Common errors

error ModuleNotFoundError: No module named 'romkan2' ↓

cause Library not installed or installed under a different name.

fix

pip install romkan2

error ImportError: cannot import name 'to_romaji' from 'romkan2' ↓

cause Possible installation corruption or very old version (pre-0.1.0).

fix

pip install --upgrade romkan2

Warnings

gotcha The 'to_romaji' function may return 'konnnichiha' (with double n) for 'こんにちは' due to Hepburn romanization rules; not a bug. ↓

fix Use 'to_kana' to reverse; accept double n as standard Hepburn.

deprecated Unlike the older 'romkan' library, 'romkan2' does not support custom romanization systems or extended conversions like 'to_hepburn'. ↓

fix If you need custom systems, consider using 'pykakasi' instead.
