我有一个store.js文件内容为：
import { writable } from 'svelte/store';
export const generateds = writable(0);
console.log("generateds", $generateds)
每次我尝试访问 $ generateds （在此文件内部或外部）时，我都会收到此错误：
Uncaught ReferenceError: $generateds is not defined
at stores.js:4
at main.js:6
当我在新项目中使用store时，没有问题。我找不到我当前项目的问题所在。
这是我正在使用的 npm 包的列表：

引用存储值的 $ 语法只能在 Svelte 组件内部使用。从the docs https://svelte.dev/docs#4_Prefix_stores_with_%24_to_access_their_values（强调我的）：
每当您引用商店时，您都可以访问它的值组件内部通过在其前面添加 $ 字符来实现。这会导致 Svelte 声明前缀变量，并设置一个商店订阅，该订阅将在适当时取消订阅。
如果你需要获取普通JS文件中的值，你可以订阅它 https://svelte.dev/tutorial/writable-stores或使用 Svelte 的获取函数 https://svelte.dev/docs#get（订阅商店以获取值并立即取消订阅）。
import { generateds } from './store.js';
import { get } from 'svelte/store';
// method 1
const unsubscribe = generateds.subscribe((val) => { console.log(val); });
unsubscribe();
// method 2
console.log(get(generateds));
