AWS 和 Ruby Stack - 弹性 beantalk 部署上出现错误

Question

我有一个使用 AWS Elastic Beanstalk 配置的 Ruby Stack。上周，我的所有部署都正常，但由于我尝试将 MySQL RDS DB 更改为使用 UTF-8，所以每次运行 eb deploy 时都会遇到这个问题：

INFO: Environment update is starting.                               
INFO: Deploying new version to instance(s).                           
ERROR: UnicodeEncodeError :: 'ascii' codec can't encode character u'\u2018' in position 90: ordinal not in range(128)

当我检查 AWS EB 界面时，我收到了以下错误消息：

[Instance: i-2a4575cc] Command failed on instance. Return code: 1 Output: cp: cannot stat ‘/var/tmp/backup/10_bundle_install.sh’: No such file or directory. Hook /opt/elasticbeanstalk/hooks/appdeploy/post/05_revert_bundle_install_local.sh failed. For more detail, check /var/log/eb-activity.log using console or EB CLI.

最后，我检查了上面提到的 /var/log/eb-activity.log，最后几行如下：

[2015-06-16T09:03:39.079Z] INFO  [23525] - [CMD-AppDeploy/AppDeployStage1/AppDeployEnactHook] : Completed activity. Result:

  Command CMD-AppDeploy failed.

问题似乎来自 05_revert_bundle_install_local.sh 脚本中请求的cp 命令：

cp -a /var/tmp/backup/10_bundle_install.sh /opt/elasticbeanstalk/hooks/appdeploy/pre/10_bundle_install.sh

/var/tmp/backup/10_bundle_install.sh 不存在。

你知道会发生什么吗？以及如何解决它以避免错误消息并进行干净的部署？

谢谢！

看看here。

显然在安装默认示例应用程序时，beantalk 也会安装此文件并“忘记”删除它。所以解决方法就是手动删除。
