}

but with a mono-repository with a lot of package, knip is running for a while without exiting...

workaround

steps :

• change ignore-workspace-cycles=true by disable-workspace-cycles=true in .npmrc
• in prettier-config :
  • delete "eslint-config": "workspace:*" in package.json
  • change extends: ['eslint-config'], by extends: ['../eslint-config/src/index.cjs'], in .eslintrc.cjs
• in eslint-config :
  • delete "prettier-config": "workspace:*" in package.json
  • change "prettier": "prettier-config", by "prettier": "../prettier-config/index.mjs", in package.json
