Webdriver-manager update error: EACCES, permission denied

Question

I used Protractor tests successfully (on Mac) and I tried updating the version, so I ran

$npm install -g protractor

and it seemed like it worked - at startup

$protractor --version

I get

Version 1.8.0

but now at startup

$webdriver-manager start

I get

 fs.js:642
  return binding.mkdir(pathModule._makeLong(path),
             ^
Error: EACCES, permission denied   '/usr/local/lib/node_modules/protractor/selenium'

any ideas?
