【解决方案1】：

> brew update
> brew install libxml2 libxslt libiconv

> brew --prefix libxml2
/usr/local/opt/libxml2

> brew --prefix libxslt
/usr/local/opt/libxslt

> brew --prefix libiconv
/usr/local/opt/libiconv

> gem uninstall nokogiri

> gem install nokogiri -v 1.6.3.1 -- --with-xslt-dir=/usr/local/opt/libxslt --with-iconv-dir=/usr/local/opt/libiconv --with-xml2-config=/usr/local/opt/libxml2/bin/xml2-config --with-xslt-config=/usr/local/opt/libxslt/bin/xslt-config

基于：Mac fix 1 - Install the Nokogiri gem on Mac OS 10.9 Mavericks

其他解决方案：

> gem install nokogiri -v 1.6.3.1 -- --use-system-libraries --with-xml2-include=/usr/local/opt/libxml2/include/libxml2/

来自 cmets 的另一个解决方案：

> xcode-select --install gem install nokogiri

【讨论】：

我认为不需要--prefix（我从未使用过）只需 brew install 二进制库然后执行gem install nokogiri
我正在使用它来获得正确的路径，对我来说它是必需的
在 10.10 Yosemite 中为我工作（没有 xcode-select..）
为什么每次我更新 osx 时只有 nokogiri 失败。好痛
对我有用的是上面提到的gem install nokogiri -v x.x.x -- --use-system-libraries --with-xml2-include=/usr/local/opt/libxml2/include/libxml2/

【解决方案2】：

以下内容在 Yosemite 10.10.3 上为我工作：

sudo gem install nokogiri -- --with-xml2-include=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/libxml2 --use-system-libraries

【解决方案3】：

酿造更新 brew install libxml2 libxslt libiconv

brew --prefix libxml2 /usr/local/opt/libxml2

brew --prefix libxslt /usr/local/opt/libxslt

brew --prefix libiconv /usr/local/opt/libiconv

gem 卸载 nokogiri

gem install nokogiri -v 1.6.3.1 --with-xslt-dir=/usr/local/opt/libxslt --with-iconv-dir=/usr/local/opt/libiconv --with-xml2 -config=/usr/local/opt/libxml2/bin/xml2-config --with-xslt-config=/usr/local/opt/libxslt/bin/xslt-config

【解决方案4】：

如果您使用 bundle install --path vendor/bundle 将 gem 安装到本地文件夹并出现错误

Building nokogiri using packaged libraries.
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

然后，你需要做以下使用

bundle config build.nokogiri --use-system-libraries
bundle install --path vendor/bundle

然后安装将通过
