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

Question

我在 VS Code 和 Node 8.9.3 中本地运行 azure 工具，并使用“func new”创建的 Typescript 2.6.2 Azure 函数。我不得不将"scriptFile": "index.ts", 添加到function.json 中才能做到这一点——否则它会抱怨找不到主脚本。但是现在它似乎在所有注册中都成功了——在不存在的路由上适当地 404ing，但是当我使用 Postman 发布到它或从浏览器 GET 时它会发出这个：

Typescript 在本地也能很好地处理其他事情。其他人遇到这个错误吗？我该如何解决？

我认为 Azure Functions 无法识别 Typescript 文件。在运行之前，您可能需要通过tsc 命令将您的 ts 代码编译成 javascript。

你也可以按照这个文档来编译和运行它： https://github.com/TsuyoshiUshio/TypeScriptCosmosSpike#compile-typescript
