golang错误：运行go get时找不到目录包

Question

I'm trying to solve the example provided in Orielly book Decentrallized Applications.

The go-ipfs package seems to be outdated and the new version is not working fine. so I manually coping the older releases and try to compile go-kerala.

Eventhough some of the folder exists in the path I get error.

For example, /home/rajkumar/go/src/github.com/ipfs/go- ipfs/Godeps/_workspace/src/github.com/jbenet/go-base58 (from $GOPATH) is present after I have manually copied older release file but still go-get command gives error.

 $go get -d github.com/llSourcell/kerala

Is there any step I'm missing to resolve the error.

Answer 1

You've copied outdated code, which won't compile.

code.google.com/p/go.net/context

code.google.com has shut down, this is an old import path which can no longer be used. The error tells you what has gone wrong, that path can't be imported as it doesn't exist (try visiting it in a browser).

You could try to spend a lot of time fixing up the old imports, only to find that the packages have changed anyway and will no longer compile, so I'd recommend starting with the latest version and contacting the authors of github.com/ipfs/go-ipfs on github, or choosing another package to work with.
