在捆绑安装中安装nokogiri 1.5.9

Question

当我使用nokogiri运行bundle install时出现此错误:

Gem::Installer::ExtensionBuildError: ERROR: Failed to build gem native extension.

        /usr/bin/ruby1.9.1 extconf.rb 
checking for libxml/parser.h... no

libxml2 is missing.  please visit http://nokogiri.org/tutorials/installing_nokogiri.html for help with installing dependencies.

*** 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
        ....


Gem files will remain installed in /var/lib/gems/1.9.1/gems/nokogiri-1.5.9 for inspection.
Results logged to /var/lib/gems/1.9.1/gems/nokogiri-1.5.9/ext/nokogiri/gem_make.out

An error occurred while installing nokogiri (1.5.9), and Bundler cannot
continue.
Make sure that `gem install nokogiri -v '1.5.9'` succeeds before bundling.

我怎么能纠正它？

你需要在nokogiri之前安装一些库

在Ubuntu中:

sudo apt-get install libxslt-dev libxml2-dev
