The auhor discusses the imports within his own dapp application.

The imports are completely outdated and do not work.

import (
“net/http”
“github.com/julienschmidt/httprouter”
“github.com/jbenet/go-ipfs/core”
“path”
“html/template”
“fmt”
“log”
“github.com/go-kerala/kerala”
peer “github.com/jbenet/go-ipfs/p2p/peer”
)

The repository github.com/jbenet/go-ipfs no longs exists and is now github.com/ipfs/go-ipfs.

The import github.com/jbenet/go-ipfs/p2p/peer is no longer valid. Even if we substitute github.com/jbenet/go-ipfs for github.com/ipfs/go-ipfs

Note from the Author or Editor:
The imports with the word 'ipfs' in them in that list should be removed and replaced with a single import:

https://github.com/ipfs/go-ipfs/

and the import “github.com/go-kerala/kerala” should be changed to:

https://github.com/llSourcell/kerala

The author instructs the reader to install a required dependency with the command:

go get -u github.com/llSourcell/go-kerala/kerala

Not only does this command not work but the repository does not exist.

Note from the Author or Editor:
The correct command is:

go get -u https://github.com/llSourcell/kerala
