Description
By following the tutorial the npm link command results in a "permission denied" error message. I already purged the whole project directory and started all over. The issue remained:

The log adds the following information:
0 info it worked if it ends with ok
1 verbose cli [ '/usr/bin/node', '/usr/local/bin/npm', 'link' ]

The message is misleading, though. The link target simply doesn't exist:
$ ls -lap /usr/local/lib/node_modules/
total 12
drwxr-xr-x 3 root root 4096 Sep 4 22:27 ./
drwxr-xr-x 5 root root 4096 Sep 4 22:27 ../

Did I miss a step?
