Question

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、npminit（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、npminstall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":"nodenode_modules/react-native/local-cli/cli.jsstart","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。。。）
