npm install failing in azure on jspm step - azure

Question

ASP.NET app with prepublish step of "npm install" (in project.json). This is failing on the Azure deploy due to not having jspm (which should be installed by npm install). The peer dependencies are also throwing a warning, despite being listed in the package.json. npm install will work locally. Below are the Azure deployment logs and my .json file settings.
