Gem安装忽略nokogiri的标志

Question

我正在尝试安装nokogiri 1.6.0版，并且有一些问题。

$ gem install nokogiri -v '1.6.0' -- --with-xml2-dir=/usr/local/Cellar/libxml2/2.9.1 --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.28 
Building native extensions with: '--with-xml2-dir=/usr/local/Cellar/libxml2/2.9.1 --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.28' 
This could take a while... 
ERROR: Error installing nokogiri: 
    ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of 
necessary libraries and/or headers. Check the mkmf.log file for more 
details. You may need configuration options. 

正如你所看到的，我用：--with-xml2-dir=/usr/local/Cellar/libxml2/2.9.1 --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.28 但extconf.rb使用libxml2-2.8.0.tar.gz 同为XSLT它使用的libxslt-1.1.26.tar.gz

如何解决这个问题，导致改变版本实际上不是一个选项？ 感谢

尝试：

$ gem uninstall nokogiri # JIC 
$ NOKOGIRI_USE_SYSTEM_LIBRARIES=1 gem install nokogiri \ 
    -- --use-system-libraries \ 
     --with-iconv-dir="$(brew --prefix libiconv)" \ 
     --with-xml2-config="$(brew --prefix libxml2)/bin/xml2-config" \ 
     --with-xslt-config="$(brew --prefix libxslt)/bin/xslt-config" 

希望它能帮助。
