运行Twitter gem版本1.7.2，OSX Lion，Ruby 1.9.2。Twitter的建议返回404？
在Rails控制台..如果你把：
client = Twitter::Client.new(:oauth_token => actual_token_here, :oauth_token_secret => actual_secret_here)
client.suggestions('entertainment')
它从Twitter的API检索结果。但是：
client = Twitter::Client.new
client.suggestions('entertainment')
返回相同的错误：
Twitter::NotFound: GET https://api.twitter.com/1/users/suggestions/entertainment.json: 404: Can't find that category
https://dev.twitter.com/docs/api/1/get/users/suggestions/%3Aslug建议您不需要进行身份验证，使这个API调用。
所以不应该没有令牌的工作呢？ 奇怪的是，我已经要求别人在他们的开发机器上做到这一点，它工作正常。我不知道从哪里出发。我如何追踪问题的来源？
这是完整的跟踪：
Twitter::NotFound: GET https://api.twitter.com/1/users/suggestions/entertainment.json: 404: Can't find that category
