React Native: A red screen reports connection failure, reactnative

Recently, the mobile project team switched to React Native to develop applications under my own leadership. I have never touched it before. After a few weeks, I found that this is the case. I can still use small toys. Today, the Android girl cannot solve the problem in Windows. After some inquiries, she found another strange problem. In WebStorm, she can edit and run the problem to the simulator normally, the use of react-native run-android does not work. After some tossing, the visual test showed that her environment variable encountered a problem, causing the Server environment to fail to start and open the package. after reading the following content in json, the solution is as follows:

1. react-native run-android command to compile and install

2. Enable npm start to run Server

 

PS: I used android many years ago and hate Eclipse. Now I am working on iOS.
