NPM run build error - bower is not recognized as an internal or external command.

When building out the widget everything looked like it was working correctly. When I went to run the build command I got the following error.

~/Desktop/arcgis-web-appbuilder-2.20/ArcGISWebAppBuilder/widget-developemnt $ npm run build
