我看到了很多此类问题，但我的情况有点不同，所以我在做bundle install 并得到了这个：

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

libiconv is missing.  Please locate mkmf.log to investigate how it is failing.

An error occurred while installing nokogiri (1.6.5), and Bundler cannot continue.
Make sure that `gem install nokogiri -v '1.6.5'` succeeds before bundling.

我已经安装了 libiconv，我尝试以这种方式 gem install nokogiri -- --with-iconv-dir=/usr/local/Cellar/libiconv/1.14/ gem 安装正常，但是我尝试捆绑时再次遇到相同的错误，同样的情况是当我尝试执行 gem install nokogiri -v '1.6.5' 时，安装正常，我可以在 gems 列表中看到 gem，但似乎 bundler 没有看到它，我试图将它包含在我的 gem 文件中，但仍然有这个错误

这对我有用：http://www.nokogiri.org/tutorials/installing_nokogiri.html#using_nonstandard_libxml2___libxslt_installations

gem install nokogiri -- \
    --use-system-libraries \
    --with-xml2-config=/usr/bin/xml2-config \
    --with-xslt-config=/usr/bin/xslt-config

然后bundle update

【解决方案2】：

您可以使用bundle config 设置该路径：

bundle config build.nokogiri "--with-iconv-dir=/usr/local/Cellar/libiconv/1.14/"
bundle install

将此与 cbertelegni 的响应相结合，它奏效了！

【解决方案3】：

这对我有用bundle config build.nokogiri "--use-system-libraries --with-xml2-include=/usr/local/opt/libxml2/include/libxml2"

运行此命令设置bundle install之前的配置

我从https://github.com/sparklemotion/nokogiri/issues/1099得到了这个解决方案

感谢 Gergo 和 cbertelegni，这对我有用：

bundle config build.nokogiri "-- \
    --use-system-libraries \
    --with-xml2-config=/usr/bin/xml2-config \
    --with-xslt-config=/usr/bin/xslt-config"
bundle install
