Firebase Cloud 函數：Typescript 無法編譯為 JavaScript

Question

我計算機上的 Cloud 函數可以使用 Javascript，但是當我嘗試使用 TypeScript 時，它無法編譯為 Javascript。 它不會創建 lib/index.js

當我運行 firebase deploy 時，它顯示的錯誤是

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

firebase deploy --debug 顯示以下日志：

Having trouble? Try firebase [command] --help

我剛剛在另一位同事的 Macbook 上嘗試過，它在他的系統上完美運行，但在我的系統上卻沒有。

請幫我解決這個問題。

Answer 1

我遇到了同樣的問題：Typescript 無法編譯。 記錄了很多錯誤，主要是這里的錯誤： “錯誤 TS2300: Duplicate identifier 'AbortController'”

解決方案：

剛剛在 tsconfig.json 文件的“compilerOptions”屬性中添加了以下行：

"typeRoots": ["node_modules/@types"]

像那樣：

/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"]
  }
}

之后它編譯就好了！

ps：不知道如何或為什么如此自動創建所有內容的 firebase cli 會在我的項目設置中忘記這行特定的代碼。 如果有人知道，請分享。

Answer 2

如果您克隆包含節點項目（包括 Cloud Functions 項目）的存儲庫，您應該做的第一件事是切換到 package.json 定義的目錄，然后運行npm install 。 這將重建未簽入源代碼管理的 node_modules 的內容。 如果您不運行npm install ，那么該項目實際上將不知道有關 package.json 中定義的任何模塊的任何信息。

Answer 3

我開始知道未安裝 Typescript。

解決了

sudo npm install -g typescript

現在它正在工作 ifne

Answer 4

這為我解決了

在嘗試了許多解決方案以使構建正常工作后，當我取消對index.ts的代碼進行注釋時它起作用了

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!");
// });

這是因為導入的functions變量已聲明但未使用
