 * Scusami ma non capisco proprio questo :
    WordPress installation needs access 
   to the php functions exec and shell_exec. Your dev server needs access to npm
   6 or higher to develop React apps.
 * Potresti aiutarmi? 🙁

 * Hello lidia,
 * if your server doesn’t have access to `shell_exec` and `exec`, ReactPress can’t
   execute the commands, it needs to create React apps.

 * Yes, but I don’t understand how to get to this. I’m really confused, I’m stuck
   on this.

 * Is this a local development server or a server provided by a hoster?
 * For the local development server check the configuration.
 * For the later contact your hosting provider.

 * I created the app following your tutorial, I used virtual machine. Then I imported
   everything into my site on aruba through the all-in-one migration plugin.The 
   app goes to start but the build doesn’t work

 * It seems that you need to talk to Aruba to activate these `exec` and `shell_exec`.
 * And try to upload your React app by hand, according to the documentation.
    Maybe
   this fixes things

 * Hello,
    Aruba doesn’t want to give me the permits for security reasons. I tried
   to load the app manually but nothing. Thanks anyway

 * Did you try uploading your react according to the [documentation](https://rockiger.com/en/easily-embed-react-apps-into-wordpress-with-reactpress-plugin/)?
 * Try uploading your app with ftp, without any wordpress plugins. You need to create
   a new React app on your live system. Use the exact same name and this time choose“
   Deploy an already build app (Usually on a server).” – This is key.
