当尝试捆绑安装时，它无法安装libxml-ruby？

Question

我在本地设置项目时遇到了问题。我正在尝试运行我的rails服务器，但在安装libxml-ruby gem时遇到了问题，无法启动和运行它。如有任何帮助，我们将不胜感激。

当我尝试运行rails s来让服务器运行时。

我得到了这个错误：

Could not find libxml-ruby-3.1.0 in any of the sources
Run bundle install to install missing gems. 

然后，当我捆绑安装时，我得到这个错误：

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

Install the library or try one of the following options to extconf.rb:

  --with-xml2-include=/path/to/libxml2/include
To see why this extension failed to compile, please check the mkmf.log which can be found here:
