there is no local data directory

Error message

there is no local data directory

What it means

The DATA_DIR lazy static in komorebic resolves the per-user local data directory via dirs::data_local_dir() and appends 'komorebi'. If the OS cannot determine the local data dir (on Windows: %LOCALAPPDATA%), komorebic panics with 'there is no local data directory'.

Solutions

1. Ensure the LOCALAPPDATA environment variable is set (typically C:\Users\<user>\AppData\Local)
2. Run komorebic as an interactive user, not a SYSTEM/service account
3. Repair the Windows user profile if AppData folders are missing
4. Upgrade komorebi in case a newer version handles missing data dirs differently

Example fix

// before: fails when LOCALAPPDATA is unset
komorebic state
// after (cmd)
set LOCALAPPDATA=C:\Users\me\AppData\Local
komorebic state

# PowerShell: ensure LOCALAPPDATA resolves before running komorebic
if (-not $env:LOCALAPPDATA -or -not (Test-Path $env:LOCALAPPDATA)) {
  throw "LOCALAPPDATA is not set/valid; komorebic will panic"
}

When it happens

Trigger: dirs::data_local_dir() returns None, which on Windows happens when %LOCALAPPDATA% / the user profile is not resolvable in the environment running komorebic.

Common situations: Running komorebic from a service or scheduler with LOCALAPPDATA unset; corrupted user profile; launching from a sandboxed/minimal environment where the standard Windows shell folders are unavailable.
