部署、模拟器启动和默认 github 部署管道时 Firebase Web 框架检测错误

Question

当我尝试使用

firebase deploy

命令部署我的 Angular Web 应用程序时，使用

firebase emulators:start

命令启动 firebase 模拟器，或者执行合并管道上的默认 github 部署时，我总是遇到相同的错误：

Could not determine the web framework in use.

Error: Unable to detect the web framework in use, check firebase-debug.log for more info.

我看到很多帖子提到，这是身份验证的问题，您应该在 firebase cli 中注销并再次登录。就我而言，这没有帮助。

我还尝试重新运行

firebase init

命令，但这没有帮助。 这是我的 firebase 配置文件。除了公用文件夹位置之外，我没有更改任何内容：

firebase.json

    "rules": "firestore.rules",

Answer 1

经过更多故障排除后，我发现了问题。

结果，我的

firebase.json

是用错误的参数生成的。

将构建“源”位置的名为“public”的参数添加到托管部分，因此无法找到应用程序代码。

这是正确的托管配置：

"hosting": {
    "public": "dist",
    "ignore": [
      "firebase.json",
      "**/.*",
      "**/node_modules/**"
    ],
    "frameworksBackend": {
      "region": "europe-west1"
    }
  }
