Solve uninitialized constant ActiveSupport::Dependencies::Mutex (NameError) in Rails 2.3.8
Hi all
If you get stuck with this strange error of uninitialized constant ActiveSupport::Dependencies::Mutex (NameError) don’t worry.
Just follow the steps below :-
gem update –system 1.5.3
once its installed successfully do gem list and see if you have any other versions of rubygems-update already installed. If so remove all the others apart from 1.5.3
Once you do that run the following command
update_rubygems
The above command will show that 1.5.3 is installed. Do confirm the same by checking the gem version gem -v
Hope this helps. In case you have any query related to this do post a comment and I will get back ASAP
