How to find out what kind of error is given when trying to run a Gulp task?

Question

npm

if I write in the console "gulp .default" gives the following:

list of package.json dependencies

"devDependencies": {
    "autoprefixer": "^8.0.0",
    "gulp": "github:gulpjs/gulp#4.0",
    "gulp-cheerio": "^0.6.3",
    "gulp-cssnano": "^2.1.2",
    "gulp-postcss": "^7.0.1",
    "gulp-print": "^5.0.0",
    "gulp-rename": "^1.2.2",
    "gulp-replace": "^0.6.1",
    "gulp-sass": "^3.1.0",
    "gulp-svg-sprite": "^1.3.7",
    "gulp-svgmin": "^1.2.4",
    "gulp-uglify": "^3.0.0",
    "gulp-watch": "^5.0.0"
  }

Perhaps someone faced such a problem, where to dig at least? Thank you!
