Azure Devops Pipelines - pipeline not see cached NPM - SFDX command

Question

Hello i tried to use SFDX in azure devops pipeline and use a cached npm (sfdx + plugins) from this solution https://learn.microsoft.com/en-us/azure/devops/pipelines/release/caching?view=azure-devops

But after cache reuse and try to install there is no command available. And got error when running pipeline about command not found

I can install this using npm install sfdx-cli but this cost more pipeline minutes so i tried to limit that

Here is a error which i got when use a cached npm : /home/vsts/work/_temp/0ffaa6e5-b953-41a4-a173-5ce1ba6b11f3.sh: line 1: sfdx: command not found

i tried use a npm ci --config $(npm_config_cache) --loglevel verbose but this is not working too :( Here is sample pipeline which im using:

jobs:
- job: Validate
  displayName: Validate
  pool:
    vmImage: 'ubuntu-latest'

  variables:
    npm_config_cache: $(Pipeline.Workspace)/.npm
  steps:
  - task: DownloadSecureFile@1
    name: SalesforceToken
    displayName: 'Download auth file for SFDX'
    inputs:
      secureFile: ${{ parameters.tokenName }}
  - task: Cache@2
    inputs:
      key: 'npm | "$(Agent.OS)" | ./package-lock.json'
      restoreKeys: |
        npm | "$(Agent.OS)"
      path: $(npm_config_cache)
    displayName: "Cache npm"
  - task: Npm@1
    inputs:
      command: 'install'
      workingDir: '.'

  - script: |
      if ! command -v sfdx &> /dev/null
        then
            exit 0
        else
            echo "SFDX installed."
      fi
