First time rails install, help with gems/rake

Question

Hello all, I just did a first time ruby enterprise edition, installed some gems, and now I'm trying to do a
' sudo ./rake gems:install' and getting a:

rake aborted!
No Rakefile found

error. Firstly, what directory should I be doing this from?

Here are the steps I've followed:
download ruby enterprise from http://www.rubyenterpriseedition.com/download.html wget http://rubyforge.org/frs/download.php/68719/ruby-enterprise-1.8.7-2010.01.tar.gz

./ruby-enterprise-X.X.X/installer

/opt/ruby-enterprise-1.8.7-2010.01/bin/gem install mysql

ln -s /opt/ruby-enterprise-1.8.7-2010.01/bin/gem /usr/bin/gem
ln -s /opt/ruby-enterprise-1.8.7-2010.01/bin/rake /usr/bin/rake

and I've installed several gems

I have found the appropriate directory (I think), and am still getting errors. Here's a copy of rake with --trace:

dan@dev:~/myApp.com-ror$ rake --trace gems:install

/usr/bin/rake:19

And what should database.yml look like?

Answer 1

If you have not set your path up correctly then you will need to run this from the rails directory.

Answer 2

rake gems:install is to install gems for your app. You have to run this inside your app root directory. To install gems on your machine use gem install.

Answer 3

Ok I've looked in the docs

$ /opt/ruby-enterprise-X.X.X/bin/gem install rails

in your case means just:

gem install rails

When you mentioned ' sudo ./rake gems:install' what were you trying to achieve?

Once installed rails do:

rails myproject

And there you go.
