【问题描述】：
我是 Ruby 世界的新手，我需要克隆一个现有项目。
说明如下：
source .env.development
bundle install
但它失败了：
Using libv8 3.16.14.15
Fetching libxml-ruby 2.9.0
Installing libxml-ruby 2.9.0 with native extensions
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.

Could not create Makefile due to some reason, probably lack of necessary
libraries and/or headers. Check the mkmf.log file for more details. You may
need configuration options.
Provided configuration options:

extconf failure: need libxml2.
Install the library or try one of the following options to extconf.rb:
--with-xml2-config=/path/to/xml2-config
--with-xml2-dir=/path/to/libxml2
--with-xml2-lib=/path/to/libxml2/lib
--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:
/Users/vlad/.rvm/gems/ruby-2.3.1/extensions/x86_64-darwin-18/2.3.0/libxml-ruby-2.9.0/mkmf.log
extconf failed, exit code 1
Gem files will remain installed in /Users/vlad/.rvm/gems/ruby-2.3.1/gems/libxml-ruby-2.9.0 for inspection.
Results logged to /Users/vlad/.rvm/gems/ruby-2.3.1/extensions/x86_64-darwin-18/2.3.0/libxml-ruby-2.9.0/gem_make.out
An error occurred while installing libxml-ruby (2.9.0), and Bundler cannot continue.
Make sure that `gem install libxml-ruby -v '2.9.0'` succeeds before bundling.
In Gemfile:
upnxt_community_lib_common was resolved to 1.7.49, which depends on
upnxt_processing_lib_document was resolved to 2.0.0, which depends on
libxml-
如果我想执行建议的命令“gem install libxml-ruby -v '2.9.0'”，我会得到同样的错误。
操作系统：MacOS Mojave，版本 10.14。 项目所需的 Ruby 版本：ruby 2.3.1p112 (2016-04-26 revision 54768) [x86_64-darwin18]
我也尝试了this，但没有帮助。
提前感谢您的帮助！
【问题讨论】：
-
brew install libxml2? -
如果仍然失败，
brew link --force libxml2? -
@TomLord，我试过了，没用
-
@NicuVlad 它仍然说 “需要 libxml2”？
-
@NicuVlad 当我们从建议中听到的只是“没有帮助”或“没有用”时，很难诊断问题。错误消息是否保持不变，还是发生了变化？如果错误发生了变化，那么我们可能已经取得了一些进展，现在需要解决一个不同的问题。
