Expected behaviour

NPM Install should failed when failed to download standalone. This may be caused by network issue getting github assets or missing curl.

Actual behaviour

The installation was successful without any errors. The tar.gz file in node_modules/@pact-foundation/pact-node/standalone have zero size.
