我一直在尝试在我的计算机(Mountain Lion)上安装 Nokogiri 以与 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。但是,在运行时bundle exec rspec spec/requests/static_pages.rb,我仍然得到以下输出:

/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,比如这个,但还没有成功。我的 Gemfile 和 Gemfile.lock 可以在这里找到。如果有人可以帮忙我完全没有,我真的很感激。我无法在网上找到任何其他有此问题的案例。

在 Mavericks 中,在安装 gem 之前安装库brew并设置对我来说是诀窍。NOKOGIRI_USE_SYSTEM_LIBRARIES=1

总结:

  • 如果以前安装过,请卸载 gem:
    $ gem uninstall nokogiri

  • 使用 Homebrew 安装libxml2libxslt并且libiconv
    $ brew install libxml2 libxslt libiconv

  • 安装 gem 指定要链接的库的路径:
    $ NOKOGIRI_USE_SYSTEM_LIBRARIES=1 gem install nokogiri -- --use-system-libraries --with-iconv-dir="$(brew --prefix libiconv)" --with-xml2-config="$(brew --prefix libxml2)/bin/xml2-config" --with-xslt-config="$(brew --prefix libxslt)/bin/xslt-config"

这有助于我更新 libxml 并正确安装 nokogiri ...

  1. gem 卸载 nokogiri libxml-ruby
  2. 酿造更新
  3. 冲泡卸载libxml2
  4. brew install libxml2 --with-xml2-config
  5. 酿造链接--force libxml2
  6. 冲泡安装 libxslt
  7. 酿造链接--force libxslt
  8. 捆绑配置 build.nokogiri -- --with-xml2-dir=/usr --with-xslt-dir=/opt/local --with-iconv-dir=/opt/local
  9. 捆绑安装

为了清楚起见,Phrogz 的评论帮助了我很多。我按照他链接的说明进行操作,如果 libxml2 是个混蛋怎么办?Nokogiri 的 Github 页面上的页面。我最终使用了 Macports 而不是 Homebrew,我不确定这是否是造成差异的原因(我已经尝试了许多这些步骤),但不管怎样,它现在似乎工作正常。

当我遇到问题时,在升级 OsX 后用谷歌搜索了这个问题:

require': dlopen(/Users/tomi/.rvm/gems/ruby-2.1.1@my-gemset/extensions/x86_64-darwin-12/2.1.0-static/nokogiri-1.5.10/nokogiri/nokogiri.bundle, 9): Library not loaded: /usr/local/opt/libxml2/lib/libxml2.2.dylib (LoadError)

这对我有用

brew uninstall libxml2 libxslt libiconv brew install libxml2 libxslt libiconv
