Rails Server immediately exists start up

Question

Hi I'm new to Rails and have absolutely no idea why rails server won't work. I have no doubt the answer is in all this code below but I'm completely stuck. Any ideas?

Notice: server is listening on all interfaces (0.0.0.0). Consider using 127.0.0.1 (--binding option)
=> Ctrl-C to shutdown server

Answer 1

The config/secrets.yml file is invalid.

YAML is whitespace sensitive so make sure to check that there are no leading whitespaces. If you aren't sure if your YAML file is valid, try pasting it into this yaml validator http://yamllint.com/ to see if its valid.

我恢复了Gemfile的最新版本后解决了问题
