npm install error

[fpirotti]

Hello, I am trying to contribute to some improvements (in particular allow options in searchOSM and searchGoogle), but when I try to run npm install I get the following (npm version=6.9.0, node.js version=10.16.0)

leaflet-pulse-icon@0.1.0 postinstall /archivio/home/pirotti/devel/leaflet.extras/node_modules/leaflet-pulse-icon
gobble build -f dist
