Seriously - you have to be willing to be helped. If you post it like this, it's almost unreadable. I went through this myself to structure your code, so we can actually see what's going on there:

<?php 
  use Illuminate\Support\Facades\Schema; 
  use Illuminate\Database\Schema\Blueprint; 
  use Illuminate\Database\Migrations\Migration; 

  class CreateUsersTable extends Migration { 
    /** 
     * Run the migrations. 
     * 
     * @return void 
    */ 
    public function up() { 
      Schema::create('users', function (Blueprint $table) { 
        $table->increments('id'); 
        $table->string('usuario', 50); 
        $table->string('password', 50); 
        $table->string('nombre', 50); 
        $table->string('apellido', 50); 
        $table->string('departamento', 50); 
        $table->string('puesto', 50); 
        $table->string('correo_electronico', 50); 
        $table->rememberToken(); 
        $table->timestamps(); 
      }); 
    } 
    /** 
     * Reverse the migrations. 
     * 
     * @return void 
     */ 
    public function down() { 
      Schema::dropIfExists('users'); 
    } 
  }

I don't see an issue with that code either - are you sure this is what the parser is complaining about?
