I was also getting the same error. What i was doing in users table is,

$table->unsignedInteger('role_id')->default(2); table->foreign('role_id')->references('id')->on('roles')->onDelete('cascade');

But i have created the role table after creating users table. So, i edited the role migration file name date before the users table filename date. Like this,

2013_01_22_091213_create_roles_table.php
