I've probably used gulp in 6 other projects and the install and use of it never was a problem.
I'm running Mendix 7.02. As you can see in the pictures, the installation was a few warning, gulp recognizes changes and the browerser:3000 is launced. However, when i change files, the CSS and sass files are not generated. I've tried to use gulp on another machine with the same project but the results are the same. What is the problem or how can I debug to find the problem? The only strange thing that I noticed is that there is no lib folder created under theme/styles/sass
