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:

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。
