Question

问题：

\n

我正在尝试构建将部署到 AWS Lambda 的 Typescript 代码。然而，在 Aws Sam 构建时，我遇到了标题中提到的错误。以下是确切的错误。

\n

于是我搜索了一下，发现我的node_modules没有aws-sdk，所以我安装它

\n

npm install aws-sdk\n

\n

即使我安装了

\n

npm install --save-dev @types/node\n

\n

但不知何故 esbuild 失败了，错误提到将路径标记为外部，有人可以指导如何将其标记为外部吗？我正在分享我的 tsconfig.json 如下

\n

{\n    "compilerOptions": {\n      "target": "es2020",\n      "strict": true,\n      "preserveConstEnums": true,\n      "noEmit": true,\n      "sourceMap": false,\n      "module":"es2015",\n      "moduleResolution":"node",\n      "esModuleInterop": true, \n      "skipLibCheck": true,\n      "forceConsistentCasingInFileNames": true,  \n    },\n    "exclude": ["node_modules", "**/*.test.ts"]\n  }\n

将属性添加External:到“template.yaml”中的 Metadata.BuildProperties

前任。）

Metadata: # Manage esbuild properties
  BuildMethod: esbuild
  BuildProperties:
    Minify: true
    Target: "es2020"
    Sourcemap: true
    EntryPoints: 
      - app.ts
    # ==== add below ====
    External:
      - "@aws-sdk/lib-dynamodb"
      - "@aws-sdk/client-dynamodb"
