Problems with migration from older ruby/rbenv

Question

I faced with the following problem: I update my OS X to Yosemite, switched to ruby 2.2.2 and decided to come back to my Octopress-based blog. Below I try to describe all my actions one by one, will be glad if someone tell me where I did something wrong. So I cloned my page from github , checkout to source branch. But when I try to execute any rake command I get error:

rbenv: version `1.9.3-p194' is not installed
rbenv: version `1.9.3-p194' is not installed

I did:

> rbenv local --unset
> rake reharsh --trace
rake aborted!
LoadError: cannot load such file -- bundler/setup
MYPATH/Rakefile:2:in `<top (required)>'

Thus I install bundler:

> gem install bundler
> bundle install
Fetching gem metadata from http://rubygems.org/...........
Fetching version metadata from http://rubygems.org/...
Fetching dependency metadata from http://rubygems.org/..
Installing rake 0.9.2.2
etc

Finally:

> rake generate --trace
rake aborted!
Gem::LoadError: You have already activated rake 10.4.2, but your Gemfile requires rake 0.9.2.2. Prepending `bundle exec` to your command may solve this.

UPD: Following advices of K M Rakibul Islam, I changed in the gemfile rake version from 0.9.2 to 10.4 and added line gem 'iconv' to the gem file. After that rake generate start working.

As the error message suggests, you should run the rake command using bundle exec in order to run it in the context of your Gemfile:

bundle exec rake generate --trace

This should fix your issue.

Update

change this: gem 'rake', '~> 0.9.2' to gem 'rake', '~> 10.4.2' in your Gemfile and run: bundle install.

Am I right that in this case I will use older version of rake? – Kirill Lykov Nov 19 '15 at 03:36
whatever version you have in your `Gemfile`, using bundle exec, you will be using that version. But, I think you should just update your rake gem: `bundle update rake`, because you have a really old version of the rake gem in your `Gemfile` – K M Rakibul Islam Nov 19 '15 at 03:38
I tried to do that but it only updates a little - saying `Installing rake 0.9.6 (was 0.9.2.2)` instead of 10.x – Kirill Lykov Nov 19 '15 at 03:44
change this: `gem 'rake', '~> 0.9.2'` to `gem 'rake', '~> 10.4.2'` and then try again. – K M Rakibul Islam Nov 19 '15 at 03:51
