necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Gem files will remain installed in /usr/lib64/ruby/gems/1.9.1/gems/linecache19-0.5.12 for inspection.

如何追踪此错误？就我所知，gem_make.out中没有任何内容特别有用：

我的部署需要ruby 1.9.2p290，所以提升版本不是一个可悲的选择。我是否得到错误似乎要求的额外库/标题？

Answer 1

您的部署需要1.9.2，而您的回溯表明您使用的是1.9.1。也许切换到正确的ruby版本。

此外，如果您的应用包含ruby-debug19（需要linecached19），请尝试切换为debugger。
