我有一个Angular2项目,在Mac OS上创建并运行。但是当我在Windows上使用它时,它无法运行。 在Chrome中,我收到此错误:

答案 0 :(得分:23)
您是否在Example3
中使用class User
{
/* ... */
private $relation_type;
/**
* @var \AppBundle\Entity\Player
*
* @ORM\ManyToOne(targetEntity="AppBundle\Entity\Player")
* @ORM\JoinColumn(name="parent", referencedColumnName="id")
*/
private $parent;
}
class Player
{
}
class Example1 extends Player
{
}
0.7.3?若是,请改为0.7.2试试:
zone.js
运行package.json
尝试。
答案 1 :(得分:3)
目前最好的方法是将zone.js降级/升级到0.7.4
npm install --save zone.js@0.7.4
答案 2 :(得分:1)
0.8.x区现在已经出局,并且有更好的堆栈跟踪并且还修复了这个错误:
"zone.js": ">=0.8.12"
