Command `run-android（ios）` unrecognized.

react-native ,首先，我想要引入轮播图效果，然后找了一个

 react-native-swiper

执行了以下语句

npm uninstall react-native-swiper –save / yarn add react-native-swiper

居然报错了-

Command `run-android` unrecognized. Make sure that you have run `npm install` and that you are inside a react-native project.

照着提示执行了

npm install / yarn

react-native run-android 还是报错，依旧很让人惆怅~！！！~~~~

结果网上看了一大堆乱七八糟的解决方法，没有效果

.......

找着看到了这个一个国外网站写着这么几句话

4、Command `run-ios` unrecognized. Did you mean to run this inside a react-native project?

npm install -g react-native-cli

npm install --save react-native@latest

照着敲进去了

npm install -g react-native-cli / npm install -g yarn react-native-cli

npm install --save react-native@latest / yarn add react-native@latest

react-native init 

之后呢，居然可以了，上天保佑无bug~！！！！！！

好了问题解决了，记录一下

报错：

Command `run-android` unrecognized. Make sure that you have run `npm install` and that you are inside a react-native project.

解决方法：

npm install -g react-native-cli / npm install -g yarn react-native-cli

npm install --save react-native@latest / yarn add react-native@latest

react-native init
