Make sure that gem install nokogiri -v '1.8.5' --source 'http://gems.ruby-china.com/' succeeds before bundling.
解决

• brew install libxml2 libxslt
• gem install nokogiri -- --use-system-libraries --with-xml2-include=brew --prefix/opt/libxml2/include/libxml2 --with-xml2-lib=brew --prefix/opt/libxml2/lib --with-xslt-dir=brew --prefix/opt/libxslt --with-iconv-include=brew --prefix/opt/libiconv/include/
