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

What solved it for me:

• Open a terminal window
• cd into YOUR_PROJECT/ios
• Remove the build folder with rm -r build
• Run react-native run-ios again

Alternatively, you could open Finder, navigate to YOUR_PROJECT/ios and delete the build folder.

Then run react-native run-ios again.
