Unable to run script provided by installed gem

[pfaffle]

I have automation which runs in a Jenkins pipeline which uses the Ruby Docker container as the execution environment. Just last night, a job started failing because it was unable to find a script that is provided by a gem that I install as part of the job.

It seems the scripts are landing in /usr/local/bundle/bin, but that directory is not on my path.

I'm using the ruby:2.4 image. Below is some output from me reproducing the error on my local workstation and poking around at the environment and filesystem in the container:

docker run -it ruby:2.4 /bin/bash

Duplicate of #211 and #212, fixed by #209.

Sorry for the duplicate report. I just pulled the latest build down from Docker Hub though and it still has the issue. Do I just need to wait for a new build?
