不能安装Twilio gem - libxml问题

在尝试在普通脚本和rails应用程序中安装斜纹宝石宝石数小时后，我已经找到了专业人士。不能安装Twilio gem - libxml问题

我得到的错误是“在Gemfile中： twilio，红宝石被解析为5.2.0，这取决于的libxml-红宝石 ”

我尝试安装的libxml的宝石到我的宝石文件和错误“Gem :: Ext :: BuildError：错误：无法构建gem本机扩展”。然后在底部说：“安装libxml-ruby（3.0.0）时发生错误，并且Bundler无法继续。请确保gem install libxml-ruby -v '3.0.0'在绑定之前成功。”

我使用的rails版本是4.2.4，我的操作系统是MACOS Sierra。下面是我尝试用twilio gem捆绑安装时的整个输出。我读了几篇关于Stack的文章，但目前为止没有任何帮助：

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

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

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.

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

我有Mac系统Sierra和之前没有安装Twilio宝石。我做了'gem list'，可以看到我安装了'libxml-ruby（2.6.0）'。我运行'sudo gem install twilio-ruby'，它安装了Twilio 5.2.0 gem ok。我的主文件夹中没有'.rvm'目录。我想知道你是否可以尝试删除该版本并回到“本地”版本？对不起，这不是太大的帮助！ – Andy

我最终安装了4.11版本，一切都很简单。谢谢。你是男人 –

我找到了一个解决方案！（在Debian 9运行）

sudo apt-get install -y libxml2-dev 

gem install libxml-ruby -v '3.0.0' 

bundle install

好像用的libxml-红宝石尝试使用libxml2的问题
