Nokogiri安装在Elastic Beanstalk上失败
我试图用AWS Elastic Beanstalk部署我的Rails应用程序。 我已经创建了实例，但是当我尝试使用aws.push部署应用程序时，我在事件日志中遇到以下错误：
2014-09-22 01:23:40 UTC+0550 ERROR [Instance: i-744edb4a Module: AWSEBAutoScalingGroup ConfigSet: null] Command failed on instance. Return code: 1 Output: Error occurred during build: Command hooks failed . 2014-09-22 01:23:39 UTC+0550 ERROR Script /opt/elasticbeanstalk/hooks/appdeploy/pre/10_bundle_install.sh failed with returncode 5
我拉了日志，发现nokogiri gem的安装失败并出现错误：

Nokogiri builds and uses a packaged version of libxml2. If this is a concern for you and you want to use the system library instead, abort this installation process and reinstall nokogiri as follows: gem install nokogiri -- --use-system-libraries If you are using Bundler, tell it to use the option: bundle config build.nokogiri --use-system-libraries bundle install However, note that nokogiri does not necessarily support all versions of libxml2. For example, libxml2-2.9.0 and higher are currently known to be broken and thus unsupported by nokogiri, due to compatibility problems and XPath optimization bugs. ************************************************************************ Extracting libxml2-2.8.0.tar.gz into tmp/x86_64-redhat-linux-gnu/ports/libxml2/2.8.0...

我已将以下内容添加到.ebextensions/packages.conf文件中：
packages: yum: postgresql-devel: [] git: [] gcc: [] libxml2: [] libxml2-devel: [] libxslt: [] libxslt-devel: []
我需要做任何其他事情才能安装nokogiri吗？ 我错过了什么吗？
谢谢！
我能够通过在要安装的软件包列表中包含patch来解决这个问题:)
像这样：
packages: yum: postgresql-devel: [] git: [] patch: []
nokogiri有时无法编译的另一个原因是它在低内存机器上耗尽了内存。
Nokogiri需要libxml2和libxslt。 在运行gem install nokogiri或bundle install之前，请确保已安装两者。
即ubuntu服务器将使用apt-get或aptitude安装这些服务器
