react-native启动意外令牌

Question

使用react-native时,我在启动命令时遇到错误.第63行的文件 projectName /node_modules/@babel/core/lib/transformation/file/file.js给出了错误

constructor(options, {
                     ^

SyntaxError: Unexpected token {
    at exports.runInThisContext (vm.js:53:16)
    at Module._compile (module.js:374:25)
    at Module._extensions..js (module.js:417:10)
    at Object.require.extensions.(anonymous function) [as .js] (/home/cread/WHOOP-ReactNative/whoopApp/node_modules/babel-register/lib/node.js:152:7)
    at Module.load (module.js:344:32)
    at Function.Module._load (module.js:301:12)

    at Module._compile (module.js:410:26)

这是我的package.json文件

{
  "name": *name*,
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node node_modules/react-native/local-cli/cli.js start",
    "test": "jest"
  },
  "dependencies": {
    "react": "16.3.0-alpha.2",
    "react-native": "0.54.2",
    "react-native-elements": "^0.19.1",
    "react-native-keyboard-aware-scroll-view": "^0.5.0",
    "react-native-modal-dropdown": "^0.6.2",
    "react-native-sound": "0.10.9",
    "react-native-vector-icons": "^4.5.0",
    "react-navigation": "^1.5.8"
  },
  "devDependencies": {
    "babel-jest": "23.0.0-alpha.0",
    "babel-preset-react-native": "4.0.0",
    "jest": "22.4.2",
    "react-test-renderer": "16.3.0-alpha.2"
  },
  "jest": {
    "preset": "react-native"
  }
}

我已经尝试删除我的node_modules文件,清除npm缓存,并重新安装但无济于事.问题似乎出现在cli.js文件中.

我使用的是react-native和nodejs的最新版本.不幸的是,我需要回到版本8.11.2.在我的情况下,它已得到解决.我删除了node_modules目录.

$ rm -rf node_modules
$ nvm install 8.11.2
$ nvm use 8.11.2
$ npm install react-native@0.54.1
