Error message

${name} versions are missing for ${packageName}

What it means

The PyPI framework-versions badge throws InvalidResponse when, after fetching the package metadata, no trove classifiers match the `Framework :: <Name> :: <version>` regex — meaning the parsed versions list is empty. It indicates the package (or PyPI response) declares no framework version classifiers for the requested framework.

Solutions

1. Check the package's PyPI page for 'Framework :: X :: version' classifiers and confirm the framework name matches
2. Verify the packageName is the PyPI package that declares those classifiers
3. Add the appropriate Framework classifiers to setup.cfg/setup.py and publish a release

Example fix

// before
setup(..., classifiers=[])  # no Framework:: classifiers
// after
classifiers=["Framework :: Django", "Framework :: Django :: 4.2"]

const meta = await fetch(`https://pypi.org/pypi/${packageName}/json`)
const data = await meta.json()
const has = (data.info?.classifiers ?? []).some(c => c.startsWith(`Framework :: ${framework}`))
if (!has) throw new Error(`${packageName} declares no Framework :: ${framework} classifiers`)

function hasFrameworkVersions(data, framework) {
  return Array.isArray(data?.info?.classifiers) &&
    data.info.classifiers.some(c => new RegExp(`^Framework :: ${framework} :: [\\d.]+$`).test(c))
}

try {
  const badge = await service.handle({ framework: 'django', packageName: 'my-django-app' })
} catch (err) {
  if (err instanceof InvalidResponse && /versions are missing/.test(err.prettyMessage)) {
    return renderBadge({ label: 'django', message: 'n/a' })
  }
  throw err
}

When it happens

Trigger: Requesting e.g. /pypi/frameworkversions/django/<pkg> for a package that has no `Framework :: Django :: x.y` classifiers; a typo'd framework name; a package whose latest release dropped the classifiers.

Common situations: Package authors removing classifiers in a new release; users confusing package name with framework name; PyPI classifier format changes breaking the regex.
