fail to load custom template path

[lawplatform]

I try to load hygen from custom template path
HYGEN_TMPLS= ~/.hygen/_templates hygen comp init

but it try to refer pnpm/global path

/home/tree/.local/share/pnpm/global/5/.pnpm/hygen@6.2.11/node_modules/hygen/src/templates

should I use npm only to use custom template path ?
