But we can also import the package using the path to the package. For example, if we have a package called vmimpl in /home/user1/vmimpl, then we can import it using the following command:8import "home/user1/vmimpl"9If we have a package called vmimpl in /home/user1/vmimpl, then we can import it using the following command:10import "home/user1/vmimpl"11But if we use the package name to import the package, then we should have the package in the GOROOT or GOPATH. If we have a package called vmimpl in /home/user1/vmimpl, then we can import it using the following command:12import "home/user1/vmimpl"13If we have a package called vmimpl in /home/user1/vmimpl, then we can import it using the following command:14import "home/user1/vmimpl"15If we have a package called vmimpl in /home/user1/vmimpl, then we can import it using the following command:16import "home/user1/vmimpl"17But if we use the package name to import the package, then we should have the package in the GOROOT or GOPATH.
