Ruby on rails Bundler赢得'；t安装libxml-ruby（2.2.2）Rails

我正在尝试安装一个有点过时的Rails应用程序，这样我就可以尝试更新它一点，但我似乎无法让捆绑安装正常工作。它一直在告诉我：

An error occurred while installing libxml-ruby (2.2.2), and Bundler cannot continue.
Make sure that `gem install libxml-ruby -v '2.2.2'` succeeds before bundling.

整个错误是：

Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

但是当我使用bundle安装时，同样的错误再次发生

当我尝试

gem install libxml-ruby -v '2.2.2'

我得到这个错误：

谢谢

这看起来很像libxml ruby。您系统上的libxml2版本可能太新，无法与您尝试安装的libxmlruby版本配合使用。我同意我系统上的libxml2版本似乎太新，无法与我尝试安装的版本配合使用，但我不知道如何强制我的系统使用旧版本…我尝试了链接中的内容您发送了，但没有改变任何内容……您可以将Rails项目升级到libxml ruby 2.4.0（修复此问题的版本）吗？看起来2.2.2和2.4.0之间没有任何中断。谢谢@PhilRoss，这解决了问题
