No npm-debug.log file was created. Installed right from the included Dockerfile and as instructed in the README.

npm Version: 3.10.8
NodeJS Version: 6.9.1

Node version 6.5.0 with npm 3.10.3 works.

Read the Dockerfile and README installation instructions first, then run the documented npm run boot command against Node.js 6.9.1 and npm 3.10.8. Compare the setup with the reported working Node.js 6.5.0 environment and verify that the server starts from src/index.js without the babel-node error.
