I tried to freeze Rails version 1.2.3, but after doing so I get this  
error when starting my development server:

./script/…/config/…/vendor/rails/railties/lib/initializer.rb:43:in  
`send': undefined method`install\_gem\_spec\_stubs’ for  
#Rails::Initializer:0x2b70410 (NoMethodError)  
from ./script/…/config/…/vendor/rails/railties/lib/initializer.rb:  
43:in `run' from ./script/../config/boot.rb:46:in`load\_initializer’  
from ./script/…/config/boot.rb:38:in `run' from ./script/../config/boot.rb:11:in`boot!’  
from ./script/…/config/boot.rb:109

from ./script/server:2  
from -e:4:in `load’  
from -e:4

Anyone have any ideas as to why this is happening? Thanks.

Hi, if you used the following command to freeze Rails:  
rake rails:freeze:edge

a) update your environment.rb by making sure that it contains

```
 RAILS_GEM_VERSION = '2.1.1'

```

b) run the following command in the root of your rails application:

```
  rake rails:update

```

rake rails:freeze:gems

a) run the following command in the root of your rails application:

```
  rake rails:update

```

Good luck,

-Conrad

Sounds like you’ve got a mismatch between the version of rails frozen  
and the boot.rb in your app.  
rake rails:update should update boot.rb to the correct version.
