Error: Cannot find module 'node-fetch'\nRequire stack:\n- /var/task IN AWS Lambda

Question

我在本地使用 node-fetch 时没有收到任何错误 package.json 也有 node-fetch 依赖项，但是当我在 aws lambda 中部署时，找不到此依赖项。从 'node-fetch';

导入提取

{
  "errorType": "Runtime.ImportModuleError",
  "errorMessage": "Error: Cannot find module 'node-fetch'\nRequire stack:\n- /var/task/query1.js\n- /var/task/query1Main.js\n- /var/runtime/UserFunction.js\n- /var/runtime/index.js",

您必须将外部包声明为 lambda 的层 https://docs.aws.amazon.com/lambda/latest/dg/configuration-layers.html

Error: Cannot find module 'node-fetch'\nRequire stack:\n- /var/task IN AWS Lambda

Error: Cannot find module 'node-fetch'\nRequire stack:\n- /var/task IN AWS Lambda

node.js

aws-lambda

aws-appsync
