Schema::table('posts', function (Blueprint $table) {
    $table->unsignedBigInteger('user_id');

    $table->foreign('user_id')->references('id')->on('users');
});
OR

cannot add foreign key constraint laravel

Add it in two steps, and its good to make it unsigned too:
public function up()
{
    Schema::create('priorities', function($table) {
        $table->increments('id', true);
        $table->integer('user_id')->unsigned();
        $table->foreign('user_id')->references('id')->on('users');
        $table->string('priority_name');
        $table->smallInteger('rank');
        $table->text('class');
        $table->timestamps('timecreated');
    });
}

if still same error try removing unsigned() from the above code
