React本机版本不匹配错误

Question

我正在尝试使用以下命令运行一个react本机应用程序。

npm run android

我得到以下错误。

​

​

im使用nvm - nvm use stable

现在使用节点v8.9.4 (npm v4.6.1)

**package.json**

{
  "name": "client",
  "version": "0.1.0",
  "private": true,
  "devDependencies": {
    "react-native-scripts": "1.11.0",
    "jest-expo": "23.0.0",
    "react-test-renderer": "16.0.0"
  },
  "main": "./node_modules/react-native-scripts/build/bin/crna-entry.js",
  "scripts": {
    "start": "react-native-scripts start",
    "eject": "react-native-scripts eject",
    "android": "react-native-scripts android",
    "ios": "react-native-scripts ios",
    "test": "node node_modules/jest/bin/jest.js --watch"
  },
  "jest": {
    "preset": "jest-expo"
  },
  "dependencies": {
    "expo": "^23.0.4",
    "react": "16.0.0",
    "react-native": "0.50.3"
  }
}

另一个不同的解决方案建议重新运行构建过程，因为可能存在一些干扰，但这对我不起作用。

Answer 1

我自己设法解决了这个问题。错误消息显示了react-native版本的0.50.3。

但从https://facebook.github.io/react-native/versions.html可以看到，最新的版本是0.52。

因此，我更新了json包以反映这一点。

  "dependencies": {

    "react-native": "0.52"
  }

然后我删除了npm模块并重新运行npm install。这解决了我的问题。

更新package.json react-native依赖项以反映最新版本。

Answer 2

我也有同样的问题，可汗给了我们正确的解决方案。

我在这里为那些需要修复的人提供了package.json：

{
  "name": "project",
  "version": "0.1.0",
  "private": true,
  "devDependencies": {
    "react-native-scripts": "1.11.0",
    "jest-expo": "25.0.0",
    "react-test-renderer": "16.0.0"
  },
  "main": "./node_modules/react-native-scripts/build/bin/crna-entry.js",
  "scripts": {
    "start": "react-native-scripts start",
    "eject": "react-native-scripts eject",
    "android": "react-native-scripts android",
    "ios": "react-native-scripts ios",
    "test": "node node_modules/jest/bin/jest.js --watch"
  },
  "jest": {
    "preset": "jest-expo"
  },
  "dependencies": {
    "expo": "^25.0.0",
    "react": "16.0.0",
    "react-native": "0.52"
  }
}
