Ruby HTTParty soundcloud gem 错误

Question

我正在尝试使用 soundcloud gem，但突然间我发出的每个请求总是出错。

例如下面的代码：

require 'soundcloud'

client = SoundCloud.new(:client_id => MY_CLIENT_ID)

track_url = 'https://soundcloud.com/sohight/sohight-cheevy-money-is-love-out-now'

track = client.get('/resolve', :url => track_url)
puts track.genre

有人知道我为什么会收到这个错误吗？

可能是 HTTParty 中的错误。

hash_conversions.rb 的第 33 行：

param << "#{key}=#{ERB::Util.url_encode(value.to_s)}&"

将它放在脚本的顶部，然后重试：

require 'erb'
