Middleman-cli's executable "middleman" conflicts with middleman-core

I wanted to try a fresh install of current Middleman 4.3.6 on an empty folder. My environment: macOS Mojave 10.14.6, RBenv set to Ruby 2.6.5, created a fresh empty folder, typed gem install middleman and after a few Fetching … I have a surprise:

middleman-cli's executable "middleman" conflicts with middleman-core
Overwrite the executable? [yN]  

What did I do wrong?

The full log is:

I had the same prompt, on 4.3.6 as well…

I went with it, and opted [y] to overwrite… Haven’t had any issues… yet :slight_smile:
