Firebase Cloud 功能：Typescript 无法编译为 JavaScript

Question

我计算机上的云功能可以使用 Javascript，但是当我使用 TypeScript 尝试它时，它不会编译为 Javascript。它不会创建 lib/index.js

当我运行 firebase deploy 时，它显示错误

Error: There was an error reading functions/package.json:

firebase deploy --debug 显示以下日志：

Having trouble? Try firebase [command] --help

我刚刚在另一个同事的 Macbook 上试过，在他的系统上完美运行，但在我的系统上不行。

请帮我解决这个问题。

Answer 1

我才知道没有安装 Typescript。

解决

sudo npm install -g typescript

现在可以正常使用了

Answer 2

如果您克隆包含节点项目（包括 Cloud Functions 项目）的存储库，您应该做的第一件事是更改到定义 package.json 的目录，然后运行 ​​npm install .这将重建未签入源代码控制的 node_modules 的内容。如果你不运行npm install，那么项目实际上不会知道任何关于 package.json 中定义的模块的任何信息。

Answer 3

我遇到了同样的问题： 打字稿只是不会编译。记录了很多错误，主要是这里的错误："error TS2300: Duplicate identifier 'AbortController'"

解决办法：

刚刚在 tsconfig.json 文件的“compilerOptions”属性中添加了以下行：

"typeRoots": ["node_modules/@types"] 

这样：

/functions/tsconfig.json

{ 
  {
    "compilerOptions": {
      "module": "commonjs",
      "noImplicitReturns": true,
      "noUnusedLocals": true,
      "outDir": "lib", 
      "sourceMap": true,
      "strict": true,
      "target": "es2017",
      "typeRoots": ["node_modules/@types"]  // <-- here
    },  
    "compileOnSave": true,
    "include": ["src"]
  }
}

之后编译就好了！

ps：不知道为什么如此自动创建所有内容的 firebase cli 会忘记我的项目设置中的这一特定代码行。如果有人知道，请分享。

Answer 4

这为我解决了问题

在尝试了许多解决方案以使构建工作后，当我取消注释 index.ts 中的代码时它工作了

import * as functions from "firebase-functions";

// // Start writing Firebase Functions
// // https://firebase.google.com/docs/functions/typescript
//
// export const helloWorld = functions.https.onRequest((request, response) => {
//   functions.logger.info("Hello logs!", {structuredData: true});
//   response.send("Hello from Firebase!");
// });

这是因为导入的functions变量声明了但没有使用
