Answer 1

When you instantiate a Javascript Smart Contract the Fabric creates a chaincode container and installs your Javascript contract (or sample) AND all the npm dependencies. This means that an npm registry with those modules must be accessible.

I suspect that you are behind a corporate proxy/firewall, or working in a region where there is no direct access to npm. On your host machine you probably have a .npmrc file which helps with the proxy, and you need to replicate that for the chaincode.

I think you need to place the .npmrc file in the root folder of your Smart Contract project - i.e. in the same folder as the package.json file.
