rvm conflit with sqlite3

Question

$: /Users/dev/.rvm/gems/ruby-1.9.2-head@rails3/gems/sqlite3-ruby-1.3.1/lib/sqlite3/sqlite3_native.bundle: [BUG] Segmentation fault ruby 1.8.7 (2009-06-12 patchlevel 174) [universal-darwin10.0]

Abort trap

It's seem that ruby is not the correct version (1.8.7) but :

$: ruby - v
$: ruby 1.9.2dev (2010-07-15 revision 28653) [x86_64-darwin10.4.0]



$: gem list

Any ideas ?

Thanks very much :)

Answer 1

Had the same issue after moving to 1.9.2p0, but restarting the console on Snow Leopard did the trick. Seems rvm might have gotten confused.

Answer 2

Same problem for me on Snow Leopard; even though under rvm 1.9.2@rails3, I can see correct rails version number.

I have to use following command to use rails command:

ruby which rails g scaffold User name:string bio:text

Any solution?

I've finally found the reason. Looks like gem install rails is not managed to install the proper binary for rails in rvm. And rails is still references /usr/bin/rails, which have a #! line point to System ruby.

You can see it with:

head -1 `which rails`

which returns:

#!/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/bin/ruby

Change that to:

#!/usr/bin/env ruby

will fix the problem. I don't know if this problem affect other executable scripts gem installs, but why gem not install rails to rvm's own bin path is a mystery to me. Anyway, this workaround do the dirty for me.
