installed package not found

Error message

installed package not found

What it means

GetInstalledPackageSize scans all locally installed packages of the given pkgType and, when none has a package.json `name` matching packageName, returns this sentinel error. It means the package is not recognized as installed — its directory is missing, its package metadata failed to parse, or the name does not match. It is an internal lookup failure, not a size-calculation failure.

Solutions

1. Verify the package exists under the workspace dir for its type (themes/, icons/, plugins/, widgets/, templates/) with a valid package.json whose name matches
2. Check for typos in packageName and that pkgType is correct
3. Reinstall the package from the marketplace, then query its size
4. If the folder exists but is corrupt, delete it and reinstall

Example fix

// before: querying size for a package assumed installed
size, _, err := model.GetInstalledPackageSize("plugins", "my-plugin")
// after: guard with the installed list first
if !isPackageInstalled("plugins", "my-plugin") { return errors.New("package not installed") }
size, _, err := model.GetInstalledPackageSize("plugins", "my-plugin")

func isPackageInstalled(pkgType, name string) bool {
  pkgs := model.GetInstalledPackages(pkgType, "", "")
  for _, p := range pkgs { if p.Name == name && p.InvalidReason == "" { return true } }
  return false
}

if info == nil || info.Pkg == nil || info.Pkg.Name != wantName { return false }

size, _, err := model.GetInstalledPackageSize(pkgType, name)
if err != nil {
  if strings.Contains(err.Error(), "installed package not found") { /* treat as absent, size 0 */ }
  return err
}

When it happens

Trigger: Calling the kernel API that queries an installed package's size (GET /api/bazaar/getInstalledPackageSize style flows) with a pkgType/packageName that is not currently installed; the package directory was deleted manually; package.json in the package dir is missing/corrupt so info.Pkg.Name never matches; or a typo in the package name.

Common situations: Stale frontend state after manually deleting a theme/icon/plugin folder from the workspace; querying a package by marketplace name while the installed copy declares a different name in its package.json; calling before the first install ever happened.
