无法构建gem原生扩展ruby 2.0升级fastthread

Question

I am upgrading my system to ruby 2.0 and I have done everything short of throw my computer on the wall. I find it hard to believe that fastthread is the problem. Has anyone else seen this error when running 'bundle install'. Here is my ruby version

ruby -v ruby 2.0.0p0 (2013-02-24 revision 39474) [x86_64-darwin12.2.0]

when I try to run rails -v I get this

rails -v Could not find fastthread-1.0.7 in any of the sources Run bundle install to install missing gems.

Answer 1

Phusion Passenger 4 has already solved this by removing the fastthread dependency. The 4.0 betas and RCs install just fine on Ruby 2.0.

Answer 2

If you use Passenger as your webserver you have to have this dependency. See this pull request for the fix: https://github.com/zoltankiss/fastthread/commit/a47a121990cf7d4f31147406c2d379dabc048479

The author of the gem has not yet included this fix. You can require fastthread from https://github.com/zoltankiss/fastthread if you need it. That is who submitted the pull request.
