我已经删除了 node_modules然后重新npm install

我的pkg.json文件

{
    "name": "ReactNativeWeb",
    "version": "0.0.1",
    "private": true,
    "scripts": {
        "start": "node node_modules/react-native/local-cli/cli.js start",
        "test": "jest"
    },
    "dependencies": {
        "babel-core": "^6.25.0",
        "babel-loader": "^7.0.0",
        "babel-preset-es2015": "^6.24.1",
        "babel-preset-react": "^6.24.1",
        "react": "^16.0.0-alpha.6",
        "react-dom": "^15.6.1",
        "react-native": "^0.44.0",
        "react-native-web": "0.0.103",
        "webpack": "^2.6.1"
    },
    "devDependencies": {
        "babel-jest": "20.0.3",
        "babel-preset-react-native": "2.0.0",
        "jest": "20.0.4",
        "react-test-renderer": "^16.0.0-alpha.6",
        "webpack-dev-server": "^2.4.5"
    },
    "jest": {
        "preset": "react-native"
    }
}

参考https://stackoverflow.com/questions/43798359/react-native-dev-server-returned-500

package.json文件都一致了。

还是报错unable to resolve module react/lib/ReactPropTypes
