Bundle Conflicts

[nspeaks]

I am trying to follow your installation guide and upon executing the following command

gem install bundler --no-document

I am getting the following error

Fetching bundler-2.0.2.gem
bundler's executable "bundle" conflicts with /home/mastodon/.rbenv/versions/2.6.1/bin/bundle
Overwrite the executable? [yN]

What am I supposed to do here?

I am trying to install it on Ubuntu 18.04 in an EC2 instance.

Can you check which version of bundler you have in .rbenv? If it’s not too old I’d skip this step altogether.

Am still new to all this. So pardon me for asking, but how to check?
