pin1yin1 dependencies - may need to add javascript runtime

[fifieldt]

Did not have execjs installed and got an error when trying to import data to the production env.

apt-get install ruby-execjs

fixed it

The execjs package is a gem that we install via bundler, so you should not separately install it via apt. That probably worked because it pulled in another package for the js runtime; I think I use nodejs for that, so that's probably what should go in the installation instructions.
