With the Gemfile updated, reinstall the dependencies: $ bundle installĭoing so updates Gemfile.lock with the changes made previously. For more information on why Postgres is recommended instead of Sqlite3, see why Sqlite3 is not compatible with Heroku. Install Postgres locally now if not present on the system, already. Maintaining parity between development and deployment environments prevents subtle bugs from being introduced because of the differences in those environments. Heroku highly recommends using PostgreSQL locally during development. $ bundle lock -add-platform x86_64-linux -add-platform rubyĬreate a local database: $ bin/rails db:createįor new or existing apps where -database=postgresql wasn’t defined, confirm the sqlite3 gem doesn’t exist in the Gemfile. Move into the application directly and add the x86_64-linux and ruby platforms to Gemfile.lock.
