rake stopped working

When I tried to use rake I got the following error message.

C:\projectsclone\treebook>rake routes rake aborted! Gem::LoadError: You have already activated rake 10.4.0, but your Gemfile require s rake 10.3.2. Prepending bundle exec to your command may solve this. C:/projectsclone/treebook/config/boot.rb:6:in <top (required)>' C:/projectsclone/treebook/config/application.rb:1:in<top (required)>' C:/projectsclone/treebook/Rakefile:5:in `<top (required)>' (See full trace by running task with --trace)

C:\projectsclone\treebook>

Was working fine until then.

Anyone got any suggestions?

I have no idea how rake updates got out of sync with the rest of my rails installation help.

Would a fresh installation help?

Steven,

I would follow the instructions in your error message and use bundle exec like so: 

bundle exec rake routes

This will sometimes happen when you have installed newer gem versions than those required or if your Ruby version has been updated and the gems you need to use haven't yet been updated to the spec of the new Ruby version.

The bundle exec will run the command in the context of the Gemfile used in the app and not the gem versions installed on your machine.

You could also edit the Gemfile itself to match the rake version that's called for in the error.

I did this the other day and it worked like a charm! :grinning:

I'll give it a try thanks.

Haven't been able to do much today because practically the whole of ruby / rails community was down due to DDOS attack on dnsimple name server. I was trying to do a fresh install with ruby > 2.0.0 and got caught in the middle. :(
