Try running: ``` git config --global core.autocrlf false ``` Then delete the repository and clone it again. ## Extra yarn files If you have extra files created by yarn (`yarn.lock`, `.yarnrc.yml`, `.yarn`), you may have a yarn version issue.

This documentation includes [different ways](/start/local-setup/yarn-setup#step-2-set-up-postgresql-database) to set up your postgres instance. If you're successful in running this provisioning, you should have `default` and `metadata` schemas in your database. If you don't, make sure you don't have more than one postgres instance running on your computer.
