我在app / functions / index.js中有一个Firebase规则文件 我试图通过此命令firebase部署--only数据库部署数据库规则，但是当我运行此命令时，它会给出此错误 错误：加载firebase.json时出错：
解析错误：functions / index.js不是受支持的配置文件类型
这是我运行firebase init命令时创建的firebase.json文件
{
"database": {
"rules": "functions/index.js"
}
}
这是我的index.js文件

有关如何格式化规则的示例，请参阅Firebase CLI文档的Deployment部分以及Firebase Web Codelab部分。 firebase.json文件指定：
{
"database": {
"rules": "database-rules.json"
},
...
}
在同一目录中，有一个database-rules.json文件，其中包含上传的规则配置。
我不是百分百确定，但很可能规则配置文件必须采用JSON格式，具体取决于您收到的错误消息：Parse Error: functions/index.js is not of a supported config file type。

您似乎混淆了可以使用CLI发送到Firebase服务器的两种类型的文件：
Firebase数据库安全规则定义数据库服务器本身如何确保所有读/写操作都有效和授权。它通过JSON文件配置，通常称为rules.json或database-rules.json。 format of these security rules is documented here。
Firebase的云功能是在Google的服务器上运行的JavaScript功能，用于响应Firebase项目中发生的事件。代码通常位于名为index.js的文件中。 Functions are documented here
您告诉Firebase CLI部署数据库安全规则（上面的选项1），但是传递了一个定义云功能的文件（上面的选项2）。由于functions/index.js不是有效的JSON文件，因此该工具无法部署它。
要做的第一件事是从rules删除错误的firebase.json定义：
{
"database": {
"rules": "database-rules.js"
}
}
如果您尝试仅部署项目的云功能，请使用firebase deploy --only functions。
如果您尝试部署数据库安全规则，请确保您拥有有效的database-rules.json并运行firebase deploy --only database。
