Is anyone else getting annoying warning messages?

/usr/local/bin/rails:17:Warning: require\_gem is obsolete. Use gem  
instead.

I get these messages when using the rails command, rake, script/generate  
etc etc.

I’m using Rails 1.2.1

You can fix it in environment.rb. Find the ‘require\_gem’ lines and  
replace them with ‘gem’

This has more to do with the new rubygems than rails - new versions of  
everything seem to be coming out at once!

I don’t think that’ll work. I did it on my machine immediatly I upgraded  
gems, and _still_ had to fix my rails app.

I got the impression it only fixed the binstubs - ‘rails’, ‘rake’, ‘cap’  
etc I dont think it’ll search out uses of require\_gem in rb files on  
your machine ?

Actually, do:

```
gem pristine --all

```

You’re right. The moment I saw it, I thought it was the ‘official’ fix.  
I was wrong. Doing a `rake db:migrate` produces the warning. Very  
irritating.

You can fix it by editing your environment.rb as described earlier in  
the thread.

boot.rb contains the `require_gem` piece of code.

Here’s the ticket for it:

I hope it’ll get fixed soon. It’s very off-putting seeing that warning  
each time doing something.

I’m pretty sure you want to do

```
sudo gem update
```

I’m pretty sure that I am not alone with this problem since upgrading to  
gem 0.9.1

Removing

/usr/local/lib/ruby/gems/1.8/source\_cache

solved the problem for me.
