Note that running jsctags' -f - file.js from the command line works just fine

npm install -g underscore fixed it, but then the next error is 'cannot find module ctags.' I'm sure a -g install for ctags would work too, but I shouldn't have to globally install anything for this to work?

The issue was my fault, need

/usr/local/lib/jsctags/

in your NODE_PATH, for example

export NODE_PATH=/usr/local/lib/jsctags/:$NODE_PATH

in your .bashrc

Yes, I was going to say that it sounds like an env variable problem, but good thing you figured it out. I don't really use JavaScript myself so I'm not really familiar with node installation stuff.
