Question

由于捆绑安装错误，我无法将我的rails应用程序部署到弹性beanstalk。这是完整的日志：

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

      /opt/rubies/ruby-2.1.5/bin/ruby extconf.rb 
  checking for sasl/sasl.h... no
  Please install SASL to continue. The package is called libsasl2-dev on Ubuntu and cyrus-sasl on Gentoo.
  *** extconf.rb failed ***
  Could not create Makefile due to some reason, probably lack of necessary
  libraries and/or headers.  Check the mkmf.log file for more details.  You may
  need configuration options.

  Provided configuration options:
    --with-opt-dir
    --without-opt-dir
    --with-opt-include
    --without-opt-include=${opt-dir}/include

    --without-make-prog

  extconf failed, exit code 1

  Gem files will remain installed in /opt/rubies/ruby-2.1.5/lib/ruby/gems/2.1.0/gems/memcached-1.8.0 for inspection.

  An error occurred while installing memcached (1.8.0), and Bundler cannot
  continue.
  Make sure that `gem install memcached -v '1.8.0'` succeeds before bundling. (Executor::NonZeroExitStatus)

我最近更新了ruby 2.1.5虽然rvm（我之前运行的是ruby 2.0.0），这可能会导致我的问题？

Answer 1

它在运行linux的aws ec2 t1.micro实例
上

假设这是亚马逊的Linux发行版（基于yum的发行版），您可以查看错误消息并获得解决方案。

请安装SASL以继续。该软件包在Ubuntu上被称为libsasl2-dev

对于Ubuntu，你会使用

sudo apt-get install libsasl2-dev

对于您的操作系统，您需要使用yum。不确定确切的包名，但您可以尝试

sudo yum search libsasl

找到libsasl2-dev的一些变体。然后运行

sudo yum install <package name>

Answer 2

由于您使用EB，您是否尝试将libsasl2-dev添加到Elastic Beanstalk配置文件中的包中？

AWS包安装错误：确保`gem install memcached -v＆＃39; 1.8.0＆＃39;`在捆绑之前成功
