Ruby 1.8.7 for Linux OS 的 Nokogiri 安装错误

Question

我正在 Linux 操作系统上使用 Rails 3.2.1 和 ruby​​ 1.8.7。 我正在尝试在 WHM 服务器上为 Authorize-net gem 安装 Nokogiri。我收到以下错误：

gem install nokogiri -v '1.5.0'

Building native extensions.  This could take a while...
ERROR:  Error installing nokogiri:
        ERROR: Failed to build gem native extension.

        /usr/bin/ruby extconf.rb
checking for libxml/parser.h... yes
checking for libxslt/xslt.h... no
-----
libxslt 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.

mkmf.log 文件指出缺少 libxslt。

尝试安装 libxslt-ruby 时，我收到以下错误：

mkmf.log 文件指出：

conftest.c:1:21: error: ruby/io.h: No such file or directory

我在 Windows 机器上开发，但客户端的服务器是 Linux。我试过谷歌搜索，但没有运气。

任何帮助将不胜感激！

提前致谢！

我认为“缺少 libxslt”并不意味着您必须安装 gem libxslt-ruby。它告诉你安装 package libxslt-dev.

只需关注http://nokogiri.org/tutorials/installing_nokogiri.html 并运行：

sudo apt-get install libxslt-dev libxml2-dev
sudo gem install nokogiri
