如何给现有工程初始化一个react-native环境的package.json

Answer 1

1、进入你工程的根目录 2、npm init （这个工作跟cocoapods的podfile文件初始化有点像）-> 根据提示输入工程的package.json的内容。 3、npm install 经过上述的步骤之后工程根目录底下就有了react-native的环境了。 然后此时要导入的redux框架，这时候只要往dependcies中增加: "name": "RNIntergrationDemo", "version": "0.0.1", "private": true, "scripts": { "start": "node node_modules/react-native/local-cli/cli.js start", "test": "jest" }, "dependencies": { "react": "15.4.1", "react-native": "0.39.2", "redux":"3.6.0" }, "devDependencies": { "babel-jest": "18.0.0", "babel-preset-react-native": "1.9.1", "jest": "18.1.0", "react-test-renderer": "15.4.1" }, "jest": { "preset": "react-native" } （然后接着时通过cocoapods导入。。。）
