當需要外部模塊時，不會部署使用無服務器的 AWS Lambda 函數

Question

我目前正在嘗試使用無服務器部署 AWS lambda 函數。 如果我不包含任何外部模塊，我可以獲得正確部署並響應的功能，但是一旦我嘗試包含 dynogels 和 Joi：

const dynogels = require("dynogels");
const Joi = require("@hapi/joi");

serverless deploy命令不會通過“打包外部模塊”

不包括外部模塊時的完整輸出：

❯ sls deploy
{ addHandler: './addHandler.js' }

包含外部模塊時的完整輸出：

❯ sls deploy

Serverless: Bundling with Webpack...
   3 modules
Serverless: Package lock found - Using locked versions
Serverless: Packing external modules: dynogels@^9.1.0, @hapi/joi@^17.1.0

軟件包已安裝。 我不明白為什么這沒有部署。 有什么辦法可以從部署中看到一些錯誤？ --verbose似乎沒有提供太多額外的信息。 謝謝你的幫助！

嘗試將Lambda 層用於您的 SAM 應用程序。
