bower_components/bitcoinjs-lib/build dosen't exist

[coopci]

I added "bitcoinjs-lib": "~1.5.7" to bower.json, otherwise, even bower_components/bitcoinjs-lib dosen't exist.
Now my problem is there is no "build" subfolder under bower_components/bitcoinjs-lib:

# ls www/bower_components/bitcoinjs-lib/
LICENSE  package.json  README.md  src  test

I tried:

 browserify -r bitcoinjs-lib -s Bitcoin > bitcoinjs-lib.js

And copied the resulting bitcoinjs-lib.js to bower_components/bitcoinjs-lib/build, the Error: Bitcoin is undefined disappeared in browser, but more

Her spouse works n the s I see your name I believe and and thethat I have the kids by her name is Jamie kimball and need people have souls and massive amount of money for me it's n the millions of dollars I find this completely disturbing see I wish I was wrong but I have been returned any of my assets I've heard nothing from anyone at get hub I've had the same account since 2013 n one-day it disappears I think they think I'm stupid n don't understand but yeah I'm about drop a unrecoverable lawsuit n win fasho guarantee I hope this is taken seriously N I contacted treated fairly

First of all my work has came to an halt until I get all my other assets back I'm missing a major amount of assets and there's nothing that I even want to even think about more than you get my web belongs to me back I don't see it on my new profile I don't understand how my other profile was just shut down the way it was all right I have a lot of things missing here and it makes me very upset I'm about to walk up in this building in a minute if somebody going to explain something to me otherwise I swear before God and I don't even mean to throw a text like this but this is outrageous this is freaking outrageous I'm telling me
