安装ffi ruby​​ gem时无法找到ffi.h

标签: ruby rubygems ffi compass

Ruby版本2.2.4p230

RubyGem版本2.7.2

安装了Ruby-devel和lib64ffi-devel。

使用64位OpenMandriva 3.0,urpmi和rpmdrake。

目标:安装罗盘,但首先需要宝石ffi。

我在过去的两天里一直在努力搜索互联网而且我很难过......我不可能安装早期版本的ruby,因为它依赖于较老的ncurses。我觉得替换ncurses会打开一堆令人讨厌的蠕虫。

然而......我也对罗盘替代方案完全开放,其中config.rb项目文件可以以某种方式移植/复制,因此罗盘和其他sass编译器都可以运行。 (这是为了工作,我们不会很快改变sass建设者。)

/usr/share/gems/gems/ffi-1.9.18/ext/ffi_c完全存在,该目录中有一个ffi.c文件,但在附近找不到任何ffi.h文件。在绝望的时刻,我触摸了该目录中的ffi.h,当我运行gem install时,它将其移除。 ;)我会尝试复制别人的libs,看看是否有效。

基本上任何方法都可以在不破坏其他软件包的情况下实现此功能。我不会将红宝石用于其他任何事情,只需指南针。

这是输出:

您的错误消息显示:

  

/usr/share/ruby/mkmf.rb:456:在“ try_do”中:编译器无法生成可执行文件。 (RuntimeError)   您必须先安装开发工具。

这就是解决问题的方法:

xcode-select --install

(但请事先确保xcode-select -p将路径返回到稳定的Xcode版本,例如Xcode 10)
