Firebase function 由于神秘的语法错误而无法从 Visual Studio 部署（请参阅屏幕截图或屏幕录像）

Question

当我部署我的 firebase function 时，由于似乎是语法问题，部署失败。 请参阅屏幕截图中的终端 window。 错误主要包括“字符串必须是双引号”和“预期缩进 8 个空格但找到 2 个制表符”。 在 VisualStudio IDE 中，我看不到这些错误，所以我试图弄清楚为什么当我尝试将此 function 部署到 Z035489FF8D092741943E4A8324 时会出现这些错误。

我在 Visual Studio 中使用 Typescript 并通过终端中的firebase deploy --only functions命令部署到 Firebase。

端子 Output：

(base) samyoon@Sams-MBP FitnessApp % firebase deploy --only functions      

=== Deploying to 'fitnessapp-b3eea'...

Error: functions predeploy error: Command terminated with non-zero exit code 1

代码：

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();
import {} from 'firebase-admin';

exports.createUser = functions.firestore

.document('users/{userId}')
.onCreate((snap, context) => {
  // Get an object representing the document
  // e.g. {'name': 'Marie', 'age': 66}
  const userData = snap.data();

  // access a particular field as you would any JS property
  const userUID = userData.uid;

  // perform desired operations ... create new WorkoutCycle document
  admin.collection("WorkoutCycles").doc().set({
    createdTimestamp: Date.now(),
    name: 'FunctionCreatedMe',
    user: 'users/'+userUID,
})
});

Answer 1

我能够解决这个问题。 我去了我的 firebase.json 文件，它看起来像这样：

    {
  "functions": {
    "predeploy": [
      "npm --prefix \"$RESOURCE_DIR\" run lint",
      "npm --prefix \"$RESOURCE_DIR\" run build"
    ]
  }
}

并删除了这部分：

"predeploy": [
  "npm --prefix \"$RESOURCE_DIR\" run lint",
  "npm --prefix \"$RESOURCE_DIR\" run build"
]

之后我使用以下命令部署了我的 function：

firebase deploy --only functions

我的 function 成功部署到 Firebase 并且我可以在控制台中看到它。

尽管用例不同，但这篇 github 帖子有助于发现解决方案。
