Question

在尝试在常规脚本和rails应用程序中安装twill-ruby gem之后遇到了数小时的麻烦，我来到了专业人士。

我得到的错误是＆＃34;在Gemfile中： twilio-ruby被解决为5.2.0，这取决于 libxml的旁注＆＃34;

我尝试将libxml gem安装到我的gem文件中，并且错误＆＃34; Gem :: Ext :: BuildError：错误：无法构建gem原生扩展。＆＃34;然后在底部它说＆＃34;安装libxml-ruby（3.0.0）时发生错误，Bundler无法继续。在捆绑之前确保gem install libxml-ruby -v '3.0.0'成功。＆＃34;

我使用的导轨版本是4.2.4，我的操作系统是MACOS Sierra。当我尝试使用twilio gem捆绑安装时的整个输出如下。我已经在Stack上阅读了一些文章但到目前为止没有任何帮助：

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-lib=/path/to/libxml2/lib

To see why this extension failed to compile, please check the mkmf.log which can be found here:

  /Users/jameshart/.rvm/gems/ruby-2.3.0/extensions/x86_64-darwin-16/2.3.0/libxml-ruby-3.0.0/mkmf.log

extconf failed, exit code 1

Gem files will remain installed in /Users/jameshart/.rvm/gems/ruby-2.3.0/gems/libxml-ruby-3.0.0 for inspection.
Results logged to /Users/jameshart/.rvm/gems/ruby-2.3.0/extensions/x86_64-darwin-16/2.3.0/libxml-ruby-3.0.0/gem_make.out

An error occurred while installing libxml-ruby (3.0.0), and Bundler cannot continue.
Make sure that `gem install libxml-ruby -v '3.0.0'` succeeds before bundling.

In Gemfile:
  twilio-ruby was resolved to 5.2.0, which depends on
    libxml-ruby

Answer 1

我找到了解决方案！（在Debian 9上运行）

sudo apt-get install -y libxml2-dev

gem install libxml-ruby -v '3.0.0' 

bundle install

似乎是libxml-ruby试图使用libxml2

的问题

无法安装Twilio gem - libxml问题
