npm install fails on Windows7 cmd

[PipStyles]

Error: ./node_modules/bower/bin/bower install '.' is not recognized as an internal or external command, operable program or batch file.

Unix assumed? This fails through both windows command prompt and Git bash.

Edit1: having already got bower installed and in PATH, changing the postinstall task in package.json to "bower install" alone appears to solve this issue. (Consider a note in the instructions?)
