Boa tarde,
fiz o passo a passo para instalação do rails, do bundle conforme na aula 1 de Rails 4. Mas na hora que coloco localhost:3000, aparece o seguinte erro:
ActiveRecord::ConnectionNotEstablished No connection pool for ActiveRecord::Base Extracted source (around line #570): 568 569 570 571 572 573
def retrieve_connection(klass) #:nodoc:
pool = retrieve_connection_pool(klass)
raise ConnectionNotEstablished, "No connection pool for #{klass}" unless pool
conn = pool.connection
raise ConnectionNotEstablished, "No connection for #{klass} in connection pool" unless conn
connRails.root: /home/nan/code/cs101/ruby-logic/lojadecamisetas
minha versão do Rails é a 4.2.8, do ruby 2.6.3
me ajudem por favor...
