在mac（libxml2）上安装nokogiri 1.6.0时出错
更新：已修复
我在另一个post中找到了答案。 我使用的解决方法是告诉Nokogiri使用系统库：
NOKOGIRI_USE_SYSTEM_LIBRARIES=1 bundle install ====
试图在Mac上安装nokogiri 1.6.0。 在以前的版本中，我没有遇到任何问题。 但1.6.0拒绝安装。 这是错误：

好像它与libxml2 tar文件无法解压缩有关。
有任何想法吗？ 我做了大概8个小时的研究无济于事。 谢谢！
我在另一个post中找到了答案。 我使用的解决方法是告诉Nokogiri使用系统库：
NOKOGIRI_USE_SYSTEM_LIBRARIES=1 bundle install
创建文件build_nokogiri（或其他）并填写：
#!/usr/bin/env ruby class Version attr_reader :major, :minor, :patch, :base def initialize( str ) @base = str base = File.basename str @major, @minor, @patch = base.split('.').map &:to_i end def <=>(other) return -1 if major < other.major return 1 if major > other.mahor return -1 if minor < other.minor return 1 if minor > other.minor return -1 if patch < other.patch return 1 if patch > other.patch 0 end def to_s "##{self.class.name}{#@major #@minor #@patch #@base}" end alias inspect to_s alias dir base def version [major,minor,patch].compact.join('.') end end class Lookup < Version class << self attr_accessor :prefix end def self.find Dir[ "/usr/local/Cellar/#{ full_name }/*" ].map { |c| new c }.sort.first end def self.full_name [prefix, name.downcase].compact.join('') end %w{ include lib }.each { |m| define_method("#{m}_path") { "#{ base }/#{ m }" } } def args %w{ include lib }.map do |c| "--with-#{ self.class.name.downcase }-#{c}=#{ send("#{ c }_path") }" end.join(' ') end end class XML2 < Lookup self.prefix = 'lib' def include_path "#{super}/#{ self.class.full_name }" end end class XSLT < Lookup self.prefix = 'lib' def args "--with-xslt-dir=#{ dir }" end end class Iconv < Lookup self.prefix = 'lib' end puts "Found:" a = [ XML2.find, XSLT.find, Iconv.find ] puts a s=" gem install nokogiri -- #{ a.map(&:args).join(' ') } --use-system-libraries" puts s exec s
授予此文件执行权限。
执行文件。
这将自动解决使用brew安装的依赖项。
