【问题描述】：

我正在尝试使用 AWS Elastic Beanstalk 部署我的 Rails 应用程序。我已经创建了实例，但当我尝试使用 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

拉取日志发现nokogiri gem 安装失败，报错：

************************************************************************
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：

packages:
  yum:
    postgresql-devel: []
    git: []
    gcc: []
    libxml2: []
    libxml2-devel: []
    libxslt: []
    libxslt-devel: []

安装 nokogiri 是否需要执行其他操作？我错过了什么吗？

谢谢！

【参考方案1】：

Nokogiri 需要 libxml2 和 libxslt。确保在运行 gem install nokogiri 或 bundle install 之前都已安装。

即ubuntu 服务器会使用 apt-get 或 aptitude 安装这些文件

【讨论】：

如果您正确阅读了我的问题并且知道我在问什么，您就会知道我已指示 eb 为我安装这些。还是谢谢/。

我确实阅读了您的问题，但我对 yml 并不熟悉，而且很明显，这些库并没有按照您想要的方式安装。

【参考方案2】：

我能够通过将patch 包含在要安装的软件包列表中来解决此问题:)

像这样：

packages:
  yum:
    postgresql-devel: []
    git: []
    patch: []

【参考方案3】：

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。

【讨论】：

不要尝试在小于 t2.small 的任何东西上运行 ruby​​。
