Azure函数本地“系统找不到指定的文件”在TypeScriptCompiler.CompileAsync（）期间

Question

我在VS Code和Node 8.9.3中本地运行azure工具，并使用“func new”创建了Typescript 2.6.2 Azure Function。我不得不将"scriptFile": "index.ts",添加到function.json甚至到目前为止 - 否则它抱怨它无法找到主脚本。但现在它似乎在所有注册中都取得了成功 - 在不存在的路由上适当地进行了404，但是当我使用Postman或GET从浏览器发送到它时它会发出这种情况：

Typescript在其他方面适用于本地。其他人遇到此错误？我该如何解决？

我不认为Azure Functions可以识别Typescript文件。在运行之前，您可能需要通过tsc命令将ts代码编译为javascript。

您可以按照此文档编译并运行它：https://github.com/TsuyoshiUshio/TypeScriptCosmosSpike#compile-typescript
