I am facing this error while creating bundle of react-native app.

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

回答1:

To solve my issue I have run command with --force option.

npm install -i -g --force react-native-cli

This issue was raise due to configure old project with old react-native version. and then trying to run latest react-native ver with new Project.

回答2:

install with npx run on windows 10

npx react-native run-android

on linux

npx react-native start

回答3:

I resolved the issue in my Mac using

npx react-native start

回答4:

For me, I installed the wrong package.

Instead of this:

npm i -g react-native

Make sure you do this:

npm i -g react-native-cli

回答5:

I think that's about version of react-native-cli.

You should try to update.

npm i -g react-native-cli

回答6:

I can't comment so use npm install -i -g --force react-native-cli as stated by Punita. It works when it comes to fixing the SHA-1 issue.

But please don't use sudo for any npm related things. thanks.
