Whenever I try to create the files and folders the project asks me to, the page goes blank and something bugs. After I refresh the page the files are created but i have to reinstall the gemfiles in the command directory.
please help

It also tells me the folder already exists when I try to create it. But it is not there…

The same problem with the db/migrate file. It should be there but it is not. This is so frustrating!
