我正在使用 Ubuntu 20.04.3 LTS，VSCode 1.62.3，去 1.17.3 linux/amd64
当我在 VSCode 中启动调试器时，它会向我显示此警告
“dlv-dap”命令不可用。请选择“安装”，或按照此处的安装说明进行操作。来源：Go（扩展）[安装] [全部安装]
我单击安装并在输出中看到：
Tools environment: GOPATH=/home/raspberry/GolandProjects
Installing 1 tool at /home/raspberry/GolandProjects/bin in module mode.
dlv-dap

"stderr": "go: cannot find GOROOT directory: /snap/bin/go\n"
}
1 tools failed to install.
dlv-dap: failed to install dlv-dap(github.com/go-delve/delve/cmd/dlv@master): Error: Command failed: /usr/local/go/bin/go get -x -d github.com/go-delve/delve/cmd/dlv@master
go: cannot find GOROOT directory: /snap/bin/go
当我通过 go 工具检查 GOROOT 时，我看到：
$ go env GOROOT
/usr/local/go
当我检查 /snap/bin/ 时，我看到：
~$ cd /snap/bin/
:/snap/bin$ ls
canonical-livepatch pre-commit.validate-config
go pre-commit.validate-manifest
gofmt snap-store
go.gofmt snap-store.ubuntu-software
pre-commit snap-store.ubuntu-software-local-file
我很困惑，有 /snap/bin/go 但是 VSCode 告诉我没有并且无法运行调试器。如何解决？
更新 1
当我通过在控制台中输入以下内容将 GOROOT 设置为 /snap/bin/go 时：
$ export GOROOT=/snap/bin/go
当我尝试运行调试器时，VSCode 开始打印：
Couldn't find dlv-dap at the Go tools path, /home/raspberry/GolandProjects/, /home/raspberry/GolandProjects or /usr/local/go/bin:/home/raspberry/.local/bin:/home/raspberry/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
