Powershell - command was found in the module, but the module could not be loaded

Question

I am using let's encrypt certificate and azure key vault to automate renewal process using this repo: https://github.com/brent-robinson/posh-acme-azure-example

I have installed the module Az.KeyVault using yaml on azure devops pipeline:

# Install the Az PowerShell modules our script will need
- task: PowerShell@2
  displayName: Install PowerShell Modules (Az.Accounts, Az.KeyVault, Az.Resources, Posh-ACME)
  inputs:
    targetType: 'inline'
    script: 'Install-Module Az.Accounts, Az.KeyVault, Az.Resources, Posh-ACME -Force'
    errorActionPreference: 'stop'
    failOnStderr: true
    pwsh: true

But, when I run the script, getting the below error:

The 'Get-AzKeyVaultCertificate' command was found in the
     | module 'Az.KeyVault', but the module could not be loaded. For
     | more information, run 'Import-Module Az.KeyVault'.

When I try to add the import module (Import-Module -Name Az.KeyVault -Force) it's giving the below error:

Assembly with the same name is already loaded

This means that there's an assembly version conflict, i.e. a different version of an assembly that the `Az.KeyVault` module is trying to load has already been loaded into the session. — mklement0, Sep 07 '22 at 21:39
@mklement0 how can I make it right? I didn't mention the version while installing the module so it should always install the latest one. right? What do you mean by assembly version? — RNK, Sep 07 '22 at 21:53
The `Az.KeyVault` probably comes _bundled_ with the assemblies it needs. .NET assemblies are versioned (they have an embedded version number). PowerShell (Core) categorically prevents loading a _different_ version of a given assembly into a session - see [this answer](https://stackoverflow.com/a/72509967/45375). You'll need to find out which assembly/ies, specifically, cause the conflict (I have no simple answer). — mklement0, Sep 07 '22 at 22:15

There is an issue with the latest version of Posh-ACME module (4.15.0). Install version 4.14.0 to resolve this.

Install-Module -Name Posh-ACME -RequiredVersion 4.14.0 -Force

When you try to install the module in CI/CD pipeline you can specify the user so that it won't conflict with other.

#install Az PowerShell Modules with Specific User
- task: PowerShell@2
  displayName: Install PowerShell Modules (Az.Accounts, Az.KeyVault, Az.Resources, Posh-ACME)
  inputs:
    targetType: 'inline'
    script: 'Install-Module Az.Accounts, Az.KeyVault, Az.Resources, Posh-ACME -Force CurrentUser'

The 'Get-AzKeyVaultCertificate' command was found in the | module 'Az.KeyVault', but the module could not be loaded. For | more information, run 'Import-Module Az.KeyVault'.

Assembly with the same name is already loaded

The error messages show that Az keyVault was already installed but not able to load in a pipeline to run task. You can specify the user(Current user or all user) to install the required module to specific user and import the required module.

Still getting the same error on importing the module. I tried installing modules using `-Scope CurrentUser` — RNK, Sep 09 '22 at 15:08
