I tried to run https://www.mediawiki.org/wiki/Manual:Pywikibot/movepages.py by the following command in PAWS shell by firefox browser 102.13.0esr (64-bit)
python movepages.py -lang:ta -family:wikisource -pairsfile:"move-pages-py3.txt" -noredirect -always -noredirect summary:பக்கப்பெயரில் சீர்மை
PAWS terminal shows the following error:
CRITICAL: Exiting due to uncaught exception TranslationError: No English translation has been defined for TranslateWiki key
"movepages-moving". It can happen due to lack of i18n submodule or
files or an outdated submodule. See
