在GOLang设置工作区？

Question

我无法以任何方式自定义ArchLinux中的工作区。

    获取图书馆：     

    go get -u github.com/google/gxui
    go get -u github.com/google/gxui/drivers/gl
    go get -u github.com/google/gxui/themes/dark
    

    排气去环境：     

    [continue@LenovoG780 user]$ go env
    GOARCH="amd64"
    GOBIN=""
    GOCHAR="6"
    GOEXE=""
    GOHOSTARCH="amd64"
    GOHOSTOS="linux"
    GOOS="linux"
    GOPATH="/home/continue/go"
    GORACE=""
    GOROOT="/usr"
    GOTOOLDIR="/usr/lib/gcc/x86_64-unknown-linux-gnu/5.3.0"
    CC="/usr/bin/gcc"
    GOGCCFLAGS="-fPIC -m64 -pthread -fmessage-length=0"
    CXX="/usr/bin/g++"
    CGO_ENABLED="1"
    

    汇编：     

    gccgo form.go -fuse-ld=gold -o form
    

    可能是什么问题呢？     提前谢谢。
