Upgrading to rails 3

Rails
1

I’ve installed rails_upgrade plugin with ruby script/plugin install
GitHub - rails/rails_upgrade: Plugin to run checks on your Rails 2.x/3.x to check for obvious upgrade points on the path to 3.0.
Then if I run rake rails:upgrade:check it says
rake aborted!
no such file to load – initializer

What I’ve missed?

try adding trace to your rake command to get more information

rake rails:upgrade:check --trace

I just went through running rails_upgrade last night. I don’t remember
running into this problem. But, I wanted to ask if you were following
along with Ryan B.’ Railscast on using the gem.

I just followed along and my upgrade went pretty well actually. The only
major difference from what he shows and what I did was that now there is
a pre-release of will_paginate that works with Rails 3.0. I simply
specified the newer gem version in my gemfile instead of using the hack
Ryan shows to get around the problem.

Now I still have a lot of work to do to get my application fully up on
Rails 3.0. Unfortunately, I was still using a lot of old plugins that
I’ll finally be replacing with newer, better, solutions. But, as for the
assistance rails_upgrade provides things went pretty smoothly.

I’m having the exact same problem. I would have loved to see the answer
here.

Here is with --trace option:

I don’t know what is the problem.

Try re-installing rails version that you are using, if you have frozen
rails
in your vendor directory, then remove it and use rails from gem or
remove it
and re-freeze

Most probably this issue is because rails is not installed properly or
is
not in the right path or has gotten corrupted somehow.
