Question

我正在尝试在新的rails项目中安装nokogiri v 1.6.7.2。我正在运行Kali Linux（基于debian）。这是堆栈跟踪：

    $ gem install nokogiri -v '1.6.7.2' -- --use-system-libraries
Building native extensions with: '--use-system-libraries'
This could take a while...
ERROR:  Error installing nokogiri:
    ERROR: Failed to build gem native extension.

    /usr/bin/ruby2.2 -r ./siteconf20160405-3609-rdkvif.rb extconf.rb --use-system-libraries
checking if the C compiler accepts ... yes
Building nokogiri using system libraries.
libxml2 version 2.6.21 or later is required!
*** extconf.rb failed ***
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.

Provided configuration options:
    --with-opt-dir
    --without-opt-dir
    --with-opt-include
    --without-opt-include=${opt-dir}/include
    --with-opt-lib
    --without-opt-lib=${opt-dir}/lib
    --with-make-prog
    --without-make-prog
    --srcdir=.

    --clean
    --use-system-libraries
    --with-zlib-dir
    --without-zlib-dir
    --with-zlib-include

    --with-libexslt-config
    --without-libexslt-config
    --with-pkg-config
    --without-pkg-config

extconf failed, exit code 1

Gem files will remain installed in /var/lib/gems/2.2.0/gems/nokogiri-1.6.7.2 for inspection.
Results logged to /var/lib/gems/2.2.0/extensions/x86_64-linux/2.2.0/nokogiri-1.6.7.2/gem_make.out

我已经检查过安装了libxml2：

apt-get install libxml2
Reading package lists... Done
Building dependency tree       
Reading state information... Done
libxml2 is already the newest version (2.9.3+dfsg1-1).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

我在其他线程中看到尝试使用--use-sytem-libraries标志，但仍然会导致相同的错误。我错过了什么？

谢谢！

除了libxml2和libxslt之外，您还需要一些额外的开发库。使用sudo apt-get install ruby-dev zlib1g-dev liblzma-dev安装它们。更多信息https://github.com/sparklemotion/nokogiri.org-tutorials/blob/master/content/installing_nokogiri.md。
