Rails Webrick强制退出：未初始化的常量WebConsole :: Railtie :: Middleware（NameError）

Question

So I'm a newbie in ruby trying to start up webrick for the first time. I just recently fixed the segmentation fault error with the mysql2, and got hit with this new exit issue. Here's the command line readout:

G:\\Ruby Development\\simple_cms>

G:\\Ruby Development\\simple_cms>rails server

=> Booting WEBrick

=> Rails 4.2.1 application starting in development on http://localhost:3000

=> Run rails server -h for more startup options

=> Ctrl-C to shutdown server

Exiting

From what I understand so far I am loading the server up at least. so this isn't a part of the segmentation fault, right?

My gemfile includes web-console 2.1.2. Also, I've ran 'bundle install' just in case. Any insight into this error? Let me know if any more information is needed.

Answer 1

There are two rails executables. Your PATH is pointing you to the wrong one. Type 'which rails': you should get "~/bin/rails", a stub that railties puts in your home directory. If you get something else, rename the rails executable there and try again.
