Mystery: Aurelia install and build sometimes fails when run in the deployment target after Kudu Sync.

The problem is these two commands.

npm install -y --production
node_modules/.bin/au build --env production

Those two commands

• work on a development machine,
• work in the Azure App Service, if we run them in the deployment source (before Kudu Sync), and
• sometimes do not work, if we run them in the deployment target (after Kudu Sync).

When those commands do not work in the deployment target (i.e. in D:\home\site\wwwroot ), they still do not work if we "Redeploy" - unless we delete everything in wwwroot before doing the redeploy.

What exactly do we need to delete for the redeploy to work?

• node_modules
• scripts
• src
• something-else ?

We prefer to run those two problematic commands inside the deployment target, because then we do not have to re-install all of the node_modules , which we do not store in version control.
