Erro de migração no laravel

Pessoal, estou com um problema para criar uma foreign com as migrations do laravel.

 SQLSTATE[HY000]: General error: 1215 Cannot add foreign key constraint (SQL: alter table `users` add constraint `users_equipe_id_foreign` foreign key (`equipe_id`) references `equipe` (`id`))

 at /home/vagrant/code/vendor/laravel/framework/src/Illuminate/Database/Connection.php:664
 660| // If an exception occurs when attempting to run a query, we'll format the error
 661| // message to include the bindings with SQL, which will make this exception a
 662| // lot more helpful to the developer instead of just the database's errors.
 663| catch (Exception $e) {
 > 664| throw new QueryException(
 665| $query, $this->prepareBindings($bindings), $e
 666| );
 667| }

 Exception trace:

 1 PDOException::("SQLSTATE[HY000]: General error: 1215 Cannot add foreign key constraint")

	Create Users seed

public function up()
 {
 Schema::dropIfExists('users');
 Schema::enableForeignKeyConstraints();
 Schema::create('users', function (Blueprint $table) {

 $table->bigIncrements('id')->index();

 //Informações do atleta
 $table->string('name');
 $table->string('tel')->nullable();
 $table->string('nacionalidade',2)->nullable();
 $table->string('cpf', 11)->unique();
 $table->date('data_nascimento')->nullable();
 $table->char('genero', 1);

 //Informações de login
 $table->string('email')->unique();
 $table->string('avatar')->nullable()->default('user_defatult.png');
 $table->string('password');
 $table->string('status')->nullable()->default(1);
 $table->string('permission')->nullable()->default('app.atleta');
 $table->timestamp('email_verified_at')->nullable();
 $table->rememberToken();

 //Demais informações
 $table->string('cep')->nullable();
 $table->string('logradouro')->nullable();
 $table->string('bairro')->nullable();
 $table->string('cidade')->nullable();
 $table->string('uf')->nullable();
 $table->string('complemento')->nullable();
 $table->string('emer_nome')->nullable();
 $table->string('emer_tel')->nullable();
 $table->integer('equipe_id')->unsigned();

 $table->timestamps();

 });
 }

	Create Tables Equipe:

 public function up()
 {
 Schema::dropIfExists('equipes');
 Schema::create('equipes', function (Blueprint $table) {
 $table->bigIncrements('id')->index();
 $table->string('nome');
 $table->integer('status');
 $table->timestamps();
 });
 }

	Alter Table Users

 public function up()
 {
 Schema::table('users', function (Blueprint $table) {
 $table->foreign('equipe_id')->references('id')->on('equipe');
 });
 }

	 

	a migration é executada nesta ordem, mas o errro persiste
