在Ubuntu 12.10中安装Nokogiri（v.1.5.0。）Gem [英] Installing Nokogiri (v.1.5.0.) Gem In Ubuntu 12.10

问题描述

我试图在Ubuntu 12.10上安装foodcritic gem。它可以成功安装在Ubuntu 12.04中。我已经安装了需求： libxslt-dev ， libxml2-dev ， ruby​​1.9.3 和 make 包。但是，现在我试试

  sudo gem install foodcritic 
  

我得到以下错误：

 编译xml_xpath_context.c 
 xml_xpath_context.c：在函数'xpath_generic_exception_handler'中：
 xml_xpath_context.c：184：3：错误：格式不是字符串文本，也没有格式参数[-Werror = format-security] 
 cc1：视为错误
 make：*** [xml_xpath_context.o]错误1 
 
 Gem文件将保留安装在/usr/lib/ruby/gems/1.9.1/gems/nokogiri- 1.5.0进行检查。 
结果记录到/usr/lib/ruby/gems/1.9.1/gems/nokogiri-1.5.0/ext/nokogiri/gem_make.out 
  

Nokogiri-1.5.0宝石是foodcritic的一个要求，而且它的市场定位失败了。
如何安装foodcritic？

解决方案

支持Ubuntu 12.10（或任何基于Debian的系统，使用 -Werror = format-security ）内置于nokogiri-1.5.4中。我建议安装最新的（目前1.5.5）。它应该与1.5.0兼容，但有更多固定的bug除外:)有关更多信息，请参见更新日志。

由于1.5.3的段错误，看起来像 foodcritic 将版本锁定为1.5.0（根据 更新日志），但其中一项修正在1.5.4中修复了段错误，所以你可能想要修改gem来要求〜> 1.5.4 如果可以，请联系该宝石的作者。

I am trying to install foodcritic gem on Ubuntu 12.10. It could be successfully installed in Ubuntu 12.04. I have installed the requirements: libxslt-dev, libxml2-dev, ruby1.9.3 and make packages. But when now I try

sudo gem install foodcritic

I get the following error:

compiling xml_xpath_context.c
xml_xpath_context.c: In function ‘xpath_generic_exception_handler’:
xml_xpath_context.c:184:3: error: format not a string literal and no format arguments [-Werror=format-security]
cc1: some warnings being treated as errors
make: *** [xml_xpath_context.o] Error 1

Gem files will remain installed in /usr/lib/ruby/gems/1.9.1/gems/nokogiri-1.5.0 for inspection.
Results logged to /usr/lib/ruby/gems/1.9.1/gems/nokogiri-1.5.0/ext/nokogiri/gem_make.out

Nokogiri-1.5.0 gem is a requirement for foodcritic and it is it's instllation that fails. How can I install foodcritic?

解决方案

Support for Ubuntu 12.10 (or any Debian-based system that uses -Werror=format-security) was built into nokogiri-1.5.4. I recommend installing the latest (currently 1.5.5). It should be compatible with 1.5.0, except with more fixed bugs :) See the changelog for more information.

It looks like foodcritic locked the version to 1.5.0 because of a segfault in 1.5.3 (according to its changelog) but one of the fixes in 1.5.4 fixes a segfault, so you may want to modify the gem to require ~> 1.5.4 and if it works, contact the author of the gem.
