If using yarn workspaces with webpack-node-externals a better solution than setting modulesFromFile: true is to use the following externals setting in your webpack config:

externals: [
  nodeExternals(),
  nodeExternals({

  }),
],

Essentially using two instances of nodeExternals. 1 for the package node_modules and one for the root node_modules.
