nokogirigem安装错误
我知道关于这个gem有很多问题，但没有答案为我工作。
当我在SSH中运行gem install nokogiri我得到这个错误：
Extracting libxml2-2.8.0.tar.gz into tmp/x86_64-unknown-linux-gnu/ports/libxml2/2.8.0...

我的主机告诉我，所有的库都安装好了。 以下是执行安装nokogiri命令后的完整日志：

macOS High Sierra 10.13
gem install nokogiri -- --use-system-libraries=true --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.13.sdk/usr/include/libxml2/
macOS Sierra 10.12：
gem install nokogiri -- --use-system-libraries=true --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk/usr/include/libxml2/
OS X El Capitan 10.11
gem install nokogiri -- --use-system-libraries=true --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/libxml2/
如果您没有权限，请考虑添加sudo 。
出于某种原因，苹果公司的优胜美地版本OSX没有系统可访问的libxml2安装。 Nokogiri需要这个才能进行编译，幸运的是Xcode有一个与它捆绑在一起的libxml2版本 – 我们只需要在安装gem的时候指定它。 正确安装Nokogiri是非常重要的，因为从现在开始，Rails 4.2.1.rc4会自动尝试安装它，您将感到痛苦。
结帐这个职位了解更多信息 。
最后，这个问题是由nokogiri本身引起的，它自己的libxml2与某些系统不兼容。
所以要安装nokogiri我不得不告诉它，它应该使用系统库。
我手动安装它：
gem install nokogiri -v 1.6.2.1 -- --use-system-libraries
它运作良好。 其他答案没有解决它。
我遇到了同样的问题，因为未列出的构build依赖关系。 当我find有问题的tmp目录时：
find ~/.rbenv/ -name patch.log
它说：
sh：patch：找不到命令
修正了一个简单的问题：
sudo yum install -y patch
在OSX优胜美地，我做了xcode-select --install在terminal。 之后， bundle工作与该gem罚款。
这适用于Windows 7家庭普通版64位：
gem install nokogiri -v 1.6.2.1 -- --use-system-libraries
这与OS X优胜美地为我工作。
gem install nokogiri -v 1.6.5 -- --use-system-libraries
这是在OS X 10.10.3上为我工作的优胜美地：
sudo gem install nokogiri -- --use-system-libraries --with-xslt-dir=/usr/local/opt/libxslt --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/libxml2 --with-xml2-lib=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/lib
就像wongzigii说，安装命令与macOS Sierra的标志一起使用
gem install nokogiri -- --use-system-libraries=true --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk/usr/include/libxml2/
在Mac OS上安装Nokogiri El Capitan：
brew install libxml2 bundle config build.nokogiri "--use-system-libraries --with-xml2-include=/usr/local/opt/libxml2/include/libxml2"
bundle install
它为我工作:)
这对我工作：
sudo gem install nokogiri -v 'versionNumber' -- --use-system-libraries --with-xslt-dir=/usr/local/opt/libxslt --with-xml2-include=/Applications/Xcode-beta.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/libxml2 --with-xml2-lib=/Applications/Xcode-beta.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/lib
目前的答案没有为我工作（我使用Ubuntu 16.04，而不是Mac）。
然而，按照Nokogiri网站的说明，这部分就是这样做的：
# See http://www.nokogiri.org/tutorials/installing_nokogiri.html#ubuntu___debian sudo apt-get install build-essential patch sudo apt-get install ruby-dev zlib1g-dev liblzma-dev
注意自2009年以来我一直在使用Nokogiri，而且我一直安装时遇到问题。 任何进一步的评论可能不符合SO T＆C 🙂
最后经过了很多努力，以下为我工作（OS X 10.8.5，macports）。 （我正在安装github页面，即jekyll）
/opt/local/bin/gem install nokogiri -v 1.6.6.2 -- --use-system-libraries --with-xslt-dir=/usr/local/opt/libxslt --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/usr/include/libxml2 --with-xml2-lib=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/usr/lib
我正在使用macOS Sierra。
去nokogiri文件，并按照这个：
在MAC OSX上
使用Nokogiri的售货libxml2和libxslt，安装应该Just Work™。
首先，确保你有最新版本的RubyGems和xcode命令行工具：
1 gem update --system
2 xcode-select --install
然后安装nokogiri：
1 gem install nokogiri
在我运行之前，Nokogiri没有在我的OSX Sierra机器上findXcode库：
sudo xcodebuild -license accept
