ruby-on-rails - 无法安装 nokogiri gem

Question

我正在 Arch Linux 上安装 nokogiri 1.6.6.2，因为没有它就无法继续安装 metasploit。我得到以下输出:

[ blackarch Downloads ]# gem install ./nokogiri-1.6.6.2.gem                       
Building native extensions.  This could take a while...
ERROR:  Error installing ./nokogiri-1.6.6.2.gem:

************************************************************************
IMPORTANT NOTICE:

Building Nokogiri with a packaged version of libxml2-2.9.2
with the following patches applied:
    - 0001-Revert-Missing-initialization-for-the-catalog-module.patch
    - 0002-Fix-missing-entities-after-CVE-2014-3660-fix.patch

Team Nokogiri will keep on doing their best to provide security
updates in a timely manner, but if this is a concern for you and want
to use the system library instead; abort this installation process and
reinstall nokogiri as follows:

    gem install nokogiri -- --use-system-libraries
        [--with-xml2-config=/path/to/xml2-config]
        [--with-xslt-config=/path/to/xslt-config]

If you are using Bundler, tell it to use the option:

    bundle config build.nokogiri --use-system-libraries
    bundle install

Note, however, that nokogiri is not fully compatible with arbitrary
versions of libxml2 provided by OS/package vendors.

我已经尝试了我找到的所有可能的解决方案，无论是本地安装还是 gem install nokogiri 都不起作用...

你可以试试:

bundle config build.nokogiri --use-system-libraries
