在Windows中找不到供应商包

Question

I have my GOPATH and GOROOT set, currently trying to use a package located in the vendor folder, while doing go run in my windows I get

C:esume>go run docs/generator.go
docs\generator.go:13:2: cannot find package "github.com/tidwall/gjson" in any 
of:
    C:\Go\src\github.com\tidwall\gjson (from $GOROOT)
    C:esume\src\github.com\tidwall\gjson (from $GOPATH)

My GOROOT=C:\Go, GOPATH=C:esume and PATH=C:\Go\bin
