I made a simple react native demo on one computer, using react-native-cli, and then put it on github. Now I clone the project on another computer, and after npm install, react-native run-android reports an error when installed on the simulator. Is there anything that needs to be set up? This clone project computer has run other react-native projects before. Is there any impact?
Now Error app:installDebugException in thread "Device List Monitor" java.lang.NullPointerException

I don’t know about you. Anyway, if ios reports an error, just upgrade the Xcode version directly. You can also try upgrading your debugging tools
The description is not very clear. You need to know which files you uploaded to github. If you only ignore the node_modules file, npm install will be no problem after cloning.
