Hi list.
I''ve added the following line to my `config/environment.rb` file,
within
the `Initializer`:
config.gem ''mislav-will_paginate'', :version =>
''2.3.11'', :lib =>
''will_paginate'', :source =>
''http://gems.github.com''
When I then run the command `sudo rake gems:install`, I get the
following output:
tkn@tkn-desktop-ubuntu ~/work/trunk $ sudo rake gems:install
(in /home/tkn/work/trunk)
Missing these required gems:
mislav-will_paginate = 2.3.11
You''re running:
ruby 1.8.6.287 at /usr/local/bin/ruby
rubygems 1.3.1 at /home/tkn/.gem/ruby/1.8,
/usr/local/lib/ruby/gems/1.8
Run `rake gems:install` to install the missing gems.
What is going on here?

What version of rails are you running? --Matt Jones On Jun 26, 6:09 am, Troels Knak-nielsen <rails-mailing-l...@andreas- s.net> wrote:> Hi list. > > I''ve added the following line to my `config/environment.rb` file, within > the `Initializer`: > > config.gem ''mislav-will_paginate'', :version => ''2.3.11'', :lib => > ''will_paginate'', :source => ''http://gems.github.com'' > > When I then run the command `sudo rake gems:install`, I get the > following output: > > tkn@tkn-desktop-ubuntu ~/work/trunk $ sudo rake gems:install > (in /home/tkn/work/trunk) > Missing these required gems: > mislav-will_paginate = 2.3.11 > > You''re running: > ruby 1.8.6.287 at /usr/local/bin/ruby > rubygems 1.3.1 at /home/tkn/.gem/ruby/1.8, > /usr/local/lib/ruby/gems/1.8 > > Run `rake gems:install` to install the missing gems. > > What is going on here? > -- > Posted viahttp://www.ruby-forum.com/.

Some gems are loaded by the Rails initializer, so if they are missing, the rake tasks can''t be loaded. It''s a catch-22 really. I wrote a wrapper script to fix it. If any body else needs it, you can get it from here: http://gist.github.com/136461 Just put in `script/install_gems` and remember to `chmod +x`. -- troels -- Posted via http://www.ruby-forum.com/.

I use mislav-will_paginate. I place the following at the bottom of my environment.rb file: require "will_paginate" Make sure you place it after the end in configs... I''m using 2.3.2 -- Posted via http://www.ruby-forum.com/.
You shouldn''t be seeing this problem with 2.3.2 - I just tried it in a fresh Rails app using the 2.3.2 gem. Something weird''s going on in your version, as the install task sets $gems_rake_task which *should* prevent the display of the error message you''re seeing. Do you happen to have an RC version frozen in vendor/rails? That''s my next guess... --Matt Jones On Jun 27, 2:51 pm, Troels Knak-nielsen <rails-mailing-l...@andreas- s.net> wrote:> Matt Jones wrote: > > What version of rails are you running? > > 2.3.2 > > I found out what the problem is though.

Since it is an open source project, you can easily grab it from here and verify for yourself the problem: http://github.com/ari/clockingit/tree/master Ari Maniatis
Matt Jones wrote:> Do you happen to have an RC version frozen in vendor/rails? That''s my > next guess...Nope, but it''s an application that has been upgraded from an older version, so there might be some leftover somewhere, that is causing this. I''ll try to see if I can replicate the issue in a fresh project. -- troels -- Posted via http://www.ruby-forum.com/.
Ari: your problem is in lib/tasks/localization.rake. You require config/environment, which loads the initializer and causes the error. The gems tasks never even get a chance to run. Troels - I''d recommend that you look for the same kind of thing in your Rakefiles. --Matt Jones On Jun 28, 6:37 pm, Ari Maniatis <a...-WeiC9bTY98EQrrorzV6ljw@public.gmane.org> wrote:> On Jun 29, 4:03 am, Matt Jones <al2o...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote: > > > You shouldn''t be seeing this problem with 2.3.2 - I just tried it in a > > fresh Rails app using the 2.3.2 gem.

Matt: thank you so much for finding that. I have removed it and the problem goes away as you say. Can I recommend some improvements to Rails to help others in this predicament: * rake gems:install should not try to load all the rake tasks since it has a very specific job to do and should not be sidetracked by loading everything it comes across on the class path * better error reporting which detects this condition and reports where the problem might lie Thank you again for your help.

Matt Jones wrote:> Troels - I''d recommend that you look for the same kind of thing in > your Rakefiles.Indeed - I had a rake task in `lib/tasks/` that included `config/environment.rb`. Thanks for your help. Ari Maniatis wrote:> * rake gems:install should not try to load all the rake tasks since it > has a very specific job to do and should not be sidetracked by loading > everything it comes across on the class pathThat''s not possible. Rake works by finding files with the name *.task and then loading them. If these files try to invoke gems at load-time, there is nothing rake can do. It''s a fundamentally design flaw/limitation of rake.> * better error reporting which detects this condition and reports > where the problem might lieWould definitely be nice with a trace that points to the error. An solution could also be to move the `config.gem` lines from `config/environment.rb` into a separate file (Say - `config/gemconf.rb`), and then include it in the config file. This would make it possible to write a script in `script/`, that loads this config file and invokes gem for each dependency. Since it doesn''t depend on rake, it wouldn''t have the load-time-dependencies problem. The reason I''m suggesting this is that some times you really need load-time dependencies in your rake tasks; Namely if your task extends some generic task, present in a gem. For example, installing the `rails_rcov` plugin [1] will cause an error if you don''t have the `rcov` gem installed, since the task depends on the file `rcov/rcovtask`. Having a script that didn''t use rake, would solve this problem entirely. Might the rails developers be interested in a patch for this?

FYI, I have created a plugin, that moves gem-dependencies into a
separate file (`config/gemconf.rb`) and then makes `script/install_gems`
use this file for finding dependencies. This makes the install script
completely independent of rake and any rake tasks.

You can install it to you existing Rails projects, using:
./script/plugin install

Hope this helps someone.

I am using your plugin now. It is working well. Although I had to comment out ''unless local_install'' line 55 as I''m not running as root but do have superuser access(cygwin). Thanks for developing this plugin! -- Posted via http://www.ruby-forum.com/.
