i don't have protractor , chrome canary install don't think they're related. @ least few weeks ago building fine without them.

i tried put require('typescript-require');(https://github.com/eknkc/typescript-require) gulpfile here , there wihout success.

so highly appreciated.

for me fix error manually install type definitions:

cd tools  tsd install
