react-native start的时候出错

[jianfengye]

git clone下来代码，进入root

➜  ZhiHuDaily-React-Native git:(master) npm install
➜  ZhiHuDaily-React-Native git:(master) react-native start
Command `start` unrecognized. Did you mean to run this inside a react-native project?

如何处理。。。

你好，开发环境都配置好了吗？

[jianfengye]

开发环境都配置好了，我自己创建的AwsomeProject是可以运行起来的。

但是使用awsomeProject和ZhihuDaily项目的时候有一个不通就是npm的源不同

在跑ZhihuDaily项目的时候，我用的是淘宝的npm

不知道这个有没有影响？

[race604]

react-native run-android 呢？

[jianfengye]

➜  ZhiHuDaily-React-Native git:(master) ✗ react-native run-android
Command `run-android` unrecognized. Did you mean to run this inside a react-native project?

[jianfengye]

真是。。。。看来是node_module的问题

[zzyyppqq]

[zzyyppqq]

是这个原因吗

[jorry]

我也遇到这个问题，怎么解

[jiangqingbo]

运行 react-native run-android 之前先运行 npm install , 解决了这个问题。

[easternHong]

大神们,可以配置使用全局的node_modules吗,每一个工程目录下面都有一个node_modules文件夹,文件基本相同.

[chocoluffy]

@easternHong 配置全局通常是两种情况， 一个是给开发工具dev tool比如grunt, http-server, browser-sync等为的是开发的方便， 或者第二种接口的command line tool比如aws\react-native等等， 感觉大致上还是工具类的居多， 框架类的还是通过node_modules来安装更新， 毕竟npm install可以根据package.json规定的版本区间自动更新符合要求的版本号~个人感受哈， 欢迎补充!

npm installl
react-native start
react-native run-android

[PayneJay]

npm installl
react-native start
react-native run-android
这三步之后完美的运行起来了，赞👍
