Unzip without .zip extension using PowerShell

Problem

In powershell 5.1, the Expand-Archive cmdlet does not support unzipping files without the .zip extension.

So when you use some github action like this one, you will get an error like this:

install perl github Expand-Archive : is not a supported archive file format. .zip

Solution

You need to install and use new version of powershell, like 7.1.3.

And in your github action you need to add this step:

shell: pwsh

pwsh is the command to use powershell 7.1.3. You will keep using powershell 5.1 when you write powershell.
