When I try to package a project where I have created a network dataset (In ArcMap since ArcGIS Pro does not allow building network datasets yet), I get this error: 00189: The network dataset must be in a geodatabase. The error refers me to here: 00189: The network dataset must be in a geodatabase—ArcGIS Pro | ArcGIS Desktop
However, this site does not tell me HOW to place the network dataset in a geodatabase. Any assistance appreciated.
