How do I get a refresh token for command line gsutil to work? - google-cloud-storage

Question

I use gsutil to transfer files from a Windows machine to Google Cloud Storage.
I have not used it for more than 6 months and now when I try it I get:
Failure: invalid_grant
From researching this I suspect the access token is no longer valid as it has not been used for 6 months, and I need a refresh token?
I cannot seem to find how to get and use this.
thanks
Running gsutil -DD config produces the following output:

Answer 1

You can ask gsutil to configure itself. Go to the directory with gsutil and run this:
c:\gsutil> python gsutil config
Gsutil will lead you through the steps to setting up your credentials.
That said, access tokens only normally last about a half hour. It's more likely that the previously-configured refresh token was revoked for some reason. Alternately, you can only request new tokens at a certain rate. It's possible your account has been requesting many, many refresh tokens for some reason and has been temporarily rate limited by the access service.

Answer 2

The command to authenticate is now
$ gcloud auth login
That should refresh your grant and get you going again.
You may also want to run
$ gcloud components update
to update your installation.

Answer 3

Brandon Yarbrough gave me suggestions which solved this problem. He suspected that the .boto file was corrupted and suggested I delete it and run gsutil config again. I did this and it solved the problem.
