ruby-on-rails - Gem 安装忽略 nokogiri 的标志

Question

我正在尝试安装 nokogiri 1.6.0 版，但遇到了一些问题。

$ 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.

如您所见，我使用:--with-xml2-dir=/usr/local/Cellar/libxml2/2.9.1 --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.28 但是 extconf.rb 使用 libxml2-2.8.0.tar.gz 与 xslt 相同，它使用 libxslt-1.1.26.tar.gz

如何解决这个问题，因为更改版本实际上不是一个选项？ 谢谢

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"

希望对您有所帮助。
