rake db:create
We could not find your database: postgres. Which can be found in the database configuration file located at config/database.yml.

To resolve this issue:

• Did you create the database for this app, or delete it? You may need to create your database.
• Has the database name changed? Check your database.yml config has the correct database name.

To create your database, run:

    bin/rails db:create

Couldn't create 'myapp_development' database. Please check your configuration.

i have paste it

this is everything from my database
PostgreSQL. Versions 9.3 and up are supported.

Install the pg driver:

gem install pg

On macOS with Homebrew:

gem install pg -- --with-pg-config=/usr/local/bin/pg_config

On macOS with MacPorts:

gem install pg -- --with-pg-config=/opt/local/lib/postgresql84/bin/pg_config

On Windows:

gem install pg

Choose the win32 build.

Install PostgreSQL and put its /bin directory on your path.

Configure Using Gemfile

gem "pg"

c

default: &default
host: localhost
adapter: postgresql
encoding: unicode
username: postgres
password: password

# For details on connection pooling, see Rails configuration guide
# https://guides.rubyonrails.org/configuring.html#database-pooling

development:
<<: *default

# The specified database role being used to connect to postgres.
# To create additional roles in postgres see $ createuser --help.
# When left blank, postgres will use the default role. This is
# the same name as the operating system user running Rails.
#username: myapp

# The password associated with the postgres role (username).
#password:

# Connect on a TCP socket. Omitted by default since the client uses a

# domain sockets, so uncomment these lines.

# The TCP port the server listens on. Defaults to 5432.
# If your server runs on a different port number, change accordingly.

Warning: The database defined as "test" will be erased and

re-generated from your development database when you run "rake".

Do not set this db to the same as development or production.

test:
<<: *default
database: myapp_test

As with config/credentials.yml, you never want to store sensitive information,

like your database password, in your source code. If your source code is

ever seen by anyone, they now have access to your database.

Instead, provide the password or a full connection URL as an environment

variable when you boot the app. For example:

DATABASE_URL="postgres://myuser:mypass@localhost/somedatabase"

If the connection URL is provided in the special DATABASE_URL environment

variable, Rails will automatically merge its configuration values on top of

the values provided in this file. Alternatively, you can specify a connection

URL environment variable explicitly:

production:

url: <%= ENV["MY_APP_DATABASE_URL"] %>

Read https://guides.rubyonrails.org/configuring.html#configuring-a-database

for a full overview on how database connection configuration can be specified.

production:
<<: *default
database: myapp_production
username: myapp
password: <%= ENV["MYAPP_DATABASE_PASSWORD"] %>

please help i have tried everything this is what i have
