Azure DevOps CI代理商错误时，请安装NPM

Question

我为Angular 13 Web应用程序配置了Azure Devops CI管道。节点版本为14.17 NPM 6.14.13使用了Azure代理Ubuntu 20.04 LTS。在下面，您可以看到我构建的

resources:
  repositories:
  - repository: self
    type: git
    ref: refs/heads/development
jobs:
- job: Job_1
  displayName: Agent job 1
  pool:
    vmImage: ubuntu-20.04
  steps:
  - checkout: self
  - task: NodeTool@0
    displayName: Use Node 14.17.x
    inputs:
      versionSpec: 14.17.x
  - task: CmdLine@2
    displayName: Install Anguler
    inputs:
      script: npm install -g @angular/cli
  - task: Npm@1
    displayName: npm install
    inputs:

  - task: CmdLine@1
    displayName: Run ng
    inputs:

      arguments: build
  - task: PublishBuildArtifacts@1
    displayName: 'Publish Artifact: dist'
    inputs:
      PathtoPublish: dist
      ArtifactName: dist 

问题是 npm install 在Errror之后返回时，

有人可以帮助我吗？

这与Azure Devops CI管道本身无关。您遇到 https://nodejs.org/en/blog/blog/npm/peer - 依赖性。总而言之，上游软件包依赖于托管应用程序下游安装的支持软件包，并且版本可以非常限制。解决方法（根据错误消息）是使用npm install -legacy-peer-deps https://docs.npmjs.com/cli/v7/usise-npm/config#legacy-peer-deps 。您可以通过使用命令npm info ng-select2 peerDepentencies或特定版本npm info [email＆nbsp; prectioned] peerDependendencencies。

下面的结果。请注意，代码> select2@^4.0.x。

您是否已安装select2@^4.0.x？

{
  '@angular/common': '^13.0.0',
  '@angular/core': '^13.0.0',
  '@types/jquery': '3.5.x',
  '@types/select2': '^4.0.x',
  select2: '^4.0.x',
  jquery: '3.5.x'
}

安装npm的正确版本安装select2@^4.0.0应该解决您的问题。

在您的package.json中：

"select2": "^4.0.0"
