无法从这些信息中真正理解。尝试查看config.log。 如果您是第一次安装，请尝试使用rbenv。按照以下步骤安装Ruby 2.0：

git克隆git://github.com/sstephenson/rbenv.git rbenv先生 echo'export PATH=$HOME/.rbenv/bin:$PATH'>>~/.bash\u配置文件 echo“eval$rbenv init-”>~/.bash\u配置文件 git克隆git://github.com/sstephenson/ruby-build.git ~/.rbenv/plugins/ruby build source~/.bash_配置文件 rbenv安装2.0.0-p247 rbenv全球2.0.0-p247 rbenv再灰烬 ruby-v这是为了检查ruby是否已安装 gem安装绑定器

从头开始：您使用了什么安装说明？您首先键入了什么？可能是损坏的gcc安装。您在config.log文件中看到了吗？您是否尝试过从软件包中安装它？卸载用sudomakeinstall安装的东西是一项相当棘手的任务。这要简单得多。
