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

first close the simulator, then run these on terminal

npm install

react-native run-ios

Answer 2

Solution --> npm start then open new Terminal and go to your project path and then hit react-native run-ios it works for me

Answer 3

check your network proxy , better shut it down.

or u should find an other way to maintain the packager server

Answer 4

Execute the below command:

killall -9 node
rm -rf ios/build
react-native run-ios

it will open launchpackager.command and the application will install on the ios simulator

Answer 5

Solve the error No bundle URL present by:

• Running the following command in your project root directory to delete the iOS build directory, and to kill other React Native sessions (assuming they're running on default port 8081) before re-building:

rm -rf ios/build/; kill $(lsof -t -i:8081); react-native run-ios

• Update your React Native workflow to avoid these error occur by combining the above combination of commands into an alias and appending it to your Bash config file .bashrc with this command:

echo "alias rni=\"kill \$(lsof -t -i:8081); rm -rf ios/build/; react-native run-ios\"" >> ~/.bashrc; source ~/.bashrc

Now you can run React Native iOS build (without worrying about some of the common red error screens of death appearing) with a simple alias shortcut:

rni

Answer 6

check your 'localhost' key at NSExceptionDomains dict in info.plist

if it doesn't exist, it causes error.
