##[error]Script failed with error: Error: Unable to locate executable file: ‘pwsh’.

In AzureCLI@2 you may choose from a variety of options when it comes on how this task will be executed on the agent machine. I usually choose powershell for windows machines and powershell core for Unix based machines (pwsh).

Recently I got an error on a Windows machine when using Powershell core. The latest version of powershell which is currently on 7.* version can be used as pscore in the AzureCLI@2 task.

      - task: AzureCLI@2
        displayName: az cli task
        inputs:
          azureSubscription: 'SERVICE-CONNECTION'
          scriptType: 'pscore'
          scriptLocation: 'inlineScript'
          inlineScript: |
           script

Error message:

##[error]Script failed with error: Error: Unable to locate executable file: ‘pwsh’. Please verify either the file path exists or the file can be found within a directory specified by the PATH environment variable. Also verify the file has a valid extension for an executable file.

Solution:

In order to bypass this problem you should make sure that the latest version of powershell which is multiplatform should be installed on your system. At the time of this article this version is 7.*

After installing powershell you should make a restart also on the machine in order for the environmental variables to be added on PATH. Then you can execute your pwsh tasks on your agent machines.
