我有RVM正在运行并且它运行良好，但我似乎无法弄清楚如何安装ruby-gnome2。我已按照this tutorial上的步骤操作，这些步骤为：
rvm use 1.9.1 # I use 1.9.1 which should work with ruby-gnome2
wget http://downloads.sourceforge.net/ruby-gnome2/ruby-gnome2-all-0.19.4.tar.gz
tar zxf ruby-gnome2-all-0.19.4.tar.gz
cd ruby-gnome2-all-0.19.4/
ruby extconf.rb —ruby=`which ruby`
make
make install
这不会产生任何错误，所以我认为它有效。所以我试着用它来测试它：
$ irb
irb(main):001:0> require 'gtk2'
这给了我这个错误：
irb(main):001:0> require 'gtk2'
LoadError: no such file to load -- gtk2
为什么我无法安装ruby-gnome2？
答案 0 :(得分：2)
安装系统依赖：
sudo apt-get install libglib2.0-dev libatk1.0-dev libcairo-dev libsqlite3-dev libpango1.0-dev libgtk2.0-dev libgdk-pixbuf2.0
安装gtk2 gem，它是ruby-gnome2：
gem install gtk2
您可以运行这个小脚本来验证是否已安装gtk2：
要求'gtk2'
win = Gtk :: Window.new（“我的ruby-gnome2项目”）
win.show_all
Gtk.main

我希望，当你按照这些说明行事时，就行了：
ruby extconf.rb —ruby=`which ruby`
你实际上：
如果没有，那就是你的错误。
如果你真的做了所有这些，请发布你从ruby extconf.rb ...行获得的输出。

为了为所有依赖项的RVM构建ruby-gnome2，请确保在构建ruby二进制文件之前安装了以下软件包：
sudo apt-get install libatk1.0-dev libpanel-applet-4-dev libgtksourceview2.0-dev libvte-dev libgstreamer0.10-dev libbonobo2-dev libbonoboui2-dev libgtk2.0-dev libgdk-pixbuf2.0-dev libgtksourceview2.0-dev libpango1.0-dev libpoppler-dev libglade2-dev libart-2.0-dev libgnomeprint2.2-dev libgnomecanvas2-dev libgtkglext1-dev libgnomeprintui2.2-dev libgoocanvas-dev libgnomevfs2-dev libgconf2-dev librsvg2-dev
使用以下命令安装后，您可以再次重建它：
rvm install 1.9.1
然后，按照您发布的说明进行操作：
rvm use 1.9.1 # I use 1.9.1 which should work with ruby-gnome2
wget http://downloads.sourceforge.net/ruby-gnome2/ruby-gnome2-all-0.19.4.tar.gz
tar zxf ruby-gnome2-all-0.19.4.tar.gz
cd ruby-gnome2-all-0.19.4/
ruby extconf.rb —ruby=`which ruby`
# Alternatively you may use the following line
# to install into rvm's dir and avoid conflict with system libs
# ruby extconf.rb --ruby=`which ruby` --prefix=$MY_RUBY_HOME
make
make install
