svelte 包中缺少生命周期说明符。苗条套件

Question

我目前正在使用 svelte 的上下文 api 在我的应用程序中传递用户数据。突然我遇到了这个错误，在我能找到的任何地方几乎没有任何文档。错误信息如下。Missing "./types/runtime/internal/lifecycle" specifier in "svelte" package。从我还将发布的完整控制台输出来看，它来自这里的这个文件：

<script lang="ts">
    import { getContext } from 'svelte';
    import HtmlGenerator from './generate_html';
    import type { Field } from './generate_html';
    import { setContext } from 'svelte/types/runtime/internal/lifecycle';
    import { UserContext } from '../../context';

    setContext('UserContext', UserContext);

    const { is_logged_in, user } = getContext('UserContext');
</script>

为了简单起见，我省略了不相关的代码。直到我尝试使用 context Api 时才开始收到此错误。这是完整的控制台输出：

这段代码甚至可以在另一个项目中使用，我已经检查过我的配置文件都很好，而且看起来都很好。也许这个项目已损坏？

我尝试查看配置文件：一切似乎都很好。尝试关闭文件的打字稿：仍然没有。重新启动开发服务器：同样的问题。

正确的导入路径setContext是'svelte'：

import { setContext } from 'svelte';

VSCode 中的自动完成功能有时会出于某种原因从这些内部路径自动导入，这就是您可能最终得到该导入行的原因。
