Permission denied browserRepositoryPublic.json

Hi Hacklone I did the following steps:

• npm install -g private-bower
• private-bower

I get the following error :

[bower]  17/4/18 15:38:40   Refreshing public packages...
[bower]  17/4/18 15:38:40   private-bower server started
[bower]  17/4/18 15:38:48   Loaded public packages
[bower]  17/4/18 15:38:48   Error caching public registry
{ Error: EACCES: permission denied, open '/usr/local/lib/node_modules/private-bower/bowerRepositoryPublic.json'
  errno: -13,
  code: 'EACCES',
  syscall: 'open',
  path: '/usr/local/lib/node_modules/private-bower/bowerRepositoryPublic.json' }```

Sorry if the issue already resolved , couldn't find it myself
