具体错误信息如下：
上面的空是打印的，cc.renderer._forward，， 这个值在后面加载其他的 材质的时候， 表现正常， 为一个非空值。。请教下官方 是否有可能是因为 加载 load quick_compile_project 这个脚本导致出现的问题 , @Knox
补充一下， 这边找到出错的代码在 cc.EffectAsset 的 onLoad 函数中， 在这里面打印信息， Asset 的名称是 builtin-2d-sprite, 是这个材质出错了么？ 求助官方
能看到完整的调用栈么

顺序不太对啊
这个应该在报错之前才对
但是我这边运行确实是在报错之后的， 我在浏览器上面运行，没有报错， load quickcompile_project 确实是在cc.EffectAsset 加载之前运行的， 但是在模拟器上或者是在 手机上， 就不对了。 另外新建了一个项目， 在模拟器上运行，没有报错， 现在这边在测试，新建很多脚本， 延长 load quickcompile_project 的运行时间， 看是否能在空项目上 重现 cc.EffectAsset 加载 运行在 load quickcompile_project 之前
延长 load quickcompile_project 的运行时间， 看是否能在空项目上 重现 cc.EffectAsset 加载 运行在 load quickcompile_project 之前
应该跟脚本数量没关系的，代码里面是加载脚本完成后才进行加载effect资源
得想办法看下错误的effect加载是在什么时候触发的。要在_initEngine之后执行才正常
_initEngine里面会去初始化_forward
我这边再找下 看看怎么触发加载 Effect 的
非常感谢， 找到问题了， 自己代码里面写的问题， 在代码的最外围调用了手动加载资源，导致出现问题，这个应该也属于一个bug吧， 具体代码如下:
`import { BlockInfo } from “…/…/…/Configs/StageConfig”;
const { ccclass, requireComponent } = cc._decorator;
@ccclass
@requireComponent(cc.Sprite)
@requireComponent(cc.RigidBody)
export default class BaseBlock extends cc.Component {
protected static prefab: cc.Prefab = null;
static init() {
cc.loader.loadRes("Prefabs/" + cc.js.getClassName(this), cc.Prefab, (error: Error, prefab: cc.Prefab) => {
this.prefab = prefab;
});
}
}
BaseBlock.init();
`
加载资源不要写在代码最外面，否则会在引擎初始化之前就去加载，导致出现问题。你可以写在onLoad或者start都可以，得保证在引擎初始化之后再加载资源
