error appear when installing IBM Cloud CLI "'iex' is not recognized as an internal or external command..."
I'm trying to install IBM Cloud CLI but there is a problem faced me when I do this.
I added the Path to environment variables but it didn't work too !
This happens because the iex (shorthand for Invoke-Expression) command is a Powershell command, but it is entered to Command prompt. The latter is the old command shell that dates back to the MS-DOS days of the 80's.
One can tell the difference from the fact that the window title bar says Command Prompt, not Powershell. Often - not always! - a Powershell session has blue background and command has black.
To run Powershell commands, start a Powershell session either by typing powershell and pressing enter into a command session, or by opening Windows Start menu and typing powershell (followed by enter).
