I've tried to look up other occurrences of this issue and have found similar things (eg Spring and middleware conflict? ) but none of them solve my problem. I'm pretty sure it's an environment thing, but can't figure it out. I would have thought that fresh installs of ruby, rails and a newly created rails app would just work, but it seems not. Any suggestions much appreciated. I should add that if I do the same on ruby v 2.6.6 it works fine.

Thanks

I have a very similar set up as you (ruby 2.7.1, MacOS 10.15.5, bundler 2.1.4, etc.) and I ran into a similar issue. Saw this statement in a popular rails tutorial (see image). Lots of people have issues with spring so try creating a new rails app without the spring and listen gems (in terminal write: $ rails new blog --skip-spring --skip-listen). Hope this helps!
