Description

Simply trying to run the react-native run-android command returns me this React Native CLI-related error.

• What went wrong: A problem occurred evaluating script.

Failed to parse React Native CLI configuration. Expected running ‘npx.cmd --quiet --no-install react-native config’ command from ‘C:\Users\Master\Desktop\proj\UltimaTentativa’ directory to output valid JSON, but it didn’t. This may be caused by npx resolving to a legacy global react-native binary. Please make sure to uninstall any global ‘react-native’ binaries: ‘npm uninstall -g react-native react-native-cli’ and try again

• Try: Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
