在Rails 3中启动rails服务器

Question

I have created a new rails project with the command:

rails project_name

but now in that project if I run:

rails server

I just creates a new project call server, it doesn't start webrick.

How do I start the server and get rails running?

Answer 1

Old versions or rails are bugging you. Deinstall them using gem uninstall rails . I recommend using RVM with gemsets to create separate environments for each project.

Answer 2

You're mixing Rails 2 and Rails 3 commands. By the looks of it, you're using Rails 2, which means starting the server would be script/server , not rails server

Answer 3

Step by Step rails server Installation :

1. Create Gemset using " rvm create gemset "
2. rails new
3. goto rails app directory "cd/"
4. gem install rails
5. echo "rvm use " > .rvmrc for example : echo "rvm use 1.9.3-p385@mygemset" > .rvmrc
6. run - "bundle install"
7. rails s

yeah, nothing to do more... :)

Answer 4

I had this problem on Ubuntu and found that I had rails 3 installed with gem and rails 2 installed with apt. Removing the apt version solved the issue:

sudo apt-get remove rails
