Expected behavior

Build functions with use of the TSLint

Actual behavior

See error, without ./node_modules/.bin/tslint -p tslint.json && it's builds fine

PS: npm bugs functions then you get functions but not firebase-functions?!

[inlined]

What happens if (from your functions directory) you run ./node_modules/.bin/tslint -p tslint.json ? It sounds like you have a linter error, which should have been printed earlier in the debug output.

Yep, it was a linter error... hanging on a import that was never used
