Ruby 构建geocanvas本机扩展失败

我正在四处寻找类似的问题，但我找不到尚未实施的解决方案：

我已经安装了ruby和gems，但是有点问题，我无法更新软件包

$ yum install gcc gcc-c++ ruby ruby-devel rubygems

Loaded plugins: langpacks, refresh-packagekit
Package gcc-4.8.2-7.fc20.x86_64 already installed and latest version

Package rubygems-2.1.11-115.fc20.noarch already installed and latest version
Nothing to do

Ruby版本：

$ ruby -v
ruby 2.0.0p353 (2013-11-22 revision 43784) [x86_64-linux]

我粘贴出现在goocanvas上的消息，更新为root：

问题是这些gems是通过fedora存储库安装的

---

使用yum卸载并使用gem重新安装，成功了。

您是否已安装？是的，它已安装：

pango-1.36.1-2.fc20.x86_64

PS：谢谢您的更正。您有什么建议？您是否查看了引用的日志（

/usr/local/share/gems/gems/pango-2.1.0/ext/pango/gem_make.out

）？您应该在这里包含它（除非它与输出中已经包含的内容完全相同）。是的，它是相同的。但是，必须更新并显示相关错误的软件包如下：

goocanvas（1.2.6<2.1.0）gstreamer（2.0.2<2.1.0）gtk2（2.0.2<2.1.0）pango（2.0.2<2.1.0）

通常，总是使用RubyGems来安装gems，而不是OS软件包管理器（可能是yum、apt等）。
