However gulp 4 is not avai

I wrote a batch file that does the job based on what @demisx answered.

The problem I had was a missing npm config parameter 'prefix', so my global directory was the node binary directory. I am pretty sure this wasn't always the case, but I could (re-)set it running this script from the project root directory:

@ECHO OFF
echo configuring npm
set USERNAME=
set USERPROFILE=C:\Users\%USERNAME%
set APPDATA=%USERPROFILE%\AppData\Roaming
call npm config set prefix %APPDATA%\npm

SET DIR_PROJECT="D:/stuff/plugins/wallpaper_engine/raintime-dev"

echo Uninstall previous Gulp installation and related packages, if any
call npm rm gulp -g
call npm rm gulp-cli -g

echo cd %DIR_PROJECT%
cd /D %DIR_PROJECT%

call npm rm gulp --save-dev
call npm rm gulp --save
call npm rm gulp --save-optional
call npm cache clean

echo Install the latest Gulp CLI tools globally
call npm install gulpjs/gulp-cli -g

echo Install Gulp 4 into your project from 4.0 GitHub branch as dev dependency
rem call npm install gulpjs/gulp#4.0 --save-dev
call npm install gulpjs/gulp --save-dev

echo Check the versions installed.

call gulp -v

pause

The script finally showed this:

[14:59:48] CLI version 2.0.1
[14:59:48] Local version 4.0.0

Hope it helps!
