Expected behavior Gulp should start and run live server etc after installation. Actual behavior throws error: gulp.start is not a function. I did installation step by step with gulp instructions and double checked it. I don't know if thats the case but when i used MDB with gulp 3.. it workes like a charm. Now i see it proceeded to 4 and maybe thats the case? What can i do with it? Resources (screenshots, code snippets etc.) here's the error. When i comment 104 line, another error throws for scss etc...
