How to update Azure PowerShell?

Question

I have Azure PowerShell 1.0.3 installed via the Gallery (per the instructions here in the Installing Azure PowerShell From The Gallery section). I want to update to the latest version but am unclear on the commands that I need to run. I tried the following, but decided to ask rather than potentially corrupt my installation:

PS C:\Windows\system32> Install-Module AzureRM

You are installing the module(s) from an untrusted repository. If you trust this repository, change its
InstallationPolicy value by running the Set-PSRepository cmdlet.
Are you sure you want to install software from 'https://www.powershellgallery.com/api/v2/'?
[Y] Yes  [A] Yes to All  [N] No  [L] No to All  [S] Suspend  [?] Help (default is "N"): y
WARNING: Version '1.0.3' of module 'AzureRM' is already installed at 'C:\Program
Files\WindowsPowerShell\Modules\AzureRM\1.0.3'. To delete version '1.0.3' and install version '1.1.0', run
Install-Module, and add the -Force parameter.

Can someone provide a script to update Azure PowerShell?

Answer 1

The command you need to run is in the help text you posted. Use Install-Module -Force AzureRM. See the -Force tag.

Once you've updated the bootstrapper, run Install-AzureRM to install the new packages.

Edit for updated (WMF > 4) PowerShell:

PowerShell has an Update-Module AzureRM function that will perform similar activity as Install-Module -Force AzureRM. You may also want to use the -AllowClobber argument on Install-Module if you have functions already defined in your local environment that the AzureRM would overwrite.

However, neither will update your current environment, so prior to running Install-AzureRM, check to see that you've loaded the latest AzureRM module. For example, if you wanted to update from 1.0.1 to 1.0.3:

$ Get-Module AzureRM

ModuleType Version    Name         ExportedCommands
---------- -------    ----         ----------------
Script     1.0.1      AzureRM      {...}

$ Update-Module AzureRM

$ # This will still be old because we haven't imported the newer version.
$ (Get-Module AzureRM).Version.ToString() 
1.0.1

$ Remove-Module AzureRM
$ Import-Module AzureRM
$ (Get-Module AzureRM).Version.ToString() 
1.0.3

$ Install-AzureRM

Or you can just open a new PowerShell window after running the update.
