When I try to do a rails s on my Rails 3.1 App I am getting:

回答1:
Looks like you are using the thin web server which relies on EventMachine for its network IO.
EventMachine contains native code which is compiled for your machine's architecture when the gem is installed. If the gems are moved between machines or the OS is updated or restored then you may need to recompile the native bits.
Since you are using an rvm gemset there is a simple command to recompile all gems in the current gemset:
rvm gemset pristine
Or across all gemsets:
rvm all-gemsets do rvm gemset pristine
回答2:
rvm use ruby-1.9.3-p448
fixed it for me. Maybe specify what you're using even if there's a default selected.
回答3:
Try to minimize the problem. Comment out some code. Remove some gems. Eventually you'll pinpoint exactly which piece is failing.
If all else fails, report it as a ruby bug at http://www.ruby-lang.org/bugreport.html
回答4:
brew install -f imagemagick --disable-openmp
回答5:
I have seen this problem when updating my OS. Did you recently upgrade to Mountain Lion or the like? If you are on a mac, make sure you have the xCode command line tools installed.
