Runtime.ImportModuleError:错误:找不到模块'onCreateRadonData‘
Runtime.ImportModuleError:错误:找不到模块'onCreateRadonData‘
提问于 2021-08-01 12:28:54
我正在尝试使用AppSync和Serverless将DynamoDB流部署为lambda函数。部署进行得很顺利，没有任何错误。但是当我触发lambda在我的DynamoDB表中创建一个新实例时，它失败了，抛出了这个错误：
{
"errorType": "Runtime.ImportModuleError",
"errorMessage": "Error: Cannot find module 'onCreateRadonData'\nRequire stack:\n- /var/runtime/UserFunction.js\n- /var/runtime/index.js",
"stack": [
"Runtime.ImportModuleError: Error: Cannot find module 'onCreateRadonData'",
"Require stack:",
"- /var/runtime/UserFunction.js",
"- /var/runtime/index.js",
" at _loadUserApp (/var/runtime/UserFunction.js:100:13)",
" at Object.module.exports.load (/var/runtime/UserFunction.js:140:17)",
" at Object.<anonymous> (/var/runtime/index.js:43:30)",
" at Module._compile (internal/modules/cjs/loader.js:999:30)",
" at Object.Module._extensions..js (internal/modules/cjs/loader.js:1027:10)",
" at Module.load (internal/modules/cjs/loader.js:863:32)",
" at Function.Module._load (internal/modules/cjs/loader.js:708:14)",
" at Function.executeUserEntryPoint [as runMain] (internal/modules/run_main.js:60:12)",
" at internal/main/run_main_module.js:17:47"
]
}这很奇怪，因为我通常在以一种不好的方式导入一些模块/依赖项时会发生这种情况。但是在错误onCreateRadonData中提到的函数是lambda本身的名称，并且在部署过程中，可以清楚地看到该函数部署得很好，所以我不知道发生了什么……

export const handler = (event) => {
console.log('Hello from lambda')
return;
}注意:我也尝试过exports.handler = (event) ...方法，但我抛出了相同的错误。
代码结构如下：
- src/handlers/onCreateRadonData.ts
- mapping-templates/files with mapping templates.vtl
- serverless.yml
- package.json如您所见，我在src的handlers文件夹中只有一个名为onCreateRadonData.ts的文件。这就是全部，其余的文件都在根目录中。
你知道我做错了什么吗？谢谢大家！

好了，伙计们，我知道了。因为我使用的是typescript，所以我必须导入serverless-typescript插件来将所有的ts文件转换为js。
