Ruby-无法加载文件（LoadError）

Question

我安装了ruby-aaws gem，并尝试运行示例脚本。 我收到以下错误。 有什么我想念的吗？

1. gem install ruby-aaws

2. amazon.rb

require 'amazon/aws'
require 'amazon/aws/search'

include Amazon::AWS
include Amazon::AWS::Search

ASSOCIATES_ID = "************"
KEY_ID = '**************'

il = ItemLookup.new( 'ASIN', { 'ItemId' => 'B001COU9I6',
'MerchantId' => 'Amazon' })

rg = ResponseGroup.new( 'Medium' )

req = Request.new(KEY_ID, ASSOCIATES_ID)

resp = req.search( il, rg)
item_sets = resp.item_lookup_response[0].items
item_sets.each do |item_set|
item_set.item.each do |item|
attribs = item.item_attributes[0]
puts attribs
end
end

Answer 1

您的系统中缺少iconv ，或者您的版本与其他软件包的要求不符。

检查是否安装了iconv

iconv --version

要么

which iconv

安装iconv gem

gem install iconv

要么

rvm pkg install iconv

如果没有任何效果，请尝试旧版本/其他版本

gem install iconv -v '~> 1.0.3'
