input stops randomly

When executing the "npm install" example the input hangs (on rPi and mac) at different but reproducable points (debug is to process.stdout):

mac (OS X10.6.8) -------->

npm init

Press ^C at any time to quit.

rPi ----------->

npm init

This utility will walk you through creating a package.json file.
It only covers the most common items, and tries to guess sane defaults.

See npm help json for definitive documentation on these fields
and exactly what they do.

Use npm install <pkg> --save afterwards to install a package and
save it as a dependency in the package.json file.

Press ^C at any time to quit.

Any ideas?

Start by reproducing the npm install example, specifically the npm init prompts, on the macOS and Raspberry Pi environments described, using the listed Node.js versions. Compare where input stops responding and verify that the interactive input completes without hanging on both platforms.
