我在尝试安装ffi gem时遇到错误:
~ - 16:54>gem i ffi
Building native extensions. This could take a while...
ERROR: Error installing ffi:

我在安装带有原生扩展的gem时遇到各种各样的错误,所以我认为我的Ubuntu安装有些问题,但我不知道是什么.我会发布您诊断问题所需的任何信息.
编辑:当我cd到ffi gem(在第二行但在最后一行中提到),并在第6行运行rake行时,我得到"找不到RubyGem rake-compiler".
在我的rake-compiler之后,再次运行rake,我得到了这个:
configure: error: source directory already configured; run "make distclean" there first
