Spectral Docker Develop Image - Module Not Found

Describe the bug Attempting to use the linter provided by the Spectral docker image (https://hub.docker.com/r/stoplight/spectral) and getting a node “Module Not Found” error. This only seems to happen with the develop tag, which I am utilizing because I wanted to make use of the new Junit formatter (https://github.com/stoplightio/spectral/pull/519).

To Reproduce

stoplight/spectral:latest (completes without error):

docker run -v "$(pwd):/app" stoplight/spectral:latest lint "/app/storage/api-docs/api-docs.json" --verbose --format=json --output="/app/api-violations.json" 

spotlight/spectral:develop (throws error):

docker run -v "$(pwd):/app" stoplight/spectral:develop lint "/app/storage/api-docs/api-docs.json" --verbose --format=junit --output="/app/api-violations.json"

Stacktrace

    throw err;
    ^

}

Expected behavior I expected the linter command to complete without errors and populate the report in junit format.

Environment (remove any that are not applicable):

• Library version: Latest build published to DockerHub (https://github.com/stoplightio/spectral/tree/12ca287175001865235a9871e035b5a03540aff4)
• OS: Host OSX, but running in Docker.

Debugging Attempts

• Tried to create a new dockerfile and add the required module myself in the build but was not successful.
• Googled the missing module and haven’t found a clear source of the problem.

It turns out it’s used in another part as well. #592

Junit is in v4.2.0-beta2 so you can npm install that. 😎
