Bob,
You can set the registry in the .npmrc file to your internal npm registry. MyEclipse will pick up the registry that is defined in the .npmrc when you run the npm commands from the Terminal+ view.
Run this command : npm config set registry <registry url>
from the Terminal+ view to set the registry in the .npmrc file. Alternatively, you can also add this line directly to the .npmrc file : registry=<registry url>
.The .npmrc file will be located in your user home directory.
Hope this helps. Please let us know how it works for you.
