Nokogiri 1.5.2不安装在Ubuntu 11.10上 [英] Nokogiri 1.5.2 not installing on Ubuntu 11.10
本文介绍了Nokogiri 1.5.2不安装在Ubuntu 11.10上的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
真的很快，我知道一个类似的问题。但是，遵循最高评分的答案不起作用。我已经重新启动了我的系统和终端，但无济于事。
出于某种原因，Nokogiri不承认我拥有 libxslt1- dev 已安装，尽管我明确地安装了它，都使用 sudo apt-get install libxslt-dev 和 sudo apt-get安装libxslt1-dev 。
这是输出;我错过了其他什么？
$ gem install nokogiri -v'1.5.2'
构建原生扩展。这可能需要一段时间...
错误：安装nokogiri时出错：
错误：无法构建gem本机扩展。
〜/ .rvm / rubies / ruby-1.9.3 -p125 / bin / ruby extconf.rb

libxslt缺失。请访问

*** extconf.rb失败***
由于某种原因无法创建Makefile，可能缺少
必需的库和/或头文件。查看mkmf.log文件以获取更多
的详细信息。您可能需要配置选项。

Gem文件将保留安装在~/.rvm/gems/ruby-1.9.3-p125@rails3tutorial2ndEd/宝石/ nokogiri-1.5.2进行检查。
结果记录到~/.rvm/gems/ruby-1.9.3-p125@rails3tutorial2ndEd/gems/nokogiri-1.5.2/ext/nokogiri/gem_make.out
编辑：仔细检查后，我发现安装程序认识到我有 libxslt1-dev 已安装，但未通过其中一项测试。编辑2：我试图安装 capybara 我安装了什么错误吗？ $ c> with bundle install ，以及它的几个依赖项中， nokogiri 和 selenium-webdriver 找不到 libxslt ，因此我不能使用 capybara 。
编辑3：下面是来自 mkmf.log 文件的错误消息;让我知道你是否需要其余部分。

解决方案
好像您有多个 libxml2 （可能还有 libxslt ），并且它们互相混淆。尝试搜索并从系统中删除这些库（及其包含文件）的任何额外副本。
Real quick, I am aware of a similar question. However, following the top rated answer does not work. I've already restarted my system and the terminal, but to no avail.
For some reason, Nokogiri does not recognize that I have libxslt1-dev installed, though I explicitly installed it, both with sudo apt-get install libxslt-dev and sudo apt-get install libxslt1-dev.
Here's the output; am I missing anything else?
$ gem install nokogiri -v '1.5.2'

EDIT: Upon closer inspection, I realize that the installer recognizes that I have libxslt1-dev installed, but it's failing one of the tests. Did I do something wrong with the installation?
EDIT 2: I am trying to install capybara with bundle install, and among its several dependencies, nokogiri and selenium-webdriver cannot find libxslt, and therefore I cannot use capybara.
EDIT 3: Here's the error message from the mkmf.log file; let me know if you need the rest of it.
