go - non-standard import in standard package windows -

i can't seem run go code because of error

non-standard import "gopkg.in/olivere/elastic.v5" in standard package "goprojects/search"

main.go located at: c:\go\src\goprojects\search\main.go

goroot c:\go

gopath c:\go\src\goprojects (tried adding current working directory here \search, didnt help)

when run "go gopkg.in/olivere/elastic.v5" imported files in c:\go\src\goprojects\src\gopkg.in\olivere\elastic.v5

visual studio code giving me message

cannot find package "go.pkg.in/olivere/elastic.v5" in of:

c:\go\src\vendor\gopkg.in\olivere\elastic.v5 (vendor tree)

c:\go\src\gopkg.in\olivere\elastic.v5 (from $goroot)

c:\go\src\goprojects\src\gopkg.in\olivere\elastic.v5 (from $gopath)

my code

package main  import (     "fmt"     "net/http"      elastic "gopkg.in/olivere/elastic.v5" )  func main() {     http.handlefunc("/search", search)     http.listenandserve(":3000", nil) }  func search(w http.responsewriter, r *http.request) {     searchstring := r.url.query().get("q")     fmt.println("searching for" + searchstring)      // create client     client, err := elastic.newclient()      w.write([]byte(searchstring)) } 

moved goprojects out of goroot path , separate folder in c:\goprojects , replaced gopath new path , worked.
