Error creating Rails 3.0.pre Application

Prem, everything that I have tried seems to be working using Rails 3.0 beta and Ruby 1.9.1. Also, I guess the debugging code will be removed when Rails 3.0 beta goes to the Release Candidate (RC). Here's what I have tried so far:

$ ruby -v ruby 1.9.1p376 (2009-12-07 revision 26041) [powerpc-darwin9]
$ rails blog $ cd blog $ rails g scaffold post title:string body:text $ rake db:migrate $ rails server

However, when using Rails 3.0 beta and Ruby 1.9.2, I'm seeing the following issue when I attempt to perform the migration:

$ ruby -v
ruby 1.9.2dev (2010-01-18 trunk 26340) [powerpc-darwin9.8.0]
$ rake db:migrate

Lastly, I'll upgrade Ruby 1.9.2 from the sources and report back with my results.

I get the same using Ruby 1.9.2 revision 27203.

Please try installing the latest version of bundler, then gem cleanup bundler and then bundle install

Any new information regarding this ticket?

On windows, bundle_if_dev_or_edge fails because it is setting bundle_command to bundle.exe which should be bundle.bat. Not sure if I should write another ticket for this or not. Here is a possible fix but this pulls in rake. Might want to pull this rake functionality into thor

dominic, can you share pastie of above code snippet? It's not readable.

Did you see the included windows.patch file in my above message?

I had this same problem which I could solve by running 'bundle exec bash' and then running rake through that new shell. I was able to make a regular shell work correctly by making sure the environment variables in the bundled bash be the same as a regular shell. You can see your environment variables by running 'env'. I went into my ~/.bash_profile (I think ~/.profile also works if you have that, or maybe ~/.bashrc) and added a couple of export lines and modified my PATH to point to my bundle bin directory.

The exact changes for me were to add the following (this is on a snow leopard box):

export BUNDLE_GEMFILE=/Users//Work/liveops/trunk/Gemfile
export RUBYOPT="-I/usr/local/lib/ruby/gems/1.9.1/gems/bundler-0.9.25/lib -rbundler/setup"
(and then I added this at the very bottom of the file) export PATH="/Users//.bundle/ruby/1.9.1/bin:PATH"

Hope that helps somebody.

I was going to ask about this ticket earlier too, and so tempted to mark as stale.

If anybody still having this problem on RC and the latest bundler, please let me know. Or else I'd have to mark it as invalid.

Please forget my previous comment.
I have resolved my error and has nothing to do with rails, rake, bundle nor ruby-1.9.2.
There was an old rspec.rake file in my lib/tasks folder generating all the troubles.

Thanks.

This ticket can be officially closed because I'm no longer experiencing this issue in the current Rails 3.0 RC.
