Issue

 

% firebase emulators:start
i  emulators: Starting emulators: functions, firestore
⚠  emulators: It seems that you are running multiple instances of the emulator suite for project ihp-test-6198e. This may result in unexpected behavior.
⚠  functions: The following emulators are not running, calls to these services from the Functions emulator will affect production: auth, database, hosting, pubsub, storage
✔  functions: Using node@16 from host.
i  emulators: Shutting down emulators.
i  functions: Stopping Functions Emulator
i  hub: Stopping emulator hub
⚠  firestore: Port 8080 is not open on localhost, could not start Firestore Emulator.
⚠  firestore: To select a different host/port, specify that host/port in a firebase.json config file:
      {
        // ...
        "emulators": {
          "firestore": {
            "host": "HOST",
            "port": "PORT"
          }
        }
      }
i  emulators: Shutting down emulators.

Error: Could not start Firestore Emulator, port taken.

종료되지 않은 에뮬레이터가 있기 때문에 에뮬레이터를 시작했을때 문제가 되는 것이다. 그래서 기존에 띄운 에뮬레이터를 종료시키고 다시 재기동 시키면 된다.

 

 

solution

lsof -ti tcp:8080 | xargs kill
