An error is reported after running npm run watch
Error: error:0308010C:digital envelope routines::unsupported
Solution: Open the legacy OpenSSL provider, add the following command in package.jsonthe file scripts, the Windows solution is as follows:
set NODE_OPTIONS=–openssl-legacy-provider &&
The changed package.json file is as follows:

}
}
Under Linux, it is as follows:export NODE_OPTIONS=--openssl-legacy-provider
Guessing the cause of the error : using a higher version of Node.js, and then using webpack4, my Node.js is v18.15.0
