Azure devops Azure Powershell-Az模块在Ubuntu托管的构建代理上不工作

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

然而，这并不完全有效。在运行任何脚本之前，它会出现以下错误：

Az Powershell模块似乎在Windows VS2017托管代理上正常工作/加载，但在Ubuntu上没有成功。有关于修复此问题的建议吗？

通过添加先前的构建步骤，在构建代理上安装Az Powershell模块，我可以在Ubuntu代理上的Azure DevOps构建中使用Az Powershell

我添加了一个powershell脚本来安装Az模块并卸载Azure Rm模块；我从一个网站上调用它，这样我就可以把它包装在sudo中，让它成为一个全球性的变化

以下是命令行任务（YAML）：

下面是

构建/安装az模块.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
}

#禁用状态信息以清除生成代理标准输出
$global:ProgressPreference='SilentlyContinue'
$global:VerbosePreference=“SilentlyContinue”
$AzureRM模块=获取安装模块AzureRM-ErrorAction SilentlyContinue
如果（$azureRmModule）{
写入主机“AzureRM模块存在。正在删除”
卸载模块-名称AzureRM-所有版本
写入主机“AzureRM模块已删除”
}
写入主机“安装Az模块…”
安装模块Az-Force-AllowClobber
if（Get命令Uninstall AzureRm-ErrorAction SilentlyContinue）{
写入主机“正在运行卸载AzureRm…”
卸载AzureRm
}

相关，但与此特定问题无关（不使用Ubuntu）
