WARNING (edit)

Doing a chmod 777 is a fairly radical solution. Try these first, one at a time, and stop when one works:

• $ sudo chmod -R 777 /usr/local/lib/node_modules/npm
• $ sudo chmod -R 777 /usr/local/lib/node_modules
• $ sudo chmod g+w /usr/local/lib
• $ sudo chmod g+rwx /usr/local/lib

$ brew postinstall node is the only install part where I would get a problem

Permission denied - /usr/local/lib/node_modules/npm/.github

So I

// !! READ EDIT ABOVE BEFORE RUNNING THIS CODE !!
$ sudo chmod -R 777 /usr/local/lib
$ brew postinstall node

and viola, npm is now linked

$ npm -v
3.10.10

Extra

If you used -R 777 on lib my recommendation would be to set nested files and directories to a default setting:

• $ find /usr/local/lib -type f -print -exec chmod 644 {} \;
• $ find /usr/local/lib -type d -print -exec chmod 755 {} \;
• $ chmod /usr/local/lib 755
