You have already activated rake 0.9.6, but your Gemfile requires rake 10.1.0. Using bundle exec may solve this

Question

Before continue reading, I must says that I already read and tried similar questions and answers on google & stackoverflow.

My problem is that:

• bundle install or update does nothing
• gem uninstall rake refuses because rake is a default gem
• I cannot use bundle exec for all my commands

Any other idea ?!

Answer 1

At the root of project, do:

gem list rake  

You will see probably more than one version. If so, then remove the version you don't need (i.e. 0.9.6) by command:

gem uninstall rake 

it will ask which version to remove. Or try doing

bundle update rake 

Answer 2

I solved this by just doing

gem install rake

Answer 3

This solved my issue

bundle update rake

Answer 4

You might have old version of rake installed. In that case, use:

gem list rake

If the output shows only one version as:

*** LOCAL GEMS ***

rake (0.9.6)

Then simply installed the newer version

gem install rake
