这是因为你的环境变量设置不正确或者缺少相关依赖包。建议你按照以下步骤操作：

1. 确认你是否已经安装了相关的依赖包。可以使用以下命令进行安装：

go get -u github.com/cespare/cp
go get -u github.com/ethereum/go-ethereum/common
go get -u github.com/ethereum/go-ethereum/crypto/signify
go get -u github.com/ethereum/go-ethereum/internal/build
go get -u github.com/ethereum/go-ethereum/params

2. 确认你的环境变量设置是否正确。你可以使用以下命令查看你的环境变量：

echo $GOPATH
echo $GOROOT

其中 `$GOPATH` 表示你的 `go` 项目所在目录，`$GOROOT` 表示 `go` 的安装路径。如果这些变量没有设置或者设置不正确，你需要重新设置它们。

3. 如果你的 `go` 版本较老，可以考虑升级到最新版。你可以使用以下命令进行升级：

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install golang

升级后，你需要重新设置环境变量。

通过以上步骤的操作，你应该可以解决这个问题。
