Your Ruby version is 2.7.0, but your Gemfile specified 2.6.6.

In my Ruby project, when I try bundle install, I got:

Your Ruby version is 2.7.0, but your Gemfile specified 2.6.6

I don't know how to solve it. I am using Windows Subsystem for Linux (WSL) Ubuntu 20.04 and Ruby 2.7.0.

I think you are working on qpixel. While, working on a big project don't change their version. Just change your ruby version. To change ruby version you have to use rvm

rvm install 2.6.6
rvm use 2.6.6

I think another type of login required in terminal (i forgot). If you can't execute above command normally than, try with sudo. I am sure that sudo can't execute them also. So, at first login using

/bin/bash --login

Then, execute those commands. I hope it will work now.
