node.js - 任何人都可以引导我朝着正确的方向前进，让这个 Azure 函数在它输出“无法找到模块'@azure/functions'的地方？

问题描述

我正在尝试使用 TypeScript 在本地运行 Azure 函数。我在 TypeScript 方面有相当多的经验，而且通常在 JS 世界中，但在这些消费型云服务方面却没有那么多经验。我正在运行最新版本的核心工具，所以运行func -v返回3.0.3160 我尝试重新安装工具。同样的问题在多台机器和操作系统中仍然存在。

函数.ts

const httpTrigger: AzureFunction = async function (context: Context, req: HttpRequest): Promise<void> {
    context.log('HTTP trigger function processed a request.');
    
    // Contents of foo are irrelevant
    foo(context, req);
    context.res = {
        status: 200,
    };
};
export default httpTrigger;

错误

在本地运行 azure 函数时，我运行“yarn run build:start”，并从脚本元素执行 yarn clean、yarn build 和 yarn run start。这是终端输出到控制台的内容。
