电容器:无法加载capacitor.config.json

Question

创建一个带有电容的Ionic 5应用程序，我遇到了这个问题，似乎没有加载capacitor.config.json。

这个问题是在我安装了@codetrix-studio/capacitor-google-auth之后出现的，那时这个项目还没有在android上运行。

{
  "appId": "com.luyou.clauncher",
  "appName": "c-launchpad",
  "bundledWebRuntime": false,
  "npmClient": "npm",
  "webDir": "www",
  "plugins": {
    "SplashScreen": {
      "launchShowDuration": 0
    },
    "GoogleAuth": {
      "scopes": [
        "profile",
        "email"
      ],
      "serverClientId": "xxxxxxxxxxxx-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.apps.googleusercontent.com", // On my project I'm using the real server client id
      "forceCodeForRefreshToken": true
    }
  }
}

在android演播室中，构建进行得很好，但是当您尝试打开应用程序时，它确实会崩溃，如下所示：

capacitor.config.json已经在项目的根路径上了，执行npx cap copy或npx cap sync并不能解决这个问题，但实际上是在复制www文件。由于某些原因，电容配置只是没有被复制。

Answer 1

似乎电容α版本被打破了，所以回到电容2.4.7解决了问题。capacitor.config.json正在正确加载，本机插件正在加载。

Answer 2

“太棒了，谢谢”禤浩焯乐派。降级到电容器2.4.7为我解决了它。

这就是我的package.json的样子：

"dependencies": {
  ...
  "@capacitor/android": "^2.4.2",
  "@capacitor/core": "2.4.7",
  ..
},
"devDependencies": {
  ...
  "@capacitor/cli": "2.4.2",
  ...
}
