Clean install Ember-cli


I want to do a clean install on my Mac (10.11.4). I’ve tried to reinstall, Node, npm, Ember-cli… But I still get errors after creating a new project and starting with Ember server ([BABEL] Note: The code generator has deoptimised…, The Broccoli Plugin: [Babel] failed with:…) . I tried to do a new installation on another iMac (10.11.4) and there it works fine.


Perhaps try ??:

  1. npm uninstall -g ember-cli – Remove old global ember-cli
  2. npm cache clean – Clear NPM cache
  3. bower cache clean – Clear Bower cache
  4. npm install -g ember-cli – Install new global ember-cli


Did all that, several times, no luck at all. There must be something more…


It must be something local. I’ve created another user on my mac. Just did ember new abc and ember serve, It worked! What can be wrong?


Perhaps it is a bug? I read this:



@Frank_Stock did you solve?


I don’t know if it will help but I now use “n” to manage my node versions.
