找不到可执行文件：“bash”

Question

我正在尝试在我的 azure 发布管道中运行 bash 脚本。为此，我使用了 Visual Studio 市场中的一个任务：https://marketplace.visualstudio.com/items?itemName=tsuyoshiushio.shell-exec

它将执行一个sed操作来替换一个值，如下所示：

sed -e "s/##BUILD_ID##/${RELEASE_ARTIFACTS__myapp-EBX_BUILDID}/g" "$(System.DefaultWorkingDirectory)/myapp-ebx-acc-repo/myapp-ebx-acc-current.yaml"

我正在 azure devops 服务器（自托管代理）中运行发布管道

以下是来自 azure 管道的日志：

Answer 1

使用以下命令添加 powershell 任务解决了问题

$path="$(System.DefaultWorkingDirectory)/myapp-ebx-acc-repo/myapp-ebx-acc-current.yaml"

(Get-Content $path) -replace "##BUILD_ID##","$(Release.Artifacts.myapp-ebx.BuildId)" |输出文件 $path 获取内容 $path

Answer 2

如果您在 Azure DevOps 组织中安装此第三个扩展：Shell exec task without file，则此外部任务：Shell Exec 现在在 Azure 管道中可用。

但是，您提供的日志显示您正在使用此系统预定义的Bash task，请检查您是否正在使用目标任务来运行此 bash 脚本。
