Laravel 5.1 - General error: 1005 Can't create table (mysql)

I'm using laravel to migrate some data, but i'm having this message below:

[Illuminate\Database\QueryException]                                                                                                                                                                
  SQLSTATE[HY000]: General error: 1005 Can't create table 'heinz.#sql-1e83_8' (errno: 150) (SQL: alter table `funcionarios` add constraint funcionarios_supervisor_id_foreign foreign key (`supervis  
  or_id`) references `funcionarios` (`id`))

I tried a lot of thing, but didn't work.

Here is the code of the migration file. (the relevant part).

Schema::create('funcionarios', function (Blueprint $table) {

//            $table->engine = 'InnoDB';

            $table->increments('id');
            $table->string('nome', 60);
            $table->integer('matricula')->unsigned()->unique();
            $table->bigInteger('pis_pasep')->unsigned()->nullable();
            $table->date('data_admissao')->nullable();
            $table->date('data_demissao')->nullable()->default(null);
            $table->date('data_nascimento')->nullable();
            $table->string('apelido', 20)->nullable();
            $table->integer('supervisor_id')->nullable();
            $table->integer('coordenador_id')->nullable();
            $table->integer('gerente_id')->nullable();
            $table->integer('diretor_id')->nullable();
            $table->integer('sexo_id')->nullable();
            $table->integer('setor_id')->nullable();
            $table->integer('cargo_id');
            $table->integer('turno_id')->nullable();
            $table->timestamps();
        });

        Schema::table('funcionarios', function($table){

            $table->foreign('supervisor_id')->references('id')->on('funcionarios');
            $table->foreign('coordenador_id')->references('id')->on('funcionarios');
            $table->foreign('gerente_id')->references('id')->on('funcionarios');
            $table->foreign('diretor_id')->references('id')->on('funcionarios');
            $table->foreign('sexo_id')->references('id')->on('sexos');
            $table->foreign('setor_id')->references('id')->on('setores');
            $table->foreign('cargo_id')->references('id')->on('cargos');
            $table->foreign('turno_id')->references('id')->on('turnos');

        });

The execution order of the migration files needs to be checked first. the referenced table migration should be done before refer it in integrity constains.

All of your foreign keys must be unsigned 

    $table->integer('supervisor_id')->unsigned()->nullable();
    $table->integer('coordenador_id')->unsigned()->nullable();
    $table->integer('gerente_id')->unsigned()->nullable();
    $table->integer('diretor_id')->unsigned()->nullable();
    $table->integer('sexo_id')->unsigned()->nullable();
    $table->integer('setor_id')->unsigned()->nullable();
    $table->integer('cargo_id')->unsigned();
    $table->integer('turno_id')->unsigned()->nullable();

You get error code 1005 when there is a wrong primary key reference in your code. Here is what you can do to debug your code:

  1. Make sure that your FK you are referring actually exists.
  2. Make sure that you don't have typo. The case must be same too.
  3. FK-linked fields must match definitions exactly.

Without seeing your table structure, from your below query it could be that

both column id and supervisor_id doesn't match datatype and size. Make sure both datatype and size are same for both this column

Also, check if any other constraint with name funcionarios_supervisor_id_foreign already exists. If so, try providing a different name for the constraint.

alter table `funcionarios` add constraint funcionarios_supervisor_id_foreign 
foreign key (`supervisor_id`) references `funcionarios` (`id`)
