From Instant Rails 2.0 to Rails 2.1.0

Rails

hi,

I have installed Instant Rails 2.0 on my machine which comes with
Rails 2.0.2. Now I want to update my Rails to version 2.1.0. So I do
gem update rails and It seems to be fine. But when I check the version
of my Rails I get the following message:

rails -v
C:/RoR/ruby/lib/ruby/site_ruby/1.8/rubygems.rb:578:in
report_activate_error': RubyGem version error: activesupport(2.0.2 not = 2.1.0) (Gem::LoadError) from C:/RoR/ruby/lib/ruby/site_ruby/1.8/rubygems.rb:134:inactivate’
from C:/RoR/ruby/lib/ruby/site_ruby/1.8/rubygems.rb:158:in activate' from C:/RoR/ruby/lib/ruby/site_ruby/1.8/rubygems.rb:157:ineach’
from C:/RoR/ruby/lib/ruby/site_ruby/1.8/rubygems.rb:157:in activate' from C:/RoR/ruby/lib/ruby/site_ruby/1.8/rubygems.rb:49:ingem’
from C:/RoR/ruby/bin/rails:18

Please help! Thanks…

Looks like it didn’t get it all done. I successfully updated my copy of
IR2.0 but did a gem update --system first. Also, I did gem update rails
-y
to include the dependencies. Also, I went back and uninstalled the down
versions (e.g., rails2.0.2). It’s not supposed to be necessary but I
prefer
a ‘clean’ copy.

HTH,
Bill

(sorry if it is a double post, having some google-groups issues…)

i’m trying to update too, so i can use the new cache features, but
when i try to use the method “Rails.cache.write” in my controller
i get the message

“undefined method `cache’ for Rails:Module (NoMethodError)”

and if i try to set the cache store
(“ActionController::Base.cache_store = :memory_store”)
i get: “undefined method `cache_store=’ for
ActionController::Base:Class (NoMethodError)”

the version message is “Rails 2.1.0”, so i assume that the version is
ok.
does anyone know what could be the problem? thanks.

i just updated my instant rails today. i did:

1 - gem update --system
2 - gem update rails -y
3 - gem uninstall rails (not really necessary)

and i had to do it twice, as the first time the
update was not properly done. it could be nice
to delete everything and start from scratch, i
did that.

But I got the same error message. (I also tried without this first
step…)

What did I miss there? Thanks…

Did you do anything between downloading/unzipping InstantRails-2.0-
win.zip and your 3 steps?

Here is my problem: after the 1st step, I did the following and got an
ERROR message.

C:\RoR2\rails_apps>gem update rails -y
Updating installed gems
Updating rails
ERROR: While executing gem … (Gem::InstallError)
invalid gem format for C:/RoR2/ruby/lib/ruby/gems/1.8/cache/
activesupport-2.
1.0.gem

Hints? Thanks…

try gem cleanup -v, this should get rid of the old gem versions

I had the exact same problem as you today. I ran this command and it
fixed the problem:

“gem uninstall rails”
“gem install rails”

Hope this helps.

See screenshot:

Any ideas?
Thanks,

Need to MANUALLY dowload the Activesupport 2.1 gem, install using the
–local option, THEN
do “gem install rails”

I was told there is a repository problem…

I tried all the suggestions above but none of them worked.

I just wonder isn’t updating Instant Rails (which contains Rails 2.0.2
now) to Rails 2.1.0 something simply and very desired? Shouldn’t there
be some standard procedure for that?

It is just so frustrated…

Try:

Start InstantRails
Menu -> Rails Applications -> Open Ruby Console Window
at prompt: gem install rails
