我试图用AWS Elastic Beanstalk部署我的Rails应用程序。我创建了实例，但是当我尝试使用aws.push部署应用程序时，我在事件日志中收到以下错误：
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：

************************************************************************
IMPORTANT! 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.

我已将以下内容添加到文件.ebextensions/packages.conf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。
即一个ubuntu服务器将使用apt-get或aptitude安装这些服务器
