我正在使用 Firebase 运行我的应用程序的后端。当我尝试使用 \n 运行后端时，firebase emulators:start --inspect-functions它说

\n

节点 v: 18.13.0
\nFirebase-tools v: ^11.18.0
\nFirebase-functions v: ^4.2.0

\n

Answer 1

这里的问题可能是您正在为环境变量键使用保留的 Firebase 名称。您可以查看Firebase Config Env文档。

任何以 FIREBASE 一词开头的键都被保留。

我遇到了同样的问题，我可以通过更改环境变量的名称来解决它。

我希望这有帮助。祝你好运！:)

任何原因都可能发生这种情况：

仔细检查该文件是否包含以下行：

FIREBASE_API_KEY=XYZ123 
FIREBASE_AUTH_DOMAIN=mydomain.firebaseapp.com 
FIREBASE_DATABASE_URL=https://mydatabase.firebaseio.com 
etc...

检查 .env 文件是否已在您的gitignore或.npmignore. 如果忽略该文件，则不会加载环境变量。并确保设置变量时 = 周围没有空格。
