Error when running uglify-js

[Nick K]

Hey,
I'm using Gulp to build my projects and suddenly it stopped working today.

Console:

❯ gulp
util.debug: Use console.error instead
DEBUG: ERROR in file: /srv/http/quiz/web/node_modules/gulp-uglify/node_modules/uglify-js/lib/compress.js / Error: EIO, i/o error
                                                                                                                                             
~http/quiz/web/dash master* 
❯ node -v
v0.12.0

How do I debug it\is it a known issue?
