部署到Elastic Beanstalk时如何安装Go依赖项？

Question

I have an application that's split across a few different files and I'm having trouble deploying it. I've followed this documentation, but I'm getting the following:

application.go:7:5: cannot find package "github.com/gorilla/handlers" in any of:

I assume I need to install the libraries I'm using in the $GOPATH as part of the deployment process, but I don't know how to do that and haven't found any examples of it. Using the Procfile seems promising, but all of my searches keep leading me to Heroku resources.

You could use a vendoring tool to store all your dependencies within a vendor folder.

I use govendor.

Steps:
 1. go get -u github.com/kardianos/govendor
 2. cd $GOPATH/yourProject
 3. govendor init
 4. govendor add +external

Now the directory 'yourProject' can be build independently on any machine provided it is in $GOPATH.

Note : Requires Go 1.6+ or 1.5 with GO15VENDOREXPERIMENT=1.

Edit : As per fl0cke's comment. If Elastic Beanstalk only supports Go 1.4, the possible options are :

• Cross compile a binary and deploy it to Elastic Beanstalk.
• Create a custom AMI with Go 1.6+ installed..
• Create a Docker Image Image as per fl0cke's answer.
