Ruby on rails Nokogiri安装失败，缺少libxslt

我很抱歉，但我想我尝试了我在互联网上看到的一切，以使其工作，但它总是失败：(

我必须在一个使用ruby 2.1.10的旧rails项目上工作，当我捆绑更新nokogiri'1.6.3.1'构建时失败

它与ruby 2.6.6和nokogiri-1.10.10配合得很好

我已经安装了libxml2和libxsl，并安装了自制xcode，我已经阅读并同意了许可证

我试着安装nokogiri链接

gem install nokogiri-v'1.6.3.1'--使用系统库--with-xml2-include=$（brew--前缀libxml2）/include/libxml2--with xslt include=$（brew--前缀libxslt）/include/libxslt

这就是输出

mkmf.log的输出完全相同。我看到您已经安装了libxml2，也尝试安装libxslt、libxslt-devel，我认为在某个点上还存在对openssl-devel的依赖性。

编辑

Nokogiri有一个关于在MacOS上安装的教程：

你能试试那个文件中的步骤吗

旧信息：

根据：

或者可能：

ln -s /usr/local/opt/libxml2/share/aclocal/libxml.m4 /usr/local/share/aclocal/libxml.m4

---

假设您正在使用MacOs，是否可以尝试以下操作：不，它不起作用：（我有相同的错误消息

libxml2 2.9.0版和更高版本尚不受支持，但仍在继续。

…您的libxml2版本太新了！：（你能试着安装一个旧版本吗？我已经将libxml2降级到2.7.2了。我一直认为libxslt丢失了，但不再有关于libxml2.9.0的警告。现在你已经降级了，你能在我的回答中遵循nokogiri Macos教程吗？我也有同样的错误。你能

ls/usr/local/share/aclocal/

看看还有其他错误吗文件，还有

ls/usr/local/opt/libxml2/share/aclocal/

，看看是否有丢失的xml文件，您可能也想链接这些文件？我编辑了这篇文章，添加了关于ls的新信息。这两个目录在nokogiri网站上用一个更好、更有用的文档更新了我的答案，希望它能提供您需要的步骤谢谢，我已经测试了所有列表，但libxslt总是出现相同的错误：(
