Installing Rails Help!

Hi,

I followed a Tutorial on Nettuts to install Ruby with RVM and this went
well. I then tried to install Rails to follow the 'How to build a dropbox
live service' from Netttus but appear to get errors can anybody help?.

Once I installed rails I created a new rails project using the command

(Rails new sharebox -d mysql)

This worked and created the folder structure.

I then went and added the following to the gem folder for the project as
suggested by the netuts tutorial

source 'http://rubygems.org'

gem 'rails', '3.0.3'
gem 'ruby-mysql'

I then did the bundle install but this kept causing errors, eventually
somehow I got this to work and it said bundle installed correctly.

However when I try the command rails server i get the following error:

/Users/bengibson/.rvm/rubies/ruby-1.9.2-p290/lib/ruby/site_ruby/1.9.1/rubygems/dependency.rb:247:in

Could anybody help me out (i'm new to terminal so need simple explanations),
or help me completely uninstall rails and rubygems and start from scratch.

Try "bundle exec rake db:migrate"

TRY rake fuck

Use gem ‘mysql’

Do not Use gem ‘ruby-mysql’

Please use

gem ‘mysql’

for rails 3

gem ‘mysql’, ‘2.8.1’

Hi, thanks for the help

Didn't work unfortunately, it gives the error

Bens-MacBook-Pro:sharebox bengibson$ bundle exec rake db:migrate
rake aborted!
undefined method `groups' for Rails:Module

why bundle exec rake db:migrate?

first u have to intialize all gem so use

bundle install
or bundle update

then make sure you have install mysql-server and mysql-client

before doing all stuff other wise

install mysql client

Please refer this

http://forums.mysql.com/read.php?116,178217,178217

That might be because of the mysql2 adapter is missing
let me know your environment details including os..

I'm working on a late 2009 Macbook pro with the latest version of OSX lion.
Not sure what other information you need. let me know

Thanks

why mysql2

just install mysql-server
mysql clint
and libmysqldev

other libraries
then install mysql gem 2.8.1

it will run

no required mysql2

I am working on windows 7 32 bit. I came across the same problem. But
for me the below procedure worked great!

1. edit Gemfile => gem 'mysql2', '0.2.6'
     2. download mysql-noinstall-5.1.50-win32.zip at
http://downloads.mysql.com/archives/mysql-5.1/mysql-noinstall-5.1.50-
,unzip
     3. gem install mysql2 -v 0.2.6 – --with-mysql-lib=E:\ROR
\mysql-5.1.50-win32\lib --with-mysql-include=E:\ROR\mysql-5.1.50-
win32\include (replace the file "E:\ROR\mysql-5.1.50-win32" path
with
yours)
     4. this should work now,try bundle install,generate some
model ,and run rake db:migrate to see if it works,make sure your
database config is right,like this
development:
  adapter: mysql2
  encoding: utf8
  reconnect: false
  database: depot_development
  pool: 5
  username: root
  password: root
  host: localhost
   5.if it still not work ,try this => https://github.com/brianmario/mysql2/issues/8

Really dont know how to install this mysql library stuff.

Detailed instructions or links to downloads would be much apprenticed

thanks

Dear ben, trust google and do the related search like installing mysql
libraries to your environment.
Do it first. Thats the problem, your system is missing mysql libraries
for sure. If it is windows i could have definitely helped you!
