Ruby 当我尝试运行bundler时，出现错误：

Gem文件仍将安装在/var/lib/gems/1.9.1/gems/nokogiri-1.5.2中以供检查。 结果记录到/var/lib/gems/1.9.1/gems/nokogiri-1.5.2/ext/nokogiri/gem_make.out

安装nokogiri 1.5.2时出错，捆绑程序无法继续。

---

在绑定之前，请确保gem安装nokogiri-v“1.5.2”成功。

您使用的是哪种操作系统？如果在mac上，请确保您有用于xcode的命令行工具，或者使用“xcode select-install”安装它们。Debian风格的发行版1.5.2中可能存在重复的缺陷。请尝试1.5.4或更高版本。
