java.lang.ClassNotFoundException: javax.xml.bind.DatatypeConverter (clojurescript figwheel)

$ lein new figwheel foo 
$ cd foo 
$ lein figwheel 

Caused by: java.lang.ClassNotFoundException: javax.xml.bind.DatatypeConverter

なぜだ？といろいろググったが、わからず、２，３時間頑張って、ふとターミナルみたら

$ lein new figwheel foo
Generating fresh 'lein new' figwheel project.

Change into your 'foo' directory

Install npm dependencies via 'npm install'
Then run 'lein figwheel'
Wait for it to finish compiling
A browser window should open to the demo application, if not
then open 'http://localhost:3449/index.html' in your browser

?! 

Install npm dependencies via 'npm install'
Then run 'lein figwheel'

まじかーー！目の前に書いてある、 npm install しろと。。。

無事解決しました。はぁ。。。
