app detected-----> Installing go1.3.1... done-----> Running: godep go install -tags heroku ./...main.go:7:3: cannot find package "ship/foo" in any of:    /app/tmp/cache/go1.3.1/go/src/pkg/ship/foo (from $GOROOT)    /tmp/build_4b92e51c-3959-4ddb-8eff-90d72da70729/.heroku/g/src/_/Users/Daryl/Go/src/ship/Godeps/_workspace/src/ship/foo (from $GOPATH)    /tmp/build_4b92e51c-3959-4ddb-8eff-90d72da70729/.heroku/g/src/ship/foogodep: go exit status 1 !     Push rejected, failed to compile Go app知道這里發(fā)生了什么以及如何去做嗎？
