Amazon web services Codedeploy部署在BeforeInstall事件中失败，错误为“；退出：0:需要数字参数"；

我的appspec文件中有以下内容（yaml已验证）——

在安装前步骤中，我间歇性地出现以下错误：

Error Code ScriptFailed
Script Name beforeInstall.sh
Message Script at specified location: beforeInstall.sh failed with exit code 255
Log Tail

LifecycleEvent - BeforeInstall
Script - beforeInstall.sh
[stderr]/opt/codedeploy-agent/deployment-root/edbe4bd2-3999-4820-b782-42d8aceb18e6/d-4GJ8QS9MG/deployment-archive/beforeInstall.sh: line 1: exit: 0
: numeric argument required

以下是我的beforeInstall.sh文件的内容-

exit 0

请注意，构建会间歇性地成功。我尝试了以下方法-

• 正在执行beforeInstall.sh文件的dos2unix。运行build并在一些试验后成功（不是在更改后立即），因此不能说这是原因

• 使用zip文件的新名称将新zip上载到S3（只是为了避免在ec2实例上发生任何缓存）

此外，我发现即使构建成功，实例中也没有发生文件部分中提到的文件更改—没有添加要添加的文件，也没有进行文件修改。然而，一些现有文件的时间戳被修改到今天。奇怪

更新

以下是beforeInstall.sh中的

/var/log/aws/codedeploy agent/codedeploy agent.log
