Question

更新：已修复

我在另一个帖子中找到了答案。我使用的解决方法是告诉Nokogiri使用系统库：

NOKOGIRI_USE_SYSTEM_LIBRARIES=1 bundle install

====

尝试在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：

似乎它与libxml2 tar文件无法解压缩有关。

有什么想法吗？我做了大概8个小时的研究无济于事。谢谢！

Answer 2

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。
