I also tested further: in live i also can not reproduce it, but when travis-ci is used to test things it breaks with this error ... any idea why?!
see https://travis-ci.org/Apollon77/ioBroker.nut (don't know if reachable from outside)

[mattberther]

Im not really sure -- the travis build for this project runs just fine.

[Apollon77]

SOLVED: The reason whs an "unmet peer dependency" with npm 3.x and that's why it seems that something was not correctly installed. very strange. After manually installing winston before the real project in travis.yml it worked.
Maybe helps someone else too :-)

[mattberther]

Great! Thanks for following up. :)
