SLC Command not found

Im using Mac OS X 10.10.2 .

node -v v0.12.1 npm -v 2.5.1 Installing the Package worked only with sudo even when i fixed the permission rights via

$ sudo chown -R $USER /usr/local/bin $ sudo chown -R $USER /usr/local/lib/node_modules Without sudo it throws EACCS error´s http://ift.tt/19u54p1

/usr/local/bin/npm/node_modules/strongloop/bin/slc exists. Any thoughts?
