启动Firestore /实时数据库的Firebase模拟器？

Question

我尝试通过个人项目和位于这里的firebase仿真套件Codelab启动Firebase防火墙和实时数据库模拟器：(https://firebase.google.com/codelabs/firebase-emulator#0)使用codelab，命令行在“firebase模拟器:start”之后打印以下内容

[....] codelab-initial-state % firebase emulators:start --import=./seed
i  emulators: Starting emulators: auth, functions, firestore, hosting
⚠  functions: The following emulators are not running, calls to these services from the Functions emulator will affect production: database, pubsub, storage
⚠  Your requested "node" version "10" doesn't match your global version "17". Using node@17 from host.
i  firestore: Importing data from /Users/lucasfrench/Documents/emulators-codelab/codelab-initial-state/seed/firestore_export/firestore_export.overall_export_metadata
i  firestore: downloading cloud-firestore-emulator-v1.13.1.jar...
Progress: =====================================================================================================================================================================> (100% of 61MB)
i  firestore: Firestore Emulator logging to firestore-debug.log
i  emulators: Shutting down emulators.
i  functions: Stopping Functions Emulator
i  firestore: Stopping Firestore Emulator
i  hub: Stopping emulator hub

Error: TIMEOUT: Port 8080 on localhost was not active within 60000ms

这是与我的个人项目使用实时数据库仿真器相同的错误。但是，对于其他产品(如auth模拟器)或访问UI仿真器，我没有任何问题。

这可能与本期有关。解决办法是指定本地主机地址(例如。127.0.0.1)，而不是localhost，并在firebase.json中添加一个主机属性，其中还有127.0.0.1。

"firestore": {
    "port": 8080,
    "host": "127.0.0.1"
},
