如何启动Firebase模拟器，我已经执行了here中提到的所有步骤。以下是我尝试运行模拟器时的输出：

✔  Firebase initialization complete!
users-iMac:~ users firebase emulators:start --only firestore
i  emulators: Starting emulators: firestore
⚠  emulators: It seems that you are running multiple instances of the emulator suite for project project_name. This may result in unexpected behavior.
✔  hub: emulator hub started at http://localhost:4400
⚠  firestore: Did not find a Cloud Firestore rules file specified in a firebase.json config file.
⚠  firestore: The emulator will default to allowing all reads and writes. Learn more about this option: https://firebase.google.com/docs/emulator-suite/install_and_configure#security_rules_configuration.
i  firestore: firestore emulator logging to firestore-debug.log

我遇到了同样的问题，中心似乎不能在低于8.4的firebase版本上工作，而您使用的是8.1.1。尝试升级到8.4.3。
