ruby-on-rails - 库版本不兼容:nokogiri.bundle需要版本11.0.0或更高版本，但libxml2.2.dylib

Question

尝试在Hartl教程中运行rspec时遇到此错误。我在错误中进行了搜索，但从未针对特定版本进行过修复，而这些修复实际上并不能解决我的问题。

我建议您首先使用以下方法卸载Nokogiri:

sudo gem uninstall nokogiri

然后使用rubygems安装Nokogiri:

gem install nokogiri

如果这不起作用，则在Nokogiri上有一个 open issue支持libxml 2.9.0及更高版本。为准备下一个libxml2版本启动了一个 libxml2-2.9.1 branch。

然后尝试从Gemfile中的该分支中拉出，如下所示:

gem "nokogiri", github: "sparklemotion/nokogiri", branch: "libxml2-2.9.1"

或安装旧版本的libxml2。

如果仍然无法解决问题，您可能还需要尝试以下建议: What to do if libxml2 is being a jerk.
