About bundler compatible versions

#1

Can anyone help me out to solve this error

It’s telling you that you don’t have the correct version of bundler installed.

Are you using rvm or rbenv?

You can install 1.6.9 of bundler by running:

gem install bundler --version="1.6.9"

I tried it but didn’t work for me…I am using rvm.
