【问题描述】:
我一直在尝试在我的计算机(Mountain Lion)上安装 Nokogiri,以便与 rspec 和 capybara 一起使用,但对于我的生活,我无法让它正常运行。
据我所知,问题在于 nokogiri 使用了错误版本的 libxml2。到目前为止,我已经尝试使用 Homebrew 卸载和重新安装 libxml2(确保它是最新的),使用 bundle 卸载和重新安装 nokogiri,并指定 Homebrew 在安装 nokogiri gem 时安装的 libxml2 文件的确切路径。我最近的安装说明是这样的
sudo gem install nokogiri -- --with-xml2-include=/usr/local/Cellar/libxml2/2.9.0/include/libxml2 --with-xml2-lib=/usr/local/Cellar/libxml2/2.9.0/lib --with-xslt-dir=/usr/local/Cellar/libxslt/1.1.28
所有这些位置都正确对应于安装工具的位置。然而,在运行bundle exec rspec spec/requests/static_pages.rb 时,我仍然得到这个输出:
/Users/alex/.rvm/gems/ruby-1.9.3-p286/gems/nokogiri-1.5.9/lib/nokogiri.rb:28:in `require': dlopen(/Users/alex/.rvm/gems/ruby-1.9.3-p286/gems/nokogiri-1.5.9/lib/nokogiri/nokogiri.bundle, 9): Library not loaded: /usr/local/lib/libxml2.2.dylib (LoadError)

我已经尝试了我在网上找到的所有步骤(大多数参考构建和加载不同版本的 libxml2,例如 this one,但还没有成功。我的 Gemfile 和 Gemfile.lock 可以在 @987654322 找到@. 如果有人可以帮助我,我将不胜感激。我无法在网上找到任何其他有此问题的案例。
【问题讨论】:
-
brew --prefix libxml2的输出是什么?请参阅 nokogiri/ext/nokogiri/ 中的 extconf.rb 文件以获取有关 Nokogiri 在何处查找库和头文件的线索。 -
这是输出:/usr/local/opt/libxml2 我找到了您所指的文件,我想我明白这一切的含义,尽管我真的不确定。我应该将 Homebrew 的路径添加到要检查的位置列表吗?如果我这样做,是否会停止使用旧的错误版本的 libxml2?
-
太棒了!那行得通!我之前尝试过这些步骤,除了最后一个。我还使用了 Macports 而不是 Homebrew——也许这有帮助。不管怎样,它做到了。非常感谢!

alexlafroscia 那么解决方案是什么?请将答案标记为已接受。
