无服务器部署因使用需求AND导入而失败

[英]Serverless Deployment failing due to usage of require AND import

I know it is a bad practice to use the import as well as require statements in the same file, but I heard it shouldn't cause any problems. 我知道在同一文件中使用import以及require语句是一种不好的做法，但是我听说它不会造成任何问题。
Why will my lambda fail then (when running yarn run local ) and complain about an 'Unexpected Identifier' when encountering the import statement? 为什么我的lambda会失败（当yarn run local运行yarn run local时），在遇到import语句时抱怨“意外标识符”？
Here's the current codebase . 这是当前的代码库。 The problem lies in the functions/edge.js file. 问题出在functions / edge.js文件中。

EDIT: I'm sorry I haven't clearly formulated my question. 编辑：对不起，我还没有明确提出我的问题。 Replacing the import statement with the seemingly equivalent const middleware = require('@sapper/server'); 用看似等效的const middleware = require('@sapper/server'); import const middleware = require('@sapper/server');代替import语句const middleware = require('@sapper/server'); results in an error: It can't find the module - with import it works perfectly fine, even during production. 导致错误：找不到模块-导入后，即使在生产过程中，它也可以正常工作。

Because AWS Lambdas run on node, and the version of node AWS Lambda use don't support import keyword. 由于AWS Lambda在节点上运行，并且AWS Lambda使用的节点版本不支持import关键字。

EDIT: As @Michael states in the comments, you need to install the proper packages. 编辑：如@Michael在评论中指出，您需要安装适当的软件包。 Either by using npm or looking where the package should be (I guess you should follow sapper.svelte instructions properly). 通过使用npm或查看软件包的位置（我猜您应该正确遵循sapper.svelte指示）。 import would fail the same way as require as the package don't exists. import将以与require相同的方式失败，因为该软件包不存在。 Is not an "import vs require" problem, but a non-existent package problem. 这不是一个“导入与需求”问题，而是一个不存在的软件包问题。
