go 1.18 in google.cloud - go

Question

Description
I am trying to install a library from a go v1.18 program to access Google Cloud.
Previously, the "go get" command was used, but since version 1.18, it is no longer available.
It seems to use go install, but I get an error when executing the command.
% go install cloud.google.com/go/bigquery
go: 'go install' requires a version when current directory is not in a module
Try 'go install cloud.google.com/go/bigquery#latest' to install the latest version
% go install cloud.google.com/go/bigquery#latest
package cloud.google.com/go/bigquery is not a main package
% go install cloud.google.com/go#latest
package cloud.google.com/go is not a main package
Environments

Self resolved.
-> change package name "main"

go install is used to install binary programs available on the package. Usually command line tools.
go get, until go1.18, was used to update packages and install programs, they change it by split in several programs
Seems there is nothing to install. Also the main package is not bigquery but cloud.google.com/go
If you want to install a dependency, if you are using vendorized modules you can do
$ go get -u cloud.google.com/go/bigquery
$ go mod tidy
$ go mod vendor
If not, you may try it by running go mod init first
