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');

});

Answer

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();
