我正在尝试将Ruby服务器迁移到新服务器。我在mongrel.log文件中看到错误：

这些线是什么意思？

我尝试手动安装yahoo-weather gem，我收到以下错误：

猜测，你错过了雅虎天气宝石。
我强烈建议您使用bundler - 这使得将应用程序部署到具有所有依赖项的一致版本的新计算机上变得更加容易。

Yahoo-weather gem未能安装，因为它对Nokogiri的依赖失败了。这发生的原因是：
libxslt is missing. please visit http://nokogiri.org/tutorials/installing_nokogiri.html for help with installing dependencies.
从错误输出中列出的路径名，我怀疑你是在Linux系统上。您需要确保安装了相应的libxml和libxslt。 Nokogiri页面应该有助于解决这个问题。
