For the specific error you’re getting, it seems like something is off in the way the client and it’s dependencies have been installed. That said…

You’re using a client that is end of life from what I can see above. The current release as of this writing is 2.3.1 and the docs cover how to set it up and do a simple get. See the line with bucket.get() in that code sample.
