react-native android 找不到项目错误

Question

我正在尝试使用 react-native cli 创建一个 react-native 项目。我用来创建项目的命令

npx react-native 初始化测试

在此之后，如果我尝试运行这个应用

cd 测试 & npx react-native 运行-android

但是我得到这个错误：

错误 Android 找不到项目。你确定这是一个 React Native 项目吗？如果您的 Android 文件位于非标准位置（例如不在 'android' 文件夹内），请考虑设置 project.android.sourceDir 选项以指向新位置。

我在根项目中有 android、ios 文件夹，节点版本是 16.15.0

这是我的项目json:

{
  "name": "test",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "android": "react-native run-android",
    "ios": "react-native run-ios",
    "start": "react-native start",
    "test": "jest",
    "lint": "eslint ."
  },
  "dependencies": {
    "react": "17.0.2",
    "react-native": "0.68.2"
  },
  "devDependencies": {
    "@babel/core": "^7.12.9",
    "@babel/runtime": "^7.12.5",
    "@react-native-community/eslint-config": "^2.0.0",
    "babel-jest": "^26.6.3",
    "eslint": "^7.32.0",
    "jest": "^26.6.3",
    "metro-react-native-babel-preset": "^0.67.0",
    "react-test-renderer": "17.0.2"
  },
  "jest": {
    "preset": "react-native"
  }
}

问题出现在glob@7.2.2 发布之后。按照以下步骤重新编译项目。

清除node_modules
将此添加到 package.json “决议”：{“glob”：“7.2.0”}
使用 npm install

如果这不起作用，请尝试此命令

" 纱线添加 glob@7.2.0"

我试过调试问题。我将我的旧项目与我现在正在创建的项目进行了比较。如果我尝试在新的上输入 npx react-native config，这将显示：

  "project": {
"ios": {
  "sourceDir": "C:\Users\robby\testingproject\ios",
  "folder": "C:\Users\robby\testingproject",
  "pbxprojPath": "C:\Users\robby\testingproject\ios\testingproject.xcodeproj\project.pbxproj",
  "podfile": "C:\Users\robby\testingproject\ios\Podfile",
  "podspecPath": null,
  "projectPath": "C:\Users\robby\testingproject\ios\testingproject.xcodeproj",
  "projectName": "testingproject.xcodeproj",
  "libraryFolder": "Libraries",
  "sharedLibraries": [],
  "plist": [],
  "scriptPhases": []
},
"android": null

} }

在我的旧项目中：

"project": {
"ios": {
  "sourceDir": "C:\Users\robby\SwaPH\ios",
  "folder": "C:\Users\robby\SwaPH",
  "pbxprojPath": "C:\Users\robby\SwaPH\ios\SwaPH.xcodeproj\project.pbxproj",
  "podfile": "C:\Users\robby\SwaPH\ios\Podfile",
  "podspecPath": null,
  "projectPath": "C:\Users\robby\SwaPH\ios\SwaPH.xcodeproj",
  "projectName": "SwaPH.xcodeproj",
  "libraryFolder": "Libraries",
  "sharedLibraries": [],
  "plist": [],
  "scriptPhases": []
},
"android": {
  "sourceDir": "C:\Users\robby\SwaPH\android",
  "isFlat": true,
  "folder": "C:\Users\robby\SwaPH",
  "stringsPath": "C:\Users\robby\SwaPH\android\app\src\main\res\values\strings.xml",
  "manifestPath": "C:\Users\robby\SwaPH\android\app\src\main\AndroidManifest.xml",
  "buildGradlePath": "C:\Users\robby\SwaPH\android\build.gradle",
  "settingsGradlePath": "C:\Users\robby\SwaPH\android\settings.gradle",
  "assetsPath": "C:\Users\robby\SwaPH\android\app\src\main\assets",
  "mainFilePath": "C:\Users\robby\SwaPH\android\app\src\main\java\com\swaph\MainApplication.java",
  "packageName": "com.swaph",
  "packageFolder": "com\swaph",
  "appName": "app"
}

}

据我所知，android代表根文件夹中的android文件夹。没有项目检测到它，我们无法运行 npx react-native run-android 或 react-native run-android。我还没有找到任何有效的修复方法。

我也遇到了同样的问题，所以我在 r/reactnative 上创建了一个讨论帖，有人提供了解决方案。不知道为什么，但它对我有用。解决方案是：

删除node_modules
将此添加到 package.json: "resolutions": { "glob": "7.2.0" }
使用 yarn 或 npm 安装 node_modules
