我的也是啊

想問有查到什么原因嗎？我的也是

import?{observable,?isArrayLike,?computed}?from?'mobx';

//observable.box
/*
const?arr?=?observable(['a','b','c']);
console.log(arr[0],Array.isArray(arr),isArrayLike(arr));

*/


/*const?map?=?observable(new?Map())
map.set('a',1)
console.log(map.has('a'));

map.delete('a');
console.log(map.has('a'));*/

/*var?num?=?observable.box(20);
var?str?=?observable.box('hello');

num.set(50);
str.set("world");

console.log(num.get(),?str.get());*/


class?Store?{
????@observable?array?=?[];
????@observable?obj?=?{};
????@observable?map?=?new?Map();

????@observable?str?=?'hello';
????@observable?num?=?20;
????@observable?bool?=?false;

????
}

//computed


var?store?=?new?Store();

var?foo?=?computed(function?()?{
????return?store.str?+?'/'?+?store.num;
})

foo.observe(function?(change)?{
????console.log(change)
})
store.str?=?'world';
store.num?=?3333333;
console.log(foo.get());

我的是可以出發的，你的環境配置正確么
