Rails segmentation fault when starting server?

Question

Trying to get my rails 3 environment up and running and I keep encountering an error I can't get around. Any help would be great appreciated!

Here is the problem:

Patrick-Scotts-MacBook-Pro:~ PJS$ cd hope_app
Patrick-Scotts-MacBook-Pro:hope_app PJS$ rails server

Answer 1

I have exactly the same versions you have and I don't see this. But I'm not on Macbook Pro.

It's hard to say whether this is a Ruby 1.9.2 problem (as it's still not considered stable enough to be officially released) or whether this is actually a bug in the Sqlite 3 gem. Exactly the same bug was reported against the gem for a slightly earlier version of Ruby 1.9.2.

You might try dropping back to Sqlite version 1.3.0 or back to Ruby 1.9.1 temporarily until the issue resolves itself. Hardly a satisfactory answer but at least you could be productive again.
