这是我在“安装”步骤中遇到的错误-

File already exists at location /var/cake_1.2.0.6311-beta/app/webroot/../../somefile.php

我无法总结这一情况的发展过程。但我记得的是-

我通过jenkins (代码部署插件集成)启动了一个部署。部署在“安装”步骤中失败，我粘贴了上面的错误。注-这是appspec.yml文件文件部分中的第一个文件。
据我所知，我在同一个部署组上做了一些部署，直接通过代码部署(很可能使用Jenkins在上面一步中创建的相同的S3文件)，并且已经成功了。

- I then had several failed deployments (deliberately failed at various steps, e.g. beforeInstall by exiting with a non zero number).

此后，我甚至无法通过代码部署直接获得任何成功的部署。

背景

我检查了出现关联的这个问题，并尝试删除了/opt/codedeploy-agent/deployment-root/中的所有内容，就像在答案之一中提到的那样，但是它导致了在我的实例中被破坏的代码部署，并且部署via Jenkins开始抛出这个错误，因为它试图查找最后一次成功的部署(它似乎被删除了)-

Jenkins触发的代码部署在ApplicationStop步骤中失败，尽管同一部署组通过直接代码部署正在成功运行。

然后，我在实例上重新安装了代码部署，上面提到的步骤就是我之后所做的工作。

更新-打开Bounty

正如Rodrigo M所回答的，从实例上的部署路径中删除这样的文件到目前为止对我是有效的，但是对于这个特定的文件来说也是一样的-

 File already exists at location /var/cake_1.2.0.6311-beta/deployment/serverLoad.json

我核实了以下情况-

在从上述所有实例的位置删除文件后，我进行了新的部署。我注意到文件重新出现，但仍然抛出了上面提到的相同的错误，部署失败。
在不删除的情况下，我将文件修改为777。同样的结果。

有趣的是，昨天我得到了多个文件的这个错误，当我找到它们并进行了一个新的构建时，我开始逐个删除它们。除了这一个文件之外，所有其他文件的问题都得到了解决，即使删除也不起作用。毫无线索!

注意:我现在所做的所有部署都是由Jenkins触发的(没有通过AWS代码部署触发的直接部署)。

下面是来自/var/log/aws/codedeploy-agent/codedeploy-agent.log的日志跟踪，其中包含相关的错误堆栈strace -
