Today, I encountered the following problems when running Vue run serve

ValidationError: Progress Plugin Invalid Options

        options should NOT have additional properties
        options should NOT have additional properties
        options should NOT have additional properties
        options should pass "instanceof" keyword validation
        options should match exactly one schema in oneOf

So I thought yesterday was fine. Why not today? There should be something wrong with my operation today.

  run `npm fund` for details

34 vulnerabilities (22 moderate, 11 high, 1 critical)

To address issues that do not require attention, run:
  npm audit fix

To address all issues (including breaking changes), run:
  npm audit fix --force

Run `npm audit` for details.

So I changed the package to the cleanest package inside vue2.x and the project ran successfully
