The command "gem install rails" will overwrite some commands, in particular the rails command in you path, but the rails command is also part of the gem. Your current rails command will be 1) in your path and 2) in some location like /usr/local/lib/ruby/gems/1.8/gems/ rails-*/bin where the * stands for the version of rails.

Just move rails into the "/vendor" directory of each project using subversion (old versions) or git (newer versions). For example, I use rails 1.2.3 for zena cms so I use (in the vendor directory): # svn export -r 6633 http://svn.rubyonrails.org/rails/trunk/ rails Gaspard> > hi all, > can i install different rails versions on single machine like rails > 1.2.2, 1.2.6, 2.0,2.1 etc to workout different applications in > different > rails versions. if yes, how? currently i''ve rails 1.2.6 and if i run > command as "gem install rails", will it overwrite my current rails > version? what should i do to keep older and new both versions at the > same time? > > -DP > -- > Posted via http://www.ruby-forum.com/. > > >--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

And if you need to run the actuals rails executable you can specify the version you want eg rails _1.2.6_ to run version 1.2.6 (assuming you have the corresponding gem) --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

hi, thanks for reply. wt i was thinking that i could install all those versions on single machine and just change RAILS_GEM_VERSION in config/environment.rb file. can this be done? @yesterday couldn''t get wt exactly u want to say. can u explain it a bit more on that pls? if i do "gem install rails", will rails-1.2.6 folder be thr only in "C:\ruby\lib\ruby\gems\1.8\gems"? and can i use it RAILS_GEM_VERSION in config/environment.rb file? @gaspard "Just move rails into the "/vendor" directory of each project using subversion (old versions) or git (newer versions)." sorry, i''m not much aware of git or subversion. but wt exactly u mean by rails here? "C:\ruby\lib\ruby\gems\1.8\gems\rails-1.2.5" is it? don''t i have to install all rails versions on the machine before that? what if i want to have rails 2.0? can "gem update rails" fix this? i hope i''m not creating any confusion :D. if so, pls let me know. thanks. P.S.:i''m using windows,rails 1.2.6 -DP -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

When you install a gem, you can pass it -v to tell it what version you want. Without -v, the latest version is installed. So install rails 2.1 _right now_, you could do gem install rails But if you want to install 1.2.6, you would do gem install rails -v 1.2.6 gem actually has pretty good help. gem help commands is a good place to start. Then you can get specific with gem help install Peace, Phillip -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

You can can get all parts of rails (activerecord, actionpack, etc)
using subversion (http://subversion.tigris.org) or git (forgot website
name). The command using subversion would be:
# cd vendor
# svn export -r 6633 http://svn.rubyonrails.org/rails/trunk/ rails
Replace "6633" by the revision number containing the versions that you
want. Doing this, you get to use specific copies for your app, without
using the gems for rails stuff. You can use the "previous change",
"next change" on the old trac browser to find the revision you need
(if you know rails version):
http://dev.rubyonrails.org/changeset/7843/trunk/railties/lib/rails/version.rb
You end up with a folder containing:
your app
+- app
+- ...
+- vendor
+- rails
+- actionmailer
+- actionpack
+- actionwebservice
+- activerecord
+- ...

gem install rails -v=<%=version you want to install%> eg: gem install rails -v=1.2.5 will install the rails version 1.2.5 for you. Infact this option is available while installing any gems. With the option "-v=" will always install the latest version of and gem. You can freeze a different version of rails for an different project. In config/environment.rb specify which rails version you wan to use for that particular project.
