What is the meaning of 'No bundle URL present' in react-native?

Question

When I run a react-native project, I get a error no bundle URL present , but I don\'t know what mistakes I do, I was very confused.

Answer 1

make sure you have .jsbundle in your your project

Add

react-native bundle --dev false --entry-file index.js --bundle-output ios/main.jsbundle --platform ios

in your react native code try to reopen the project
