输入 npm start 时终端上没有二维码

Question

我输入命令 create-react-native-app <My package name>

然后我输入npm start我可以在我的终端上看到 QRCode

但是当我npm run eject为我的项目打字时

我npm start再打字。我的终端上不再显示 QRCode。

我在寻找一些答案仍然无法解决它。它让我很困惑。

这是我的环境：Mac OS:10.13.4

  "name": "TestMovie2",
  "version": "0.1.0",
  "private": true,
  "devDependencies": {
    "babel-preset-react-native-stage-0": "^1.0.1",

    "jest": "^22.4.3",
    "jest-react-native": "^18.0.0",
    "react-test-renderer": "16.3.0-alpha.1"
  },
  "scripts": {
    "start": "react-native start",
    "android": "react-native run-android",
    "ios": "react-native run-ios",
    "test": "jest"
  },
  "jest": {
    "preset": "react-native"
  },
  "dependencies": {
    "@shoutem/animation": "^0.12.2",
    "@shoutem/ui": "^0.23.4",

  }
}

希望你已经解决了这个问题，但仍然面临这个问题的任何人都可以输入expo start而不是 npm start
