由于神秘的语法错误，Firebase函数无法从visual studio部署(请参阅屏幕截图或屏幕录制)

Question

当我部署firebase函数时，由于语法问题，部署失败。请参阅屏幕截图中的终端窗口。错误主要包括"字符串必须是双引号"one_answers"预期缩进8个空格，但找到2个制表符"。在VisualStudioIDE中，我没有看到这些内联错误，所以我试图弄清楚当我试图将此函数部署到Firebase时为什么会出现这些错误。

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。

终端输出：

(base) samyoon@Sams-MBP FitnessApp % firebase deploy --only functions      
=== Deploying to 'fitnessapp-b3eea'...
i  deploying functions
Running command: npm --prefix "$RESOURCE_DIR" run lint

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,
})
});

我能够解决这个问题。我转到我的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"
]
}
}

并删除了这个部分：

"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功能：

firebase deploy --only functions

我的功能成功地部署到了Firebase，我可以在控制台中看到它。

尽管用例有所不同，但github的这篇文章有助于发现解决方案。
