TypeError: Cannot call method 'ast_walker' of undefined

I'm trying to run locally and I'm getting this error, the same using facebook/powereditor who uses uki.
Somebody told me I should change uglify's version, but I do rollback until uglify-js@2.3.6 and still getting error.

any solution?!, I've just installed it on CentOS with the same exact error

@minakolta Not yet, I had to change my UI stack at that time. Now I don't know if there's a solution

You can fix this if you roll back to uglify-js 1.3.4. You'll also need express circa v2.5:

npm uninstall uglify-js
npm install uglify-js@1.3.4

npm uninstall express
npm install express@2.5.0

@mgdombrowski Thanks Sir, that's resolved the problem
