deprecated, no livereload


since a few days, I get the following warnings:
ionic $ gulp.env has been deprecated. Use your own CLI parser instead. We recommend using yargs or minimist. [gulp] Using file /whatever/gulpfile.js [gulp] Working directory changed to /whatever has been deprecated. Use task dependencies or task triggering instead.

Livereload in ionic serve doesn’t work then, but to my knowledge nothing else seems broken.

Also, when I run npm install on a blank project, I get a ton of errors around libsass that I really don’t know how to fix.
Here is the content of the dependencies in package.json:
"dependencies": { "gulp": "^3.5.6", "gulp-sass": "^2.0.4", "gulp-concat": "^2.2.0", "gulp-minify-css": "^0.3.0", "gulp-rename": "^1.2.0" }, "devDependencies": { "bower": "^1.3.3", "gulp-sass": "^2.1.1", "gulp-util": "^2.2.14", "shelljs": "^0.3.0" },

Has anyone had the same issue recently? I can’t find whether it was introduced in ionic 1.2 or an update in node or gulp or…
