Fatal error: Unable to find local grunt.

[m2b]

I am trying
brew reinstall --HEAD grafana/grafana/grafana to get latest build.

Am I supposed to be in particular directory? The solutions from http://gruntjs.com/getting-started say to make sure the runner is installed in your project directory. What project and what directory?

FRAGMENT OF OUTPUT:

Fatal error: Unable to find local grunt.

If you're seeing this message, grunt hasn't been installed locally to
your project. For more information about installing and configuring grunt,
please see the Getting Started guide:

@m2b I had tobrew uninstall grafana then brew install grafana --head to get past the grunt error.
