NoMethodError: private method `open' called for Gem::Package:Class An error occurred while installing rake (10.0.3), and Bundler cannot continue

Question

I am trying to work on a ruby on rails project I synced from github. Even though rake-10.0.3 gets installed successfully, 'bundle install' fails. I am new to rails and not sure how to proceed on this.I googled the error, and tried the installing different versions of rake as suggested by the solutions, but it did not help.

Here's what I am trying to do... Please help.

Make sure that `gem install rake -v '10.0.3'` succeeds before bundling.

Thank you!

Solution

You should first update Rubygems:

gem update --system

And then update Bundler:

gem install bundler
