How to install third party go library in fabric container

I used the simplejson library in my chaincode, and when I try to deploy my chaincode, I got below error, how could I install this library into the fabric container? should I install this library in Order or the peer which I installed my chaincode?

When I go into the container (docker exec -it peer0 /bin/bash), and try to run go get github.com/bitly/go-simplejson, it tell me the go command not recognized.

You might need to vendor all dependent packages (including shim) within your chaincode.

There is a good tutorial that would be very helpful https://www.youtube.com/watch?v=-mlUaJbFHcM
