我正在尝试使用 Rubyripper（一个可从此处下载的 CD 翻录程序：http://code.google.com/p/rubyripper) 在 Ubuntu 17.10 上。它是一个脚本和一堆文件；您安装依赖项并运行脚本。我已经在多个版本的 Ubuntu 上使用过它，包括最近的 17.04，没有问题。我最近刚刚安装了 17.10。（我也在我使用的另一台计算机上尝试过这个更新从 17.04 到 17.10，结果相同。
使用 Rubyripper 运行的脚本如下所示：
#!/usr/bin/env ruby

ICONDIR=[ENV['PWD'], "/usr/share/icons/hicolor/128x128/apps"]
RUBYDIR=[ENV['PWD'], File.dirname(__FILE__), "/usr/local/lib/site_ruby/2.3.0"]
found_rrlib = false
RUBYDIR.each do |dir|
if File.exist?(file = File.join(dir, '/rr_lib.rb'))
require file; found_rrlib = true ; break
end
end
if found_rrlib == false
puts "The main program logic file 'rr_lib.rb' can't be found!"
exit()
end
begin
require 'gtk2'
rescue LoadError
puts "The ruby-gtk2 library could not be found. Is it installed?"; exit()
end
当我运行这个程序时，我得到了返回The ruby-gtk2 library could not be found. Is it installed?。该包ruby-gtk2肯定已经安装：
rowand@desktop:~$ sudo apt-get install ruby-gtk2
Reading package lists... Done
Building dependency tree
Reading state information... Done
ruby-gtk2 is already the newest version (3.1.8-6ubuntu1).
0 to upgrade, 0 to newly install, 0 to remove and 0 not to upgrade.
我认为问题在于 17.10 下相关文件的位置与脚本预期的位置不同，也与 17.04 下的位置不同。因此，我尝试编辑脚本的以下行，保存它，然后再次运行它。
RUBYDIR=[ENV['PWD'], File.dirname(__FILE__), "/usr/local/lib/site_ruby/2.3.0"]
根据的搜索/usr，我尝试了以下操作：
RUBYDIR=[ENV['PWD'], File.dirname(__FILE__), "/usr/lib/ruby/vendor_ruby/2.3.0"]
RUBYDIR=[ENV['PWD'], File.dirname(__FILE__), "/usr/lib/ruby/vendor_ruby"]
RUBYDIR=[ENV['PWD'], File.dirname(__FILE__), "/usr/lib/ruby/vendor_ruby/gtk2"]
RUBYDIR=[ENV['PWD'], File.dirname(__FILE__), "/usr/lib/x86_64-linux-gnu/ruby/vendor_ruby/2.3.0"]
它们都不起作用。我一直收到相同的错误 ( The ruby-gtk2 library could not be found. Is it installed?)。
的回报sudo dpkg -L ruby-gtk2是：

我的问题是：我应该/usr/local/lib/site_ruby/2.3.0用什么来替换才能让 Rubyripper 脚本正确找到ruby-gtk2它正在寻找的库？还是我完全走错了路？如果是这样，有什么建议吗？
答案1
与此相关的行是：
begin
require 'gtk2'
rescue LoadError
puts "The ruby-gtk2 library could not be found. Is it installed?"; exit()
end
这会捕获异常并丢弃调试问题所需的所有信息。如果您将其替换为：
require 'gtk2'
您将收到以下错误信息：
/usr/lib/ruby/2.3.0/rubygems/core_ext/kernel_require.rb:55:in `require': cannot load such file -- cairo-gobject (LoadError)
这清楚地说明了如何解决问题：
sudo apt install ruby-cairo-gobject
希望这对你有用！
