You can use cmder instead of cmd in Webstorm

This is far better option that the actual cmd.

Notes :

There is a problem when the cmd is opened.
Occurs only when the project is on another disk.
The path is not the one of your current project.
You should always cd to set the correct path.

Change the cmd path in Webstorm

In your Webstorm terminal settings, use "cmd.exe" /k ""%CMDER_ROOT%\vendor\init.bat"" as the Shell path.
The double-double-quotes are intentional, as they counteract the missing double quotes in the environment variable.
