No permission to create new ember-cli app

Everytime I use the command ember new myapp it throws me these errors:

/usr/local/lib/node_modules/ember-cli/node_modules/configstore/index.js:53
                throw err;
                ^

Error: EACCES: permission denied, open '/Users/MyAccount/.config/configstore/ember-cli.json'
You don't have access to this file.

I tried to clean npm cache, but the problem remains. How to correct this?
