Error: cross-thread violation on rb_gc()

Question

I\'m new to Ruby on Rails.

I ran the following in a terminal when I was going through creating a blog tutorial with Rails:

$ rails blog
[BUG] cross         


        

Answer 1

I had a similar problem installing buildr gem (using rvm). This solution helped:

I could nail this bug down to the native extensions of the ruby-java-bridge (rjb) on Mac OSX. What you want to do to fix this is the following:

gem uninstall rjb
gem uninstall buildr

When asked just uninstall all versions.

gem install rjb -v 1.3.3 --platform ruby
gem install buildr

This will install the ruby version of rjb and not the native darwin version. This should fix the issue.

Although, it's not related to the question, this may help those who will look for the same error message.
