goget命令不提供输出也不起作用

$ go help get
usage: go get [-d] [-f] [-fix] [-insecure] [-t] [-u] [build flags] [packages]

Get downloads the packages named by the import paths, along with their
dependencies. It then installs the named packages, like 'go install'.

The -u flag instructs get to use the network to update the named packages
and their dependencies.  By default, get uses the network to check out
missing packages but does not use it to look for updates to existing packages.

The -v flag enables verbose progress and debug output.

如果无事可做，那么就没有报告可言。例如，当go get首次运行时，它将下载并安装，之后将不执行任何操作，因为无需执行任何操作，除非您强制执行更新：

$ go get -v github.com/aclements/perflock/cmd/perflock 
github.com/aclements/perflock (download)
github.com/aclements/perflock/internal/cpupower
github.com/aclements/perflock/cmd/perflock
$ go get -v github.com/aclements/perflock/cmd/perflock 
$ go get -v github.com/aclements/perflock/cmd/perflock 
$ go get -v -u github.com/aclements/perflock/cmd/perflock 
github.com/aclements/perflock (download)
$ go get -v -u github.com/aclements/perflock/cmd/perflock 
github.com/aclements/perflock (download)
$ go get -v github.com/aclements/perflock/cmd/perflock 
$ go get -v github.com/aclements/perflock/cmd/perflock
