部署时出现 Firebase 错误，.env 文件“HOST 以保留前缀开头”

Question

Firebase 部署过去一直有效，但今天当我对规则和一些功能进行简单更新后尝试部署时，我收到此错误：

\n

Error: Failed to load environment variables from .env.:\n- Error Key FIREBASE_AUTH_EMULATOR_HOST starts with a reserved prefix (X_GOOGLE_ FIREBASE_ EXT_)\n- Error Key FIREBASE_STORAGE_EMULATOR_HOST starts with a reserved prefix (X_GOOGLE_ FIREBASE_ EXT_)\n- Error Key GCLOUD_PROJECT is reserved for internal use.\n

\n

这是错误的整个上下文：

\n

\xe2\x9c\x94  functions: Finished running predeploy script.\ni  firebase.storage: checking storage.rules for compilation errors...\n\xe2\x9c\x94  firebase.storage: rules file storage.rules compiled successfully\ni  firestore: reading indexes from firestore.indexes.json...\ni  cloud.firestore: checking firestore.rules for compilation errors...\n\xe2\x9c\x94  cloud.firestore: rules file firestore.rules compiled successfully\ni  functions: ensuring required API cloudfunctions.googleapis.com is enabled...\ni  functions: ensuring required API cloudbuild.googleapis.com is enabled...\n\xe2\x9c\x94  functions: required API cloudfunctions.googleapis.com is enabled\n\xe2\x9c\x94  functions: required API cloudbuild.googleapis.com is enabled\nError: Failed to load environment variables from .env.:\n- Error Key FIREBASE_AUTH_EMULATOR_HOST starts with a reserved prefix (X_GOOGLE_ FIREBASE_ EXT_)\n- Error Key FIREBASE_STORAGE_EMULATOR_HOST starts with a reserved prefix (X_GOOGLE_ FIREBASE_ EXT_)\n- Error Key GCLOUD_PROJECT is reserved for internal use.\n

我在测试中使用一个 .env 文件来指向模拟器的位置，就是这样：

\n

FIRESTORE_EMULATOR_HOST='0.0.0.0:8080'\nFIREBASE_AUTH_EMULATOR_HOST='0.0.0.0:9099'\nFIREBASE_STORAGE_EMULATOR_HOST='0.0.0.0:9099'\nGCLOUD_PROJECT='PROJECTNAME'\n

\n

这是否有原因导致现在才导致错误？当我删除它并部署它时，它就可以工作了。

您只需更改环境变量的名称即可。将 FIREBASE_DATABASE_URL 更改为 FB_DATABASE_URL
