Google更改软件包的网址时该怎么办？

When I tried to upgrade third party packages, things went wrong. It seems Google has changed the url of those packages. What should I do now?

$ go get -u all

1. If any code of yours is using the google cloud API packages directly, update them to the new URL. If any of your dependent packages use the cloud API packages, make sure they get updated.
2. Delete the /Users/laike9m/Dev/Go/src/google.golang.org/cloud directory so that go get -u all stops trying to update the stuff under it and making noise.

Once whatever was bringing in the cloud packages is updated, it will download them under the new cloud.google.com path and everything will be fine.
