Hi folks,

I’m having trouble getting gems to install rails. It just keeps asking  
me which version of thin I want to install. Until I choose skip or  
cancel, in which case I’m told that something has gone wrong.

Any advice?

Thanks kindly,

Tommy

PS: Gems is 0.94.

Have you tried using a capital ‘Y’ when responding to ‘[Yn]’?

The try installing both thin and rails again.

sudo gem update --system
