Hey,

I am so stoked to learn rails. i am on an iMac so i know it's pre- installed. I have installed rubystack.

I would like to know how to start my project etc. I have tried a number of tutorials including creating a simple blog from the rails.org site but i fall down every time at, what i think is the same place.

Yesterday i got as far as getting the "Welcome aboard" page running, which i presume means my servers etc are on.

Today, however, i started the server and if i didn't get this message: "/Applications/rubystack-1.6-0/ruby/bin/.ruby.bin: No such file or directory — scripts/server (LoadError)"

i got others such as: the "welcome aboard" page which goes mental if you click the drop down link at the top. it says "something went wrong and we have been notified" or something like that.

basically i need some help, please!

Hi Brad,

I have never used Mac, so essentially can’t you much. But you seem to mistyping “script/server” as “scripts/server”, ie, you should use script (singular)

Thanks, Abhinav

Hey,

Thanks for your reply. i just changed it to script/server and got this: Rails requires RubyGems >= 1.3.1. Please install RubyGems and try again: http://rubygems.rubyforge.org

I am pretty sure the gems were there yesterday and i dont think i did anything that would have got rid of them.

Brad

RubyGems might be there, but not the appropriate version necessarily.

On command prompt do this

gem -v If its < 1.3.1 then, install >= 1.3.1 as suggested by the error message.

Thanks, Abhinav

Wahey! ok, my server is running.

I started this tutorial: http://guides.rubyonrails.org/getting_started.html#creating-a-new-rails-project

when i get to rake db:create it tells me that the mysql.sock (i think thats it) is missing or not there and to install it.

In my /Applications/rubystack-1.6-0/mysql/tmp/mysql.sock folder, it's definiteley there.

im still confused but getting there!

Thanks, Abhinav

Thanks for your reply. I had a look at my database.yml file and the socket path is correctly referenced.

i did rake db:create and got this:

(in /Applications/rubystack-1.6-0/projects/rubystack) Missing the Rails 2.3.2 gem. Please `gem install -v=2.3.2 rails`, update your RAILS_GEM_VERSION setting in config/environment.rb for the Rails version you do have installed, or comment out RAILS_GEM_VERSION to use the latest version installed.

so i did what it told me and entered this: gem install -v=2.3.2 rails

and i got this back: WARNING: Installing to ~/.gem since /usr/local/ lib/ruby/gems/1.8 and     /usr/local/bin aren't both writable. WARNING: You don't have /Users/bradbucceri/.gem/ruby/1.8/bin in your PATH,     gem executables will not run.

You should install any gem with sudo example: sudo gem install rails

Anyway, I guess, you generated the application you are working one with a different rails version than it is currently installed. So I think, updating RAILS_GEM_VERSION with the correct version will be much simpler. Try that. Or if it is just a sample app, discard it, and generate a new one.

Thanks, Abhinav

ok, so i entered this sudo gem install -v=2.3.2 rails

it gave me this:

Successfully installed actionmailer-2.3.2 Successfully installed activeresource-2.3.2 Successfully installed rails-2.3.2 3 gems installed Installing ri documentation for actionmailer-2.3.2... Installing ri documentation for activeresource-2.3.2... Installing ri documentation for rails-2.3.2... Installing RDoc documentation for actionmailer-2.3.2... Installing RDoc documentation for activeresource-2.3.2... Installing RDoc documentation for rails-2.3.2...

so i then tried this again: rake db:create

and it gave me this:

(in /Applications/rubystack-1.6-0/projects/rubystack) !!! The bundled mysql.rb driver has been removed from Rails 2.2. Please install the mysql gem and try again: gem install mysql. rake aborted! no such file to load -- mysql

(See full trace by running task with --trace)

Please do what it says, install mysql gem. Also using Internet search for such simple problems does help.

Thanks, Abhinav

11

Yeah, i have tried installing the gem but it wont work. it keeps giving me the last error that i posted above.

brad

12

Instead of using rake to install mysql gem, use “sudo gem install mysql”. I think this should work fine.

13

I tried your suggestion and got this:

is there a specific directory or folder i should be in to do this?

Sorry, i am very new to this.

Brad

Okay, I suspected that this will be your next question :slight_smile: Do you have mysql (as in database) installed? Also, I believe you need to install devel packages for mysql. I don’t know how to install packages on a Mac, so please use Internet search.

Thanks, Abhinav

I cant seem to figure this out at the moment, but thank you very much for your help.

Brad

You can read this thread: http://www.ruby-forum.com/topic/125473 It discusses the same problem.

Do you have XCode (Mac OS X developer tools) installed? The installer is on your OS install disk, or can be downloaded free from www.apple.com/developer.

Also, try using SQLite, instead of jumping into MySQL. You will need to change your database.yml file to look something like:

development:   adapter: sqlite3   database: db/development.sqlite3

and I don't recall if OS X comes with the SQLite gem installed, so do:

sudo gem install sqlite3-ruby

I do not think I would advise using SQLite -- it's kind of underpowered for Rails, as I understand. I would, however, suggest using PostgreSQL instead of mySQL.

There are many websites with instructions on how to get all this running. If you find a tutorial for Tiger or earlier, just disregard the part about installing Ruby.

However, I'm not sure why you bothered with Rubystack. Mac OS's dev tools include Ruby and Rails already, and the other components are easy to install on their own. If you type 'which ruby', does that point to Apple's Ruby or Rubystack's Ruby? Some of this might be path issues.

Best,

hey john,

thanks. i will try that now. i have xcode installed. Before posting on here i posted on another forum. I was doing this tutorial: http://developer.apple.com/Tools/developonrailsleopard.html

i got to point 7 where is says to start the server after doing everything that is says above it.

I got this error from the debugger:

[Session started at 2009-09-10 09:20:44 +0100.] env: ruby: No such file or directory

The Debugger has exited with status 127.The Debugger has exited with status 127.

On the other forum, someone suggested that i use rubystack and thats where i started having the other problems listed above. if you could tell me what is up with the error above i will be more than happy :slight_smile:

Im off to try your first suggestion.

In response to marnen, it points to apples ( i think ): /usr/local/bin/ ruby
