return Redirect::route('users.show', $id);
}

用户模型如下

use Illuminate\Auth\Reminders\RemindableTrait;
use Illuminate\Auth\Reminders\RemindableInterface;
class User extends Eloquent implements UserInterface, RemindableInterface {
use UserTrait, RemindableTrait;
/**
* The database table used by the model.
*
* @var string
*/
protected $table = 'users';
/**
* The attributes excluded from the model's JSON form.
*
* @var array
*/
protected $hidden = array('password', 'remember_token');

I imagine you have a property in your User model like this:
我想你的 User 模型中有一个这样的属性：
<?php
class User extends Eloquent {
public $rules = array(
'email' => 'required|email|unique:users',
'password' => 'required|min:8',
);
}
This is a class instance property, but you're trying to access it statically (the error messages tells you such).
这是一个类实例属性，但您正在尝试静态访问它（错误消息告诉您这样）。
Simply add the statickeyword to the property:
只需将static关键字添加到属性中：
<?php
class User extends Eloquent {
public static $rules = array(
'email' => 'required|email|unique:users',
'password' => 'required|min:8',
);
}
