不确定为什么我不能运行Rails服务器

Question

I'ma front-end developer looking to get a bit more versed in Rails engineering. I've worked on a few rails projects in the past and my machine was configured to work on those projects. However, I'm trying to set up my own rails app and so far I've gotten the new project created in the correct directory, but when I try to run my server "$ rails server" my localhost:3000 port doesn't show anything, and I receive the following error:

Jon-Haddens-MacBook-Pro-2:app jonhadden$ rails server

Any help would be appreciated.

Answer 1

You're using Rails 2, and the commands for that are quite different. rails server will only start a server in Rails 3 and 4, in Rails 2 this will create a new app called 'server'; you're looking for rails script/server .

You should really start working with Rails 4 - Rails 2 is no longer supported.

Answer 2

Try rails script/server . But you should really look into upgrading rails to a newer version.
