我刚为Ruby安装了“续集”宝石。我想试试Sequel网站的例子,它不会起作用:( test.rb:
require 'rubygems'
require 'sequel'
DB = Sequel.sqlite # memory database
DB.create_table :items do
primary_key :id
String :name
Float :price
end
items = DB[:items] # Create a dataset
# Populate the table
items.insert(:name => 'abc', :price => rand * 100)
items.insert(:name => 'def', :price => rand * 100)
items.insert(:name => 'ghi', :price => rand * 100)
# Print out the number of records
puts "Item count: #{items.count}"
# Print out the average price
puts "The average price is: #{items.avg(:price)}"
控制台:
$ sequel test.rb
Error: ArgumentError: syntax error on line 11, col 37: `i'/usr/lib/ruby/1.8/yaml.rb:133:in `load'
答案 0 :(得分:2)
您需要使用ruby
而不是sequel
$ ruby test.rb
