Go project with third party packages on Heroku

问题

When deploying a Go project to Heroku, installation of the pq package fails. I've posted this in heroku buildpack github issues as well.

Error at deploy time:

-----> Running: godep go install -tags heroku ./...
gournay.go:10:3: cannot find package "github.com/lib/pq" in any of:
    /app/tmp/cache/go1.2.1/go/src/pkg/github.com/lib/pq (from $GOROOT)
    /tmp/build_ce268203-801e-4dfc-a56c-d70698d6c5bf/.heroku/g/src/github.com/andyatkinson/gournay/Godeps/_workspace/src/github.com/lib/pq (from $GOPATH)
    /tmp/build_ce268203-801e-4dfc-a56c-d70698d6c5bf/.heroku/g/src/github.com/lib/pq
godep: go exit status 1

go get and go install run locally as expected. The project is built and running locally. I believe my package structure is correct, and GOPATH and GOROOT are correct. I am using godep which creates the dependencies file below. The source for the pq package appears to be copied into the project, so it seems like it would compile from that source.

~/go/src/github.com/andyatkinson/gournay (master) $ cat Godeps/Godeps.json
{
    "ImportPath": "github.com/andyatkinson/gournay",
    "GoVersion": "go1.2.1",
    "Deps": [
        {
            "ImportPath": "github.com/lib/pq",
            "Rev": "c808a1bb644594ca717ac61f71e6b0e454b835e2"
        }
    ]
}

Am I missing something? Anything else I should check? Thanks!

回答1:

Do you run godep save on development?

from godep README:

$ godep save
This will save a list of dependencies to the file Godeps/Godeps.json, 
and copy their source code into Godeps/_workspace. Read over its 
contents and make sure it looks reasonable. 
Then commit the file to version control.

--- UPDATE ---

I see your repo, and up on heroku http://warm-depths-3154.herokuapp.com/, follow the steps

rm -Rf  gopack.config .godir .gopack
godep save
git add --all . // please commit the Godep folder
git commit -m 'using godep, removed gopack'
