I suspect either you don’t have 1.1.6 installed, verify by running “gem query list” from cmd line. Or, you application is pegged to 1.2. Did you “rails my\_app” with 1.2 installed? You may want to delete and redo that command with 1.1.6. Also, you can check which rails version your app is pegged to by looking in environment.rb You will see something like… # Specifies gem version of Rails to use when vendor/rails is not present RAILS\_GEM\_VERSION = ‘1.1.6’ if it says 1.2.1, that’s at least part of your problem. /ak dan schrieb: ---

thanks for your input on this. just a quick run down of wher i am: 2 days ago i installed ruby/rail/mySQL. i went through a tutorial, created a skeleton site and all works as expected. my client then sent me their site that is already been done in ruby. for starters i couldnt find the script folder so i couldnt run the command: ruby script/server. i copied over a ‘script’ folder into the site to allow me to try and preview it. teh rails i installed has gems v1.2.1, but my clients site uses gems v1.1.6. ive downloaded gems 1.1.6 and did all it said to install them, but it doesnt seem to have installed them!? if i change the environment.rb file to use 1.2.1 then i get the error that youve seen, if i change it to 1.1.6 then it says it cant find ‘gem for rails 1.1.6’!? so it looks like a simple install of 1.1.6, but i cant get it working!? also, its probably best if it uses the latest version of rails (1.2.1) anyway. ive run the command gem query list and it says: [http://www.timbirkett.co.uk/er2.gif](http://www.timbirkett.co.uk/er2.gif) so it looks like 1.2.1 is installed even though ive done everything to properly install 1.1.6. you said: “Or, you application is pegged to 1.2. Did you “rails my\_app” with 1.2 installed? You may want to delete and redo that command with 1.1.6.”. i dont know what you mean “rails my\_app”. how do i delete and redo this? ive been in the environment.rb file and when i change it to 1.1.6 is says “cannot find gem for rails 1.1.6”. (ive mentioned this already above!). if i change it to 1.2.1 then i get the error:[http://www.timbirkett.co.uk/er.gif](http://www.timbirkett.co.uk/er.gif). im going in circles with this! thanks for your help. - D ---

thanks dan, ill try your suggestions. someone mentioned on another forum that it could be the file column plugin and to uninstall the plugin, but i wasnt sure what he meant by this (i havnt heard of file column plugins). anyway, cheers. - D ---

Well, that’s sounds frustrating. first, “rails my\_app” was a bit vague, properly stated I meant the standard “rails /path/to/my\_app” command which generates the skeleton Rails application. I would caution against jumping straight to 1.2.1, if there are plugin dependencies in the app you could be headed for more heavy weather. Have you tried a “gem install rails -v 1.1.6”. You’ll need to specify 1.1.6, otherwise you default to 1.2. Try “gem install --help” for more details. I would “rails /path/to/my\_app” in a new folder to create a clean skeleton app with all necessary components. Then I would copy in (copy over as necessary) the client provided application.

i dont get this. i generated the skelton site and pasted over teh relevant docs with the existing website, try and do a ‘ruby script/server’ and still teh same errors. i did the ‘gem install rails -v 1.1.6’ and installed all its dependancies. ive just done a ‘gem -v’ (to get the version number), and its saying 0.9.0!? thats not right is it? ive done a ‘gem list --local’ to see what that did and it does mention (along with a list of other stuff): rails(1.2.1, 1.1.6) AND actionwebservice(1.2.1, 1.1.6). so have i got both versions now on my machine? strangeness… ---

yes, you have both rails on your machine. gem -v is telling you the version of the RubyGems package manager. Thus 0.9.0 is correct. going back to the original error post, look at environment.rb line 59. My guess is that you’ll see some sort of Plugin include statement. If it’s not installed in the vendor/plugins folder, well that would be a problem. then you’ll need to do (from app root) “ruby script/plugin install required\_plugin\_name\_here” /ak dan schrieb: ---

hi, ok, i think ive got it sussed. i found the file column plugin which is used for file uploads. ive wrote the cmd line to download it and tat seems to have done it! i wander why it wasnt installed with all teh other plugins i dowloaded? (i still cant find any of those!) anyway, thanks for all your help. now ive got to figure out how to get their existing db (which looks like its mySQL) working (only ever used access before). anyway, many thanks - Dan ---

hi dan, on line 59 it does mention file column but no mention of plugins. this is what it says in my environment file from line 56 to line 62: FILE\_COLUMN\_PREFIX = ‘images’ module FileColumn module ClassMethods DEFAULT\_OPTIONS[:root\_path] = File.join(RAILS\_ROOT, “public”, FILE\_COLUMN\_PREFIX) DEFAULT\_OPTIONS[:web\_root] = “#{FILE\_COLUMN\_PREFIX}/” end end ive installed every plugin available (although nothing has appeared in my vendor/plugins folder?). and restarted the webrick server (it said somewhere to do this for the plugins to take effect.) still no joy, comes up with the same errors. any suggestions? thanks for your help on this. im learning a lot as i go along(!) - D
