无法将STDOUT重定向到/home/ubuntu/workspace/shared/log/puma.stdout.log（RuntimeError）

Question

I have this error when I try to start my rails server. Before I pulled from the repo I am working from, I had no problems with running the server. I am using C9 IDE, but I don't think that's the issue.

[1708] Puma starting in cluster mode...
