webdriver-manager update error: EACCES, permission denied

Question

I used to run Protractor tests successfully (on Mac) and I tried to upgrade version, so I ran

$npm install -g protractor

and it seemed like it worked - when running

$protractor --version

I get

Version 1.8.0

but now, when running

$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?

You need to run webdriver-manager update with sudo:

$ sudo -s
$ webdriver-manager update
