E0030

Warning name: missing_package_alias

The package alias is empty. The default package alias will be used instead. This warning applies to the legacy moon.pkg.json format. Current moon commands reject JSON manifests, and moon.pkg cannot express an explicitly empty alias. The examples below are retained as migration references.

Erroneous example

moon.pkg.json

{
  "import": [
    {
      "path": "moonbit-community/E0030/lib",
      "alias": ""
    }
  ]
}

Suggestion

Use a non-empty alias for the package:

moon.pkg.json

{
  "import": [
    {
      "path": "moonbit-community/E0030-fixed/lib",
      "alias": "hello"
    }
  ]
}
