我有这样的功能:
exports.deleteUser = functions.https.onCall(async(data, context) => {
let id = context.auth.uid;
console.log('Delete user: ' + id);
//delete from algolia
usersIndex.deleteObject(id);
console.log(id + 'Deleted from algolia');
//delete user following
await admin.firestore().collection('users').doc(id).collection('Following').get()
.then(async(snapshot) => {
for await (const document of snapshot.docs) {
await admin.firestore().collection('users').doc(document.documentId)
.update({
'NumberOfFollowers': FieldValue.increment(-1)
});
await admin.firestore().collection('users').doc(document.documentId).collection('Followers')
.doc(id).delete();
}
return console.log('Following of ' + id + ' deleted');
});
...
但是当我尝试将它部署到 firebase 函数时,我收到了以下错误:
! functions[deleteUser(us-central1)]: Deployment error.
Function failed on loading user code. Error message: Code in file index.js can't be loaded.
Is there a syntax error in your code?

找到这个:https://github.com/nodejs/node/issues/21617但我确实将我的 ForLoop 设置为异步函数...
最佳答案
for-await loops are first available in node in version 10 .您可能在本地或 package.json 中使用较早的 Node 版本。
您需要确保在用于部署的两个本地 Node 中至少使用 Node 10:
$ node --version
...should print 10.x.x or later
并且还可以在 package.json 中定位 Node 10,以便可以告诉 Cloud Functions 使用哪个版本进行部署:
"engines": {
"node": "10"
}
