As shown in the figure, it
probably means that require('ReactNative') failed, there are multiple people with this name, one of them is in the...\src\... directory, I checked this directory and found the directory doesn't exist at all.
After testing, after deleting this project (zixiaoapp), a brand new project of react-native init zixiaoapp will still report this error, so it is guessed that nodejs has cached the compilation result.
npm start -- --reset-cache
executes the command to clear the cache again. It
seems that there is another command called npm cache clean
