Early Oct. 2019, I ran into a problem on our Voter Guide where Circle Ci would fail before tests would even run. I could get a basic sense of what was happening via the Circle-Ci interface, but the problem wasn't immediately evident.

After consulting with Andrew Chavez, he pointed me to a page that explains how to SSH into a build running on Circle-Ci to run the commands step-by-step in an attempt to debug the problem.

After SSH-ing in, and cd-ing into the directory on the running build (in this case, cd voter-guide), you're able to run the commands listed in the circle-ci/config.yaml file in the project and seeing the read-out within the terminal as you go along.

In this instance, part of the setup process of the circle ci box involves running this command, which pulls a setup file for Nodejs v 8.x and installs it:

curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
