change your file permissions .. like this

first check who owns the directory

ls -la /usr/local/lib/node_modules it is denying access because the node_module folder is owned by root

drwxr-xr-x 3 root wheel 102 Jun 24 23:24 node_modules so this needs to be changed by changing root to your user but first run command below to check your current user How do I get the name of the active user via the command line in OS X?

id -un OR

whoami

then change owner

sudo chown -R [owner]:[owner] /usr/local/lib/node_modules OR

sudo chown -R ownerName: /usr/local/lib/node_modules OR

sudo chown -R $USER /usr/local/lib/node_modules
