azure-devops - Azure Powershell - Az 模块在 Ubuntu 托管的构建代理上不起作用

Question

我有一个在 Ubuntu 16.04 托管构建代理上运行在 Azure DevOps 中的构建。我正在使用最新版本的“Azure Powershell”任务（版本 4.* 预览版），它应该是多平台的，支持 Powershell 核心，并支持使用Azure Powershell Az 模块。

但是，它并不完全奏效。在运行我的任何脚本之前，它会出错：

Az Powershell 模块似乎在 Windows VS2017 托管代理上正常工作/加载，但在 Ubuntu 上没有运气。有关解决此问题的任何建议吗？

通过添加在构建代理上安装 Az Powershell 模块的先前构建步骤，我能够让 Az Powershell 在 Ubuntu 代理上的 Azure DevOps 构建中工作。

我添加了一个 powershell 脚本来安装 Az 模块和卸载 Azure-Rm 模块；我从命令行任务中调用它，这样我就可以将它包装起来，sudo使其成为全局更改。

这是命令行任务（YAML）：

steps:
- displayName: 'Install Az Powershell Modules'
  script: |
   sudo /usr/bin/pwsh -NoLogo -NoProfile -NonInteractive -ExecutionPolicy Unrestricted -File "$(Build.Repository.LocalPath)/build/install-az-modules.ps1" 

这是build/install-az-modules.ps1脚本：

<#
.SYNOPSIS
    Build agent script to install Az Powershell modules. This script should be run as sudo.

    On a linux build agent, this command can be run as:
    sudo /usr/bin/pwsh -NoLogo -NoProfile -NonInteractive -Command . '$(Build.Repository.LocalPath)/build/install-az-modules.ps1'
#>

# Disable status info to clean up build agent stdout
$global:ProgressPreference = 'SilentlyContinue'
$global:VerbosePreference = "SilentlyContinue"

$azureRmModule = Get-InstalledModule AzureRM -ErrorAction SilentlyContinue
if ($azureRmModule) {
  Write-Host 'AzureRM module exists. Removing it'
  Uninstall-Module -Name AzureRM -AllVersions
  Write-Host 'AzureRM module removed'
}

Write-Host 'Installing Az module...'
Install-Module Az -Force -AllowClobber

if (Get-Command Uninstall-AzureRm -ErrorAction SilentlyContinue) {
  Write-Host 'Running Uninstall-AzureRm...'
  Uninstall-AzureRm
}
