Firebase-tools: No se puede establecer la configuración de propiedad de #<object>que solo tiene un getter</object>

@ boddy33 eh ok, eso es extremadamente extraño. ¿No hay absolutamente nada más firebase-debug.log ? ¿O si ejecuta el comando con --debug ?

Parece que es un error en el tiempo de ejecución del emulador.

Parece que esto es un problema con v8.xx La degradación a v7.16.2 funciona.

Tengo la sensación de que esto puede estar relacionado con la versión de firebase-functions de hoy:
https://github.com/firebase/firebase-functions/releases/tag/v3.6.2

Debería ser algo muy reciente. En cuanto a otros problemas, el emulador v8.xx estaba funcionando en algún momento (y la v8.4.0 se lanzó hace una semana).

Hola,
tengo el mismo problema :)

gracias @ uditha-atukorala funciona :)

cuando instale el paquete [email protected] entonces
Las solicitudes HTTP funcionan para mí

La solución viene en # 2302 ... si se aprueba y se fusiona, intentaremos lanzarlo lo antes posible

Me encontré exactamente con el mismo problema. Mac OS

esto me ha dejado perplejo durante las últimas horas. Tengo el mismo index.js que @ boddy33 e incluso sucede cuando index.js está vacío. Aquí está mi firebase-debug.log:

gracias por eso ... justo a tiempo

validado. Gracias.

Hola
Hace aproximadamente 2 días estaba implementando funciones y todo salió sin problemas, desafortunadamente desde ayer no puedo implementar. Tenía paquetes bastante viejos:

    "firebase": "^5.9.2",
    "firebase-admin": "~8.9.0",
    "firebase-functions": "^3.3.0",
    "firebase-tools": "^4.0.0",

y estaba obteniendo lo siguiente:

pero pudo ejecutar funciones localmente (--serve).

Hoy he actualizado todas las dependencias a versiones más nuevas, que en teoría deberían incluir una revisión, pero desafortunadamente ahora tengo un nuevo error, el mismo que en este número.

    "firebase": "^7.14.5",
    "firebase-admin": "~8.10.0",
    "firebase-functions": "^3.6.2",
    "firebase-tools": "^8.4.1",

No puedo implementar funciones, pero ni siquiera puedo ejecutarlas localmente debido al mismo problema.

La solución se acaba de lanzar en la versión 8.4.1 de firebase-tools

¿Deberían mis funciones desplegarse correctamente si tengo las últimas versiones?

@samtstern ^
No estoy seguro de si este problema debería resolverse.

@jakubjodelka, ¿puedes intentar borrar tu carpeta node_modules y ejecutar npm install nuevo? Si esto sigue sucediendo después de eso y con firebase --version mostrando 8.4.1 hágamelo saber.

Gracias. Trabajando para mí ahora.

Todavía lo entiendo

@COFFEEEADDICT verifique que firebase --version muestre 8.4.1

Hola chicos,

Recibí este error después de una actualización en el paquete firebase-functions (3.6.2).

En mi caso, la solución fue eliminar /node_modules y degradar el firebase-functions a la versión anterior ( npm install --save [email protected] ).

Hola chicos,

La primera vez que verifiqué qué versión instaló la mía fue 8.1.1
Actualice firebase-tools llamando

sudo npm i -g firebase-tools

Esto instalará la última versión 8.4.1
Y solucionó mi problema.
De hecho, he instalado la última función de base de fuego y administrador
"firebase-admin": "8.12.1",
"firebase-functions": "3.6.1",

Espero que hayas solucionado el problema.

trabajando gracias @iamsrujal

⚠ TypeError: no se puede establecer la configuración de propiedad de #

Tengo este mismo problema y no desaparece incluso después de actualizar firebase-tools. Cuando intento ejecutar el emulador, falla. En firebase-debug.log muestra:

¿Cómo puedo arreglarlo? Totalmente atrapado aquí ...

Para aquellos que aún experimentan este problema: si pueden reproducir este problema en un proyecto recién inicializado de una manera que podamos copiar, presente un nuevo problema y lo intentaremos.

En caso de que ayude a alguien: tuve que usar la versión explícita para actualizar las herramientas y luego el problema desapareció:
sudo npm i -g [email protected]

Sistema
Mac OS Catalina: 10.15.4
Nodo: v10.21.0
Java: versión de openjdk "14.0.1" 2020-04-14

Actualice al 07/09/2020 que este problema aún existe al usar "firebase-admin": "^8.10.0", .
Tuve que actualizar a "firebase-admin": "^8.12.1", y verificar que tengo "firebase-tools": "8.4.1"

Misma configuración que JohnGeorgiadis. El mismo problema...

Jugué con diferentes versiones de varias dependencias sin resolver.

Quizás esto sea útil para alguien: Mi linux estaba usando "/usr/local/lib/node_modules/firebase-tools/lib/bin/firebase.js" cada vez que escribía "firebase" en la consola, por lo que estaba usando el 7.12. 0 versión del paquete. Cambié el enlace simbólico y ahora estoy seguro de que estoy usando la versión 8.6.0.

8.6.0

La palabra _local_ es la clave

Una instalación global instalará firebase-tools en '/ usr / local / lib / node_modules'. Sin embargo, el problema resaltado por OP apunta a una ruta diferente: '/ usr / lib / node_modules / firebase-tools /'.
En la primera ruta tenía la última versión de firebase-tools 8.6.0, pero la versión 7.0.2 en la segunda ruta.

Una base de fuego -V devolvió 7.0.2

Aquí hay un comentario relevante (de una discusión aquí: https://stackoverflow.com/q/5926672/7461599)

installing without -g option will install a module to you working directory e.g. if you make a directory say ~/Desktop/tmp then cd ~/Desktop/tmp then do npm install appium then do ls you will see node_modules package-lock.json because you have installed a node module appium to your working directory... super confusing because -g should essentially be the default but is not.

Lo que hizo por mí fue npm uninstall firebase-tools , luego asegurándome de tener instalada la última versión con -g . Ahora, firebase -V apunta a la ruta correcta con la versión actualizada, y el emulador de base de fuego se ejecuta sin problemas.

En caso de que ayude, tuve un conflicto entre mi npm global [email protected] y mi hilo global [email protected] . Eliminar mi versión global de npm solucionó mi problema de devolver 7.0.0 de firebase -V

estaba obteniendo el error anterior debido a la versión de nodo diferente utilizada durante

1. inicialización del proyecto (firebase init) => versión del nodo => v8.xx
2. proyecto en ejecución (emuladores de base de fuego: inicio) => versión del nodo => v12.xx

Resolví el problema haciendo la misma versión de nodo

No puedes (fácilmente). Intentaría encontrar un binario similar y colocarlo en el mismo camino
