sp-dev-fx-webparts: Running gulp package-solution gives errors unless gulp serve has been run previously

Category

• Question
• Bug
• Enhancement

Expected or Desired Behavior

A solution package should be created using gulp package-solution from a newly scaffolded SPFx solution without errors.

Observed Behavior

If you scaffold a solution and immediately attempt to use gulp package-solution you get errors. If you first do gulp serve, a subsequent attempt at gulp package-solution succeeds. This suggests that there is an error in the gulp dependencies, and that the package-solution task should have a dependency on webpack, write-manifests, copy-assets etc. Note that running gulp build does not solve the problem, you have to go through the gulp serve path.

Steps to Reproduce

Run SharePoint Yeoman generator to create a new SPFx solution using basic JavaScript HelloWorld web part: yo @microsoft/sharepoint. Immediately try to create the deployment package using gulp package-solution.
