Unable to run project under Gulp

Question

I'm new to front-end development and I have some existing project which I unable to run.

Documentation says, to run the project I should execute:

$ gulp && gulp serve

However, I receive the following error:

/home/alex/some/project/node_modules/@types/gulp/index.d.ts(15,15): error TS2430: Interface 'Gulp' incorrectly extends interface 'Orchestrator'.
  Types of property 'task' are incompatible.
    Type 'AddMethod' is not assignable to type '{ (name: string): Task; (name: string, fn: TaskFunc): void; (name: string, dep: string[], fn: Tas...'.
      Type 'Orchestrator' is not assignable to type 'Task'.
        Property 'fn' is missing in type 'Orchestrator'.

What did I miss?

        port: 8000,

            },
            cors: true,
            middleware: function(req, res, next) {
                res.setHeader("Access-Control-Allow-Origin", "*");
                res.setHeader("Access-Control-Allow-Headers", "*");
                next();
            }
        }

    gulp.watch(config.allcss, ["styles"]);

    gulp.watch(config.alljade, ["jade-watch"]);
    gulp.watch(config.allts, ["ts-watch"]);
