husky: V9 doesn't work after install

Basically what I did:

npm install --save-dev husky

and then:

npx husky init

file:///Users/.../project/node_modules/husky/bin.js:10
  ;(d.scripts ||= {}).prepare = 'husky'
              ^^^

SyntaxError: Unexpected token '||='
    at Loader.moduleStrategy (internal/modules/esm/translators.js:149:18)
    at async link (internal/modules/esm/module_job.js:67:21)
