I'm running into an error where vendor packages are not being correctly resolved by go; on macOS High Sierra 10.13.6. I'll use github.com/gorilla/mux as an example package
$ echo $GOPATH

I'm importing the package with
import (
...
"github.com/gorilla/mux"
...
)
When running:
go build -o out main.go
I get the following error for each package in vendor
main.go:6:2: cannot find package "_/Users/gregorysims/go/src/site/user/project/vendor/github.com/gorilla/mux" in any of:
/usr/local/go/src/_/Users/gregorysims/go/src/site/user/project/vendor/github.com/gorilla/mux (from $GOROOT)
/Users/gregorysims/go/src/_/Users/gregorysims/go/src/site/user/project/vendor/github.com/gorilla/mux (from $GOPATH)
The folder should be found at
/Users/gregorysims/go/src/site/user/project/vendor/github.com/gorilla/mux
and is present in the directory.
Why is this being prefixed the following?
/Users/gregorysims/go/src/_
UPDATE
After deleting the local project and recloning from remote, I attempted to build without having any of the dependencies downloaded. This had the expected output:
main.go:6:2: cannot find package "github.com/gorilla/mux" in any of:
/usr/local/go/src/github.com/gorilla/mux (from $GOROOT)
/Users/gregorysims/go/src/github.com/gorilla/mux (from $GOPATH)
The above error is produced only after the build command is run after dep ensure is run.
UPDATE 2
Creating an empty vendor directory changes the output to:
main.go:6:2: cannot find package "github.com/gorilla/mux" in any of:
/Users/gregorysims/go/src/site/user/project/vendor/github.com/gorilla/mux (vendor tree)
/usr/local/go/src/github.com/gorilla/mux (from $GOROOT)
/Users/gregorysims/go/src/github.com/gorilla/mux (from $GOPATH)
Update 3
To simulate dep I called go get github.com/gorilla/mux followed by:
mv $GOPATH/src/github.com/gorilla/mux $GOPATH/src/site/user/project/vendor/github.com/gorilla/mux
After doing so, the problem surfaces again.
