Azure Pipelines 中是否有“/home/vsts”的预定义变量？

Question

我需要将文件缓存在/home/vsts/.cache/torch/.

主文件夹是否有预定义变量？

Answer 1

不，不存在这样的变量。/home/vsts/work您可以使用路径和缓存之一$(System.WorkFolder)/../.cache/torch/。

Ubuntu 代理的预定义变量值：

Answer 2

如果“预定义变量”是指文档中指定的变量之一，则不是。

但是，如果您使用托管 Linux 代理，您可以简单地查看环境变量$HOME，该变量至少在您使用脚本时有效：它可能适合也可能不适合您的用例。

例子：

trigger:
- main

pool:
  vmImage: ubuntu-latest

steps:
  - script: echo $HOME

脚本任务的输出是/home/vsts
