反应本机package.json版本

Question

我使用create-react-native-app命令创建了一个一个月前创建的React本机项目。

package.json内容如下：

{
  "name": "TestApp2",
  "version": "0.1.0",
  "private": true,
  "devDependencies": {
    "react-native-scripts": "1.1.0",
    "jest-expo": "~19.0.0",
    "react-test-renderer": "16.0.0-alpha.12"
  },
  "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": "^19.0.0",
    "react": "16.0.0-alpha.12",
    "react-native": "^0.46.1"
  }
}

当我今天创建项目时，package.json如下所示：

{
  "name": "NewApp",
  "version": "0.1.0",
  "private": true,
  "devDependencies": {
    "react-native-scripts": "1.5.0",
    "jest-expo": "^21.0.2",
    "react-test-renderer": "16.0.0-alpha.12"
  },
  "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": "^21.0.0",
    "react": "16.0.0-alpha.12",
    "react-native": "^0.48.4"
  }
}

请注意，react-native-scripts、jest-expo和expo的版本是不同的。我的问题是，我如何升级版本？我应该手动更改版本号吗？

我试着用：

$ npm install -g react-native-git-upgrade
$ react-native-git-upgrade

但它并没有升级版本。

我也试过：

$ npm update
$ react-native upgrade

但这两个命令都不更新版本。

Answer 1

只需手动更新package.json文件和重新运行的npm install中的版本即可。

Answer 2

因为您使用的是世博，所以您也可以使用它的升级功能。

所以只需在根目录中运行expo upgrade，看这里的世博博士

Answer 3

{

"react-native-scripts": "1.1.0",
"jest-expo": "~19.0.0",

},

尝试使用新版本编辑，并在您的项目中运行"rm -rf node_modules && npm安装“！
