錯誤的MAC（libxml2的）安裝引入nokogiri 1.6.0

Question

更新：修正

我發現在另一個線程的答案。我使用的解決方法是告訴引入nokogiri使用系統庫，而不是：

NOKOGIRI_USE_SYSTEM_LIBRARIES=1 bundle install

試圖在Mac上安裝引入nokogiri 1.6.0。以前的版本，我沒有問題。但1.6.0拒絕安裝。這是錯誤：

似乎它與libxml2 tar文件無法提取有關。

任何想法？我做了8個小時的研究，但無濟於事。謝謝！

Answer 1

我在另一個線程中找到了答案。我使用的解決方法是告訴引入nokogiri使用系統庫，而不是：

NOKOGIRI_USE_SYSTEM_LIBRARIES=1 bundle install 

Answer 2

創建文件build_nokogiri（或其他），並填寫：

#!/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 

給執行該文件的權限。

執行文件。

這將自動解決使用brew安裝的依賴關係。
