Parse error in handlebars\base.js

[ghost]

Not sure if this code is too old to run now, but when I follow the instructions on a windows machine I get stopped at:

$ grunt server
Running "clean:dev" (clean) task Running "browserify:app" (browserify) task

C:\Users\user1\benm\node_modules\handlebars\lib\handlebars\base.js:1
module Utils from "./utils";
^
ParseError: Unexpected identifier
Warning: Error running grunt-browserify. Use --force to continue. Aborted due to warnings.
