Firebase-tools: Não é possível definir a configuração da propriedade de #<object>que tem apenas um getter</object>

@ boddy33 huh ok isso é extremamente estranho. Não há absolutamente nada mais firebase-debug.log ? Ou se você executar o comando com --debug ?

Parece que é um bug no tempo de execução do emulador.

Parece que este é um problema com a v8.xx O downgrade para a v7.16.2 funciona.

Tenho a sensação de que isso pode estar relacionado ao lançamento de funções do firebase de hoje:
https://github.com/firebase/firebase-functions/releases/tag/v3.6.2

Devo ser algo muito recente. Olhando para outros problemas, o emulador v8.xx estava funcionando em algum ponto (e a v8.4.0 foi lançada há uma semana).

Oi,
tem o mesmo problema :)

obrigado @ uditha-atukorala, funciona :)

ao instalar o pacote [email protected] então
Solicitações HTTP funcionam para mim

A correção está chegando em # 2302 ... se for aprovado e mesclado, tentaremos lançar o mais rápido possível

Encontrando exatamente o mesmo problema. Mac OS

isso me deixou perplexo nas últimas horas. Eu tenho o mesmo index.js que @ boddy33 e isso acontece até mesmo quando index.js está vazio. Aqui está meu firebase-debug.log:

estamos esperando curiosos pela aprovação

A correção acaba de ser lançada na versão 8.4.1 de firebase-tools

obrigado por isso ... bem na hora

validado. Obrigado.

Olá
Faz uns 2 dias estava fazendo o deploy de funções e correu tudo sem problemas, infelizmente desde ontem não estou conseguindo fazer o deploy. Eu tinha pacotes bastante antigos:

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

e eu estava recebendo o seguinte:

mas foi capaz de executar funções localmente (--serve).

Hoje eu atualizei todas as dependências para versões mais recentes, que em teoria deveriam incluir um hotfix, mas infelizmente agora estou recebendo um novo bug, o mesmo que neste problema.

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

Não consigo implantar funções, mas não consigo nem executá-las localmente por causa do mesmo problema.

A correção acaba de ser lançada na versão 8.4.1 de firebase-tools

Minhas funções devem ser implantadas corretamente se eu tiver as versões mais recentes?

@samtstern ^
Não tenho certeza se este problema deve ser resolvido.

@jakubjodelka você pode tentar limpar sua pasta node_modules e executar npm install novamente? Se isso continuar acontecendo para você depois disso e com firebase --version mostrando 8.4.1 me avise.

Obrigado. Trabalhando para mim agora.

Eu ainda estou entendendo Eu fiz tudo acima, alguma ideia?

@COFFEEEADDICT verifique se firebase --version mostra 8.4.1

Oi pessoal,

Recebi este erro após uma atualização no pacote firebase-functions (3.6.2).

No meu caso, a solução foi excluir /node_modules e fazer o downgrade de firebase-functions para a versão anterior ( npm install --save [email protected] ).

Ola pessoal,

A primeira verificação de qual versão você instalou a minha foi 8.1.1
Atualize firebase-tools chamando

sudo npm i -g firebase-tools

Isso instalará a versão mais recente 8.4.1
E isso resolveu meu problema.
Na verdade, eu instalei a função mais recente do firebase e admin
"firebase-admin": "8.12.1",
"firebase-functions": "3.6.1",

Espero que você tenha corrigido o problema.

trabalhando, obrigado @iamsrujal

Ainda estou recebendo ajuda para o problema?

Estou tendo o mesmo problema e ele não desaparece mesmo depois de atualizar o firebase-tools. Quando tento executar o emulador, ele falha. No firebase-debug.log, ele mostra:

Como posso corrigir isso? Totalmente preso aqui ...

Para aqueles que ainda estão tendo esse problema: se você pode reproduzir esse problema em um projeto recém-inicializado de forma que possamos copiar, registre um novo problema e nós tentaremos.

Caso ajude alguém: tive que usar a versão explícita para atualizar as ferramentas e aí o problema foi embora:
sudo npm i -g [email protected]

Sistema
Mac OS Catalina: 10.15.4
Nó: v10.21.0
Java: versão openjdk "14.0.1" 2020-04-14

Atualize a partir de 09/07/2020, este problema ainda existe ao usar "firebase-admin": "^8.10.0", .
Tive que atualizar para "firebase-admin": "^8.12.1", e verificar novamente se tenho `" firebase-tools ":" 8.4.1 "

Mesma configuração que JohnGeorgiadis. Mesmo problema...

functions: Cannot set property config of #<Object> which has only a getter ⚠ Your function was killed because it raised an unhandled error.

Brincou com diferentes versões de várias dependências sem resolução.

Talvez isso seja útil para alguém: Meu linux estava usando "/usr/local/lib/node_modules/firebase-tools/lib/bin/firebase.js" sempre que eu digitava "firebase" no console, então estava usando o 7.12. Versão 0 do pacote. Mudei o link simbólico, e agora tenho certeza que estou usando a versão 8.6.0.

user<strong i="6">@machine</strong>: which firebase
/usr/local/bin/firebase
user<strong i="7">@machine</strong>: cd /usr/local/bin
user<strong i="8">@machine</strong>: sudo rm firebase
user<strong i="9">@machine</strong>: sudo ln -s /usr/lib/node_modules/firebase-tools/lib/bin/firebase.js firebase
user<strong i="10">@machine</strong>: firebase --version
8.6.0

A palavra _local_ é a chave

Uma instalação global instalará firebase-tools em '/ usr / local / lib / node_modules'. No entanto, o problema destacado pelo OP aponta para um caminho diferente: '/ usr / lib / node_modules / firebase-tools /'.
No primeiro caminho, eu tinha a versão mais recente do firebase-tools 8.6.0, mas a versão 7.0.2 no segundo caminho.

Um firebase -V retornou 7.0.2

Aqui está um comentário relevante (de uma discussão aqui: 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.

O que aconteceu comigo foi npm uninstall firebase-tools , depois me certificando de que tinha a versão mais recente instalada com -g . Agora, firebase -V aponta para o caminho certo com a versão atualizada e o emulador Firebase funciona sem problemas.

Caso ajude, eu tive conflito entre meu npm global [email protected] e meu fio global [email protected] . Excluir minha versão npm global corrigiu meu problema de retornar 7.0.0 de firebase -V

eu estava ficando acima do erro devido à versão de nó diferente usada durante

1. inicialização do projeto (firebase init) => node version => v8.xx
2. projeto em execução (emuladores firebase: start) => node version => v12.xx

Resolvi o problema criando a mesma versão de nó

Você não pode (facilmente). Eu tentaria encontrar um binário semelhante e colocá-lo no mesmo caminho
