无服务器 slsw.lib.entries 始终为空

Question

我正在尝试使用无服务器部署到 Lambda。在我的 webpack.config.js 中，我有以下条目：

const slsw = require('serverless-webpack')
module.exports = {
  entry: slsw.lib.entries,
  ...
}

在我的 serverless.yml 中，我声明函数如下：

functions:
  importUsersFromS3:
    handler: handlers.handler

和 handlers.js 看起来像这样：

exports.handler = async function (event, context) {
  awaitcaptureAsyncFunc('handleSplitSpreadsheet', () => {
    context.callbackWaitsForEmptyEventLoop = false
    log('event', { event })
    processLargeSpreadsheet(event, context)
  })
}

当我运行 serverless webpack --out dist --stage dev --region us-east-1 我得到以下错误：

所以我的文件夹结构是这样的

app
├── lambda
|   ├── usersApi
|   |   ├── handlers.js
|   |   ├── serverless.yml
|   |   └── package.json
|   ├── severalServiceFolders
|   └── webpack.config.js
└── package.json

在 app/lambda/usersApi/package.json 我有这些 devDependencies:

"serverless-plugin-aws-alerts": "1.2.4",
"serverless-plugin-tracing": "^2.0.0",
"serverless-webpack": "^5.3.1"

原来删除它们使错误消失了。

仅在根 package.json 中引用 serverless 是 "serverless-webpack": "^5.3.1"

无服务器 slsw.lib.entries 始终为空

serverless slsw.lib.entries is always empty

javascript

webpack

serverless
