为什么我在触发构建管道时出现错误？在默认池中找不到满足指定要求的代理？

Question

我正在 Azure DevOps CICD 管道中工作。我在默认池中创建了一个代理，它是一个自托管代理。

我的代理详细信息：

代理.名称：部署代理 代理版本：2.210.1

下面是我的yaml文件：

trigger: none

variables:
- name: solution
  value: 'MyApp.sln'
- name: buildPlatform
  value: 'Any CPU'
- name: buildConfiguration
  value: 'Release'
- name: "npm_config_cache"
  value: $(Pipeline.Workspace)/.npm

          az --version
          az account show
          az vm deallocate --name MyDeployment-Agent --no-wait --resource-group MyDeployment

但是，即使我的代理已启用并运行，我也会收到以下错误。

#Error: 在默认池中找不到满足指定要求的代理：Use_for -equals Deployment-Agent, npm, Agent.Version -gtVersion 2.182.1

我可以知道它是否采用 2.182.1 作为版本，因为我的代理版本高于此版本，但仍然采用以前的版本并给我错误？由于我是 azure CICD 的新手，有人可以帮我吗？

Answer 1

根据错误信息，请尝试以下步骤：

1. 检查代理中“Use_for”的用户能力。
2. 在代理中安装 NPM，然后重新启动代理以扫描 NPM。

更多信息，您可以参考：https://learn.microsoft.com/en-us/azure/devops/pipelines/process/demands?view=azure-devops&tabs=yaml

并安装 NPM：https://docs.npmjs.com/downloading-and-installing-node-js-and-npm

添加第一个任务：

  - task: NodeTool@0
    displayName: Installing Node.JS  
    inputs:
      versionSpec: '16.x'
