Ok, I'm a noob with rails... so I just set up rails with RVM and created a new project, and when I try to visit a newly created view I'm getting an error 500.
Heres my setup:
OSX 10.6.5
Installed MySQL 64bit
RVM installed ruby 1.8.7 and rails 2.3.8 (no other rails or ruby except for the system ruby) rvm install 1.8.7, rvm use --create 1.8.7#rails2, gem install rails -v=2.3.8
Passenger with Apache gem install passenger, rvmsudo passenger-install-apache2-module
Passenger preference pane
Turned on websharing
I then proceeded to setup a rails project in my development folder called testapp, added it in the passenger preference pane, and then ran script/generate controller Say, defined an action hello, and then created a view in the app/view/say folder called hello.
Now I'm getting a 500 error when visiting myapp.local/say/hello, what am i doing wrong?
UPDATE:
I checked the logs and also tried running using WEBrick instead of passenger and apache. I got thrown back the same errors. I don't think I should post the entire log, should I? But the first error is
no such file to load -- sqlite3
I have not yet setup a db, I was going to use mysql, but I didn't want to install it since I'm not using models yet. Is it a requirement?
UPDATE 2:
So I installed the mysql gem with gem install mysql -- --include=/usr/local/lib (not sure if this is right). I then created a rails app with rails -d mysql myapp. And set the password in the database.yml. I'm getting a new error now:
Unknown database 'myapp_development'
So I have to create a database. Why am I being forced to create a db at all?
Yeah, you need to install sqlite even if you're not using models yet - Rails checks to make sure whatever is specified in database.yml is actually there to use.
Don't access it through passenger, launch it using ruby script/server and check out the error it throws there. Generally those errors are way more descriptive than Passenger because Passenger is probably running your application using the production environment.
Hey Ryan, do you need to Ruby 1.8.7? Why don't you install the latest 1.9.2 and Rails 3? I have the same environment and so far no problems. Here is a link for installing everything you need. Let me know if it helped! http://amerine.net/2010/02/24/rvm-rails3-ruby-1-9-2-setup.html
Salud!

So I'm a rails developer familiar with Rails 3 and 4. I'm taking on a Rails 1.1.2 project, and the first problem I'm having is getting the server running.
I'd really love some help figuring out what I'm missing setting up the environment. When I run script/server, I get:
-bash: script/server: /Users/michael/.rvm/gems/ruby-1.9.3-p545: bad interpreter: Permission denied
This is after noting that at the top of the script/server file, there's an opportunity to define the location of the ruby install with a ruby comment:
#!/Users/michael/.rvm/gems/ruby-1.9.3-p545
At least, this is how I understand it. What should this comment point to? Does this look correct? I've installed ruby 1.9.3 using rvm and installed rails V 1.1.2 through sudo gem install rails. Everything seemed to work fine.
Is this some kind of bash permissions issue? I really don't understand what's going on. Any help would be appreciated!
I believe a rails project that old will require Ruby 1.8.7, so you should start with an older version of Ruby just to be sure. Once you get it running with the older ruby version, you can try 1.9 again, but trying it with 1.8.7 should help you out a bit. Your shebang should be able to do this though:
#!/usr/bin/env ruby
It needs the path of the ruby interpreter, which can be obtained dynamically via the above line.
I'm following Michael Hartl's Ruby on Rails tutorial, and I got stuck at trying to start rails server on my Windows 7 machine.
I'm trying to do this by following instructions in Chapter 1.2.5., i.e. by typing
rails server
However, instead of booting WEBrick, this returns the instructions for usage of 'rails' command. I've been googling this for a while, and some of the answers seem to have implied that something is wrong with the rails gem.
Now, I've found the rails gem folder ("C:\RailsInstaller\Ruby1.9.3\lib\ruby\gems\1.9.1\gems\rails-3.2.3"), and it's empty!
Also when I try
rails -v
it returns "Rails 3.2.16", although I've removed this version of the gem; if I try
gem list
it kept telling me that the version is 3.2.3.
This persisted until I deleted railties version 3.2.16, which resulted in
rails -v
returning 'Rails 3.2.3', but I still can't boot WEBrick.
Any help would be appreciated.
Did you run the installer?
At the time of this writing, I recommend using the Ruby 2.0.0-p353.
http://dl.bintray.com/oneclick/rubyinstaller/rubyinstaller-2.0.0-p353.exe?direct
Save yourself some future gem headaches and install the DevKit too.
http://rubyinstaller.org/downloads/
It should create a folder at C:\Ruby200. Start a new command prompt for the new paths to take affect.
Once Ruby is install, gem install Rails. From your other post, I recommend gem install rails -v 3.2.16
Then execute rails new project_name, then cd project_name. Then run rake db:migrate to create the initial database. At this point, you should be able to run rails server and visit localhost:3000 in your browser.
OK, I've managed to solve my problem.
I've seen a few more people having the same issue, but none of the solutions that I've found helped me, so here's what did it for me, though I'm not 100% sure what exactly was that one thing that actually did it...
I've followed the advice #scarver2 gave in response to my other question, and uninstalled both Rails and Railties gems from my crispy fresh installation of Ruby 1.9.3. (I've installed it using RailsInstaller). Then I've installed Rails 3.2.16 gem by typing
gem install rails -v 3.2.16
and this also installed the corresponding Railties 3.2.16 gem without my intervention.
Then I followed steps from chapters 1.2.3. and 1.2.5. of the tutorial, but making sure that line referencing ruby version in my Gemfile actually corresponds to the version of Ruby that I have installed.
I typed
ruby -v
in the console, to make sure that I have version 1.9.3. indeed. Confirming this, I've edited the Gemfile in my app so it says
ruby '1.9.3'
instead of ruby '2.0.0' line that's used in Listing 1.5. of the tutorial.
After that I've simply went to my app folder, and typed
bundle update
bundle install
in the console, and this time it did not return any errors as it did in my previous attempts. After that, typing
rails server
did what it should have, and my WEBrick server booted, allowing me to access my app on localhost. Yay!
Now, what I think may have gone wrong the last time was either me screwing up the Gemfile, so the gem versions and their dependencies got messed up. I also assume that ineptly trying to fix this by installing and uninstalling different versions of various gems did not quite help. What may have helped was uninstalling Rails and Railties gems, and installing Rails gem again.
My specs are as follow:
Windows 8 64-bit
Ruby 1.9.3
Rails 3.2.12
I installed rails via the RailsInstaller. I have also installed the mysql2 gem. I created a new project that is pre-configured to use mysql e.g.
rails new project_name -d mysql
I then tried to start up the server/WEBrick via
rails server
And I get the following error:
I've tried this using the mysql2 as well as teh mysql gem. Both times I get the same error. When I use the default sqlite then the project starts up fine and I can view it on localhost:3000.
I'm aware that mysql2 used to be a problem on rails, but since mysql isn't working either I'm of the opinion that it's a Windows 8 specific project, surprise surprise.
I'd deff like to use MySQL rather than SQLite. Thanks for anyone that can point me in the right direction!
As a noted error case,
The SO Post says-
"The problem is with mysql. It is a 64 bit installation. Change it to 32bit and it runs fine."
Apart from that, this error may also be the result of some missing gems.
You should try running bundle install before running your server.
Also make sure that gem mysql is added to your gemfile before you do bundle install.
Please update your MySQL to 64bit version. It will fix the problem. Don't forgot to install the Devkit.
I have installed ruby193 and I've installed rails via the command prompt. However, whenever I try the command:
ruby script/server
I get this error:
ruby: No such file or directory -- script/server (LoadError)
I checked my script folder and all it has is a file called rails.
I'm very new to Ruby on Rails and I'm not entirely sure if I've installed everything correctly. Is there an easy way to check what I have installed?
To clarify on the existing answers, ruby script/server is no longer the proper way to start a server in Rails. In Rails 3, we use rails server, which can be shortened to rails s. See the Rails Guides for a more extensive rundown of the Rails 3 command line interface.
Try running rails server or rails s.
If you have Ruby & rails installed properly, then ruby -v would result in the version that you have installed and likewise rails -v would give the rails version installed.
To run a rails server try running rails server or rails s
I am new to Ruby on Rails and am following a tutorial to create a class project.
I can generate a new rails project with
$ rails project
The problem Im having is when I try to start my server, It will generate a project called server:
$ rails server
or
$ rails s
I figured out that I need to install/update rails to 3.0.3 to use this command every time I open terminal. I find myself having to install gems(bundle, etc) every time I need to work on my project.
Is there anyway to save this terminal session or profile for later use?
Is it user error?
Im new to Rails and about the same with terminal.
Any help would be greatly appreciated. I have resorted to leaving my computer and terminal open for about a week...
Welcome on board! - You'll have fun, I found setting up the environment the most difficult thing.
in rails 2 you start the server with ruby script/server.
to upgrade to rails 3 try gem install rails -v=3.0.4
I put the version but it's not a mandatory option.
To uninstall a gem (as rails is) is gem uninstall gemname -v=x.x.x. -
gem list will tell you the version of each gem.
I hope you've got rvm, if not I strongly sugget you to install it, this will allow you not only to use different versions of ruby but also to set different gemsets, therefor one each project, you'll find it useful.
Once in rails 3 you can use bundler, have a look at this episode of railscasts, by the way this is a very good site, but you may know it already.
another edit...
I don't know the behavior you're describing, looks like something is wrong with your environment, but I need to know if you have rvm to solve this, if so try rvm list and rvm gemset, With the first you get the list of installed ruby, you can switch between them with rvm 1.9.2 i.e. and rvm 1.9.2#gemdirname with the gemdir coming from the second list. You should find your configuration in one of those list.
Hi if you are using rails 2.8 or lesser use this to start the server
ruby script/server
rails new project is for new rails project n rails s is for starting server
