Re: rails new command dies with a strange error

I’m probably wrong with this response as I’ve never attempted a Rails app on windows,  that said, the first thin I’d do is just use the SQLite dB, see if that works. That’s really the only thing that jumps out at me from what you posted, and I’ve no clue why it would want to make another C buried in your Rails app
