rake db:create - rake 中止

Question

Hi im trying to follow this link to create a scraper and I am stuck trying to create a db https://towardsdatascience.com/job-board-scraping-with-rails-872c432ed2c8

I get this error when typing rake db:create I've tried creating inside and outside the folder and I get this error I am not sure why, thank you very much. I have been closely following the link so I have all the same files and am sure everything was installed properly.

rake aborted!
ActiveRecord::DatabaseConfigurations::InvalidConfigurationError: 
'{ default =>  }' is not a valid configuration. Expected '' to be a URL string or a Hash.

This is my database.yml file

# SQLite. Versions 3.8.0 and up are supported.
#   gem install sqlite3
#
#   Ensure the SQLite 3 gem is defined in your Gemfile
#   gem 'sqlite3'
#
default: &default
adapter: postgresql
pool: 5
timeout: 5000

development:
<<: *default  
database: scraper_development

test:
<<: *default
database: scraper_test

production:
<<: *default
url: <%= ENV['DATABASE_URL'] %> 

# 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.

Thanks in advance everyone!

Update

Thanks for the pointer I had [the database.yml file] indented but I though an error told me to remove tabs. new issue now:

could not connect to server: No such file or directory
Is the server running locally and accepting connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
Couldn't create 'scraper_development' database.
Please check your configuration.

rails aborted!

I ran into the same problem and what I did was to fix the indentation, and then it worked.

The database.yml file is in YAML format. so make sure the sub-items are indented correctly. Please check the example below on how you are supposed to indent it.

This is how your database.yml file should look like

default: &default
  adapter: postgresql
  pool: 5
  timeout: 5000

development:
  <<: *default  
  database: scraper_development

test:
  <<: *default
  database: scraper_test

production:
  <<: *default
  url: <%= ENV['DATABASE_URL'] %>
